100 Incredibly Interesting Facts About Japan

Updated September 2026. Originally published August 17, 2019. I went back through the list to update time-sensitive statistics, correct a few oversimplified claims, and keep the original photos and firsthand stories from our trips.

When I first published this article in 2019, I had already been to Japan three times, and I was completely hooked. The food, landscapes, neighborhoods, trains, traditions, and tiny details of everyday life kept giving me reasons to come back.

This list started as a month-long research project after those trips. A lot has changed since then, so I’ve gone back through all 100 facts and updated the time-sensitive numbers, corrected a few things that were oversimplified, and kept the original photos and firsthand stories from our trips.

Some facts are historical, some are weird, and some are just things I wish I had known before visiting. Here are 100 things about Japan I still find fascinating.

1.) Japan is Largely Made Up of 4 Main Islands

While Japan is an archipelago with 14,125 islands according to Japan’s 2023 Geospatial Information Authority recount, only four islands make up the majority of Japan’s land area. Honshu, Kyushu, Shikoku, and Hokkaido account for about 97% of the total area of Japan. The main cities like Tokyo, Osaka, and Kyoto are located on Honshu.

2.) Greater Tokyo Is One of the World’s Largest Metropolitan Areas

The greater Tokyo metropolitan area is one of the world’s largest metropolitan areas. Japan’s 2025 census preliminary results put Tokyo + Kanagawa + Saitama + Chiba at about 36.99 million people.

3.) Japan Remains Among the World’s Highest Life-Expectancy Countries

Japan remains among the world’s highest-life-expectancy countries. According to Japan’s Ministry of Health, Labour and Welfare figures for 2024, life expectancy was about 81.09 years for men and 87.13 years for women. Longevity in Japan is multifactorial – diet, daily walking, healthcare access, and social factors all play a role rather than any single cause.

4.) About 67% of Japan Is Covered in Forest

When you think of Japan, you probably think of the big cities first. Surprisingly, about 67% of Japan’s land area is covered in forest. I still remember exploring my first forest in Japan in the Mount Fuji area. There was a sign that warned visitors to watch out for black bears, and I honestly never thought black bears were roaming the forests in Japan until that moment.

5.) There are a Crazy Amount of Active Volcanoes in Japan

In total, Japan has 111 active volcanoes. The Japan Meteorological Agency continuously monitors dozens of them; current JMA material lists 51 continuously monitored volcanoes because they have erupted recently or because there is a meaningful chance of eruption.

6.) Japan Experiences Frequent Earthquakes

Yes – Japan is one of the most seismically active places in the world. Because the country sits near the boundaries of several tectonic plates (including the Pacific, North American, Eurasian, and Philippine Sea plates), it experiences frequent seismic activity. Most quakes are small ones you would never feel, but large and devastating earthquakes do happen from time to time.

7.) The 1923 Kanto Earthquake was the Country’s Deadliest Earthquake

Going off of #6, big earthquakes do unfortunately happen in Japan. The deadliest earthquake in the country’s history happened on September 1, 1923, and hit at a magnitude of 7.9. The earthquake is estimated to have lasted between 4 and 10 minutes, and in total about 140,000 people lost their lives. Since many of the houses in 1923 were made of wood, many people lost their lives in the fires that followed.

The 2011 Tohoku earthquake was Japan’s strongest recorded earthquake by magnitude (9.0) and generated a devastating tsunami. It is a separate story from the 1923 Kanto disaster – strongest by magnitude, not Japan’s deadliest by fatalities.

8.) Japan has the World’s Deepest Underwater Postbox

The deepest underwater postbox is located in Susami, a fishing town in Wakayama Prefecture, and was recorded by Guinness World Records in 2002. The postbox sits about 30 feet underwater and has become a quirky dive attraction for visitors who want to mail a waterproof postcard from below the surface.

9.) Mount Fuji is a Sacred Place

Mount Fuji isn’t just the tallest mountain in Japan – it has also been a sacred place in Shinto tradition since at least the 7th century. In Sengen worship associated with Mount Fuji, the kami Konohanasakuya-hime is closely linked with the mountain. Her symbol is the cherry blossom.

I was lucky enough to visit the Mount Fuji area. Although I am not a practitioner of Shinto, I definitely felt an otherworldly atmosphere and peacefulness as I walked around Lake Kawaguchiko in the shadow of Mount Fuji in the early morning sun.

10.) Japanese Culture Has a Deep Affection for Nature

Similar to #9, Shinto traditions often emphasize kami associated with natural features – rocks, mountains, rivers, and other parts of the landscape. That long-running spiritual relationship with nature shows up in festivals, shrine locations, and everyday seasonal customs across Japan.

11.) The Sea of Japan Holds an Abundance of Fish

The Sea of Japan has conditions that support rich biodiversity, including a higher-than-normal concentration of dissolved oxygen in places that helps many species flourish. Exact species counts vary by source and survey method, but the takeaway is simple: these waters are biologically rich.

12.) Its History Dates Back to About 30,000 BCE – 35,000 BCE

Archaeological evidence points to Paleolithic people in the Japanese archipelago at least around 30,000 years ago. Researchers still debate the details of how people first arrived – land bridges and coastal routes are both discussed – so it is better not to present a single migration path as certain.

This early period is also known as a pre-ceramic era because pottery technology was not yet part of the archaeological record the way it would be later.

13.) Jomon Period: Early Pottery Culture of Japan

Jomon culture dates back roughly 14,000+ years and is known for some of the world’s earliest pottery. Jomon cultural sites still preserve pottery artifacts and stone tools from that time, and the name itself is tied to the cord-marked pottery style associated with the period.

14.) After the Jomon Period, Came the Yayoi Period

After the Jomon period came the Yayoi period, generally placed in the first millennium BCE. Yayoi communities are associated with skilled weaving and craftwork, and especially with the spread of wet-rice agriculture.

Because people could farm rice more intensively, settlement patterns changed and populations grew compared with earlier hunter-gatherer ways of life.

15.) No-Melt Ice Cream!

Okay, the title is a little clickbaity – the ice cream will eventually melt – but in 2017 researchers in Japan publicized a novelty/research ice cream that reportedly held up for hours without melting the way ordinary soft-serve does. The discovery was tied to experiments with strawberry chemistry after the 2011 earthquake disrupted farming communities.

If you want a quick look at the 2017 story, there is a short video of the demo online.

16.) The Portuguese were the First Europeans to Visit Japan

The first Europeans to visit Japan are commonly dated to the Portuguese arrival in 1543 at Tanegashima (not the Port of Nagasaki). That visit helped open the Nanban trade period that lasted into the early 1600s.

During this period, Japanese and Portuguese traders exchanged goods, and new technologies and cultural practices – including European firearms and ships – entered Japan. Another surprising detail from this era is that Portuguese cooking influence is often linked to the later popularity of tempura.

17.) Japan Had a Long Period of Restricted Contact with the Outside World

Because European influence was growing after first contact in 1543, Tokugawa authorities sharply limited overseas travel and foreign contact under policies associated with the Sakoku Edict of 1635. This was not absolute isolation from the entire world: trade and diplomacy continued through controlled channels that included Nagasaki, Tsushima, Ryukyu, and Ainu networks. The restricted-contact era lasted more than 200 years.

18.) A Highway that Goes Through a Building

Yes, you read that right! In Osaka, the Hanshin Expressway goes directly through the Gate Tower Building’s 5th, 6th, and 7th floors. In reality, the workers in the building don’t really notice as the walls and floors of the building are soundproof and the highway doesn’t actually touch the building.

19.) Japan has a Word for Death by Overwork, “Karoshi”

One of the first things you’ll notice in Japan’s big cities is how intense the work culture can look from the outside – especially the morning rush of salarymen and salarywomen packing onto trains.

Japan even has a term, karoshi, that literally means death by overwork. In recent years, work-style reforms have introduced legal overtime limits in many cases, including labor-law changes that took effect around April 2019, so the long-hours culture is not unchanged from a decade ago.

20.) One Heck of a Healthy Diet

Traditional Japanese dietary patterns – often including rice, fish, vegetables, and relatively modest portions – are frequently discussed in conversations about health. That said, longevity is multifactorial. Diet can be one piece of the picture alongside walking, healthcare, and social factors, rather than a single direct cause.

21.) Japan Is the Only Country Whose Monarch Uses the Title Emperor

Japan is the only country whose monarch uses the title Emperor. Even though the emperor does not hold governing power and serves a largely symbolic role, the imperial household remains an important part of Japan’s traditions.

The current emperor is Naruhito, who ascended on May 1, 2019, after Emperor Akihito abdicated on April 30, 2019.

22.) Japan Remains One of the World’s Largest Economies

Japan remains one of the world’s largest economies. It is pretty incredible to see how far the country has come, especially given the devastation of WWII and the rebuilding that followed.

If you have driven anywhere recently, you already know one of the country’s best-known product exports: automobiles, with brands like Honda and Toyota everywhere on the road.

23.) A Banned Pokemon Episode

On December 16, 1997, an episode of Pokemon aired in Japan that used intense strobe lighting. Hundreds of viewers reported symptoms, and many received medical treatment. Some children had seizures. The incident led to a four-month broadcast hiatus and changes to animation broadcast standards in Japan.

24.) The Political Structure of Japan

Japan is commonly described as having eight regions and 47 prefectures. The prefecture system goes back to the Meiji Period (1868-1912), when it replaced the older lands controlled by the daimyo, the powerful feudal lords who ruled before Meiji reforms.

25.) Japan is a Country of Varying Climates

Since Japan geographically stretches from North to South for such a long distance, the climate in different areas of the country tends to vary by a good amount. The climate in some of the big cities like Tokyo ranges from a temperate to subtropical climate. This means hot summers and mild winters, and 4 different seasons.

On the other hand, the climate across the northern island of Hokkaido is much cooler. The summers are nice and mild, but in the winter the area gets a ton of snow and the temperature often drops below freezing.

26.) It is a Hiker’s Paradise

Hiking is probably not on most people’s minds when they come to Japan, but it actually has a huge collection of mountains and trails to hike. Plus, because of the geographical diversity of the country, there is a huge selection of different types of hikes to go on. You can challenge yourself both physically and mentally by hiking up the majestic Mount Fuji, hike a UNESCO-recognized series of pilgrimage routes, or go trekking on some of the trails in the Japanese Alps

27.) Mount Takao: A Natural Recreation Area Near Tokyo

If you’re spending time in Tokyo, you don’t need to go too far to get into the mountains. Mount Takao (高尾山, Takaosan) is an easy day trip from central Tokyo – roughly an hour from Shinjuku by train, depending on connections. Fares change over time, so verify current transport details before you go.

Once you arrive, you can hike up to the summit (close to 2,000 feet) or take the cable car partway. From the top you can see views toward Tokyo, and on clear days you can even see Mount Fuji.

28.) Japan Has a Long, Complex Coastline

Japan has a long, complex coastline – cliffs, hiking trails, sleepy coastal towns, and major fishing ports among them. Exact world rankings shift depending on how coastline length is measured, so the more durable point is the sheer variety of coastal landscapes packed into the archipelago.

29.) Kitayamazaki Cliffs: The Most Famous of them All

The Kitayamazaki Cliffs is a 5-mile section of the Rikuchu Coastline in Northern Iwate Prefecture that has 650-foot cliffs stretched along the 5-mile section. The area is so famous because in 1999 it received first place in the “natural resource: coast” category in the National Tourist Resource Evaluation conducted by the Japan Travel Bureau Foundation.

The best view of the coastline is from the Kitayamazaki Observatory, which has 3 different observation decks at different heights so you can get different views of the coast from one place.

30.) There are Epic Gorges in Japan

I definitely did not know this until I started researching, but Japan is home to several spectacular gorges that offer views of cliffs, forests, and nearby waterfalls. While you can go hiking in most of these gorges, at some of the other gorges, you can take a scenic boat ride or sightseeing train through them.

Some of the most famous gorges in Japan include Takachiho Gorge, Kurobe Gorge, and Geibikei Gorge.

31.) There are Massive Limestone Caves

As I have been saying, the geographical diversity in Japan is crazy! There is actually a huge amount of limestone caves strewn throughout the country and is a great way to escape the summer heat or winter cold since the temperature in the caves stays constant year-round.

These caves were formed millions of years ago and feature natural formations like limestone pools, streams, and underground waterfalls. A couple of the most famous limestone caves in Japan are Akiyoshido Cave, Abukumado Cave, and Ryusendo Cave.

32.) You Can Find Beautiful Marshland in the Country

Japan has some of the most beautiful marshlands in the world that are especially popular to visit during the autumn months when the leaves change color. Hopefully, one day I can visit these marshlands during the fall colors as you get to see not only the leaves change colors, but also the grass in the marshland. A few of the most popular marshlands in Japan are Oze National Park, Senjogahara Marshland, and Kushiro Marshland.

33.) Nachi – Japan’s Tallest Uninterrupted Single-Drop Waterfall

Standing at 133 meters, Nachi Falls is Japan’s tallest uninterrupted single-drop waterfall. It is located in Nachikatsuura, Wakayama Prefecture, ranked among Japan’s most famous waterfalls, and sits along the Kumano Kodo pilgrimage routes mentioned in #26.

34.) The 2003 Pet Boom of Japan

Starting around the early 2000s, pets became more and more visible in everyday Japanese life – a period often described as a pet boom. Exact pet-versus-children comparisons and shelter statistics from that era are easy to overstate or misread out of context, so the safer takeaway is historical: companion animals became a much bigger part of urban life in the 2000s than they had been a generation earlier.

35.) Japanese Trains are Extremely Punctual

Trains in Japan are so punctual that it’s scary! At the same time, it makes me wonder in awe how they do it because there are so many different train lines that run throughout the country on a given day. In fact, in 2017, the Tsukuba Express line between Tokyo and Tsukuba made global headlines when the management of the train line apologized publicly for leaving the station 20 seconds early.

36.) Japan Has Famous Sand Dunes

Yes – Japan has sand dunes. The best-known are the Tottori Sand Dunes, one of Japan’s largest dune landscapes (about 9 miles long and 1.5 miles wide). They are not Japan’s only dunes, but they are the ones most visitors hear about.

Over two million visitors come annually to explore the area. Activities include sandboarding, paragliding, camel rides, a museum, and a chairlift up to an observation deck.

37.) Hikikomori – A Population Who has Withdrawn from Society

Hikikomori refers to people living in prolonged social withdrawal, often staying home for six months or longer. A 2022 Cabinet Office survey was widely reported as estimating roughly 1.46 million people ages 15-64 in Japan living in that kind of prolonged withdrawal. The experience is not limited to one gender stereotype, and similar patterns have been discussed in other countries as well.

38.) There was a Ban on Dancing After Midnight

Japan’s postwar Entertainment Business Control Law dates to 1948 and long restricted dancing in many clubs and venues late at night. Those restrictions were revised in 2015 and relaxed under new rules from 2016, ending the old after-midnight dancing ban era that visitors used to hear about.

39.) The Country has a Huge Number of Onsens (Hot Springs)

Because of Japan’s volcanic geology, the country has thousands of onsen (hot spring) sites around the islands. The geology, bathing etiquette, and ryokan culture are a huge part of travel in Japan.

I was lucky enough to stay at a ryokan in the Lake Kawaguchiko area and experience a private onsen there. Hopefully I can make it to other onsens on future visits – Hakone has been high on my list. (I’m skipping medical claims about what spring water “treats”; enjoy the experience, and talk to a doctor about health conditions.)

40.) Dogo Onsen Has a History Going Back Roughly 3,000 Years

Dogo Onsen on Shikoku is often described as one of Japan’s oldest hot springs, with a history going back roughly 3,000 years rather than an uncontested single “oldest” title. For Miyazaki fans, it is often said to have inspired the bathhouse in Spirited Away.

In 1994, Dogo Onsen Honkan became the first public bathhouse in Japan designated an Important Cultural Property, and in 2009 it received three stars in the Michelin Green Guide for Japan. The main Honkan fully reopened on July 11, 2024 after renovation work.

41.) Onsens in Japan were Discovered by Ancient Hunters

According to legend, hunters and warriors discovered many Japanese hot springs by following wounded animals that sought out the warm water. These animal-discovery stories are folklore rather than verified history, but they are a classic part of how onsen origin tales get told.

42.) Japan’s Mountainous Terrain Limits Pastureland

This is not all that surprising once you picture Japan’s geography, yet it still surprised me at first. Because the country is so mountainous, forested, and densely developed in the cities, pastures and grassland make up only a small share of the land.

43.) Japan’s Terrain Also Limits Agricultural Land

Related to the above, Japan’s mountain ranges and volcanoes leave limited room for farming. Most land that can be farmed is found along coasts or in river valleys between the mountains.

44.) The Shinano River is the Longest River in Japan

While there are many many rivers in Japan, most of them are shorter. The Shinano River on the other hand at 228 miles, is the longest in the country, which is located on Honshu, the main island in Japan. At a length of 228 miles, this river has about the same length as the Severn River of England, which is the longest river in Great Britain.

The river’s source is from the Japanese Alps in Mount Kobushi and from there it flows into the Sea of Japan.

45.) Lake Biwa – The Largest Lake in Japan

The largest lake in Japan is Lake Biwa. A freshwater lake located in Shiga Prefecture and just to the northeast of Kyoto. The lake covers an area of 258.8 square miles which is huge when talking about Japan, but when you compare Lake Biwa to other large lakes in the world, it’s actually quite small.

For example, the Great Salt Lake in Utah covers an area of 1,800 square miles and the Great Lake Superior covers a whopping area of 31,700 square miles!

The name of Lake Biwa is believed to have been established in the Edo period because of how closely it looked like the Japanese instrument called the Biwa.

46.) Japan Has a Very Low Unemployment Rate

Although work-life balance in Japan is a complicated topic, the country does have a very low unemployment rate by international standards. Japan’s Statistics Bureau reported 2.4% seasonally adjusted unemployment in July 2026. Country ranking comparisons change quickly, so the durable point is simply how low the rate has stayed in recent years.

47.) Isewan Typhoon – The Most Devastating Typhoon to Hit Japan

Every year many typhoons do hit Japan, but the most devastating in the country’s history is the Isewan Typhoon of 1959 which cost more than 5,000 lives. The typhoon is also known as Super Typhoon Vera and it is actually the third most deadly natural disaster in Japan during the 20th century.

Only two other natural disasters, the Great Kanto Earthquake in 1923 and the Great Hanshin-Awaji Earthquake claimed more lives.

48.) Great East Japan Earthquake – Most Powerful Earthquake to Hit Japan

The Great East Japan Earthquake – also known as the Tohoku earthquake and tsunami – struck on March 11, 2011, at magnitude 9.0. It was Japan’s strongest recorded earthquake by magnitude and generated a devastating tsunami. Damage estimates ran into the hundreds of billions of dollars, and more than 120,000 buildings were destroyed.

49.) Oldest Company in the World Until 2006

Kongo Gumi Co. Ltd, an Osaka founded and based construction company that specialized in building Buddhist temples was actually the oldest running company with over 1,400 years of history before it was purchased and absorbed by the Takamatsu Construction Group in 2006.

It’s crazy to think about, but the company was founded in the year 578 AD and took part in building some of the most famous buildings in the Osaka and Kyoto area, including Osaka Castle and Hōryū-ji in Nara. 

50.) Japan has the Shindo Scale for Measuring the Strength of Earthquakes

Another interesting earthquake detail in Japan is how intensity is reported. While many parts of the world lead with magnitude, Japan also uses the JMA seismic intensity scale known as shindo.

Magnitude describes the overall size of the earthquake. Shindo describes how strongly the shaking was felt at a location. They answer different questions, which is why Japanese news reports often pair both.

51.) The Land of Vending Machines

I’m not exaggerating when I say you can buy an incredible range of things from vending machines in Japan – drinks, snacks, and plenty of surprises. Japan still has millions of vending machines nationwide. Exact machine counts and per-person ratios bounce around depending on the year and what gets counted, so I am leaving the old “23 per person / 5 million” figures behind.

52.) Japan Legalized Integrated-Resort Casinos in 2018

Integrated-resort casino gambling was legalized in Japan in 2018. That did not mean casinos opened overnight. MGM Osaka is targeted to open around autumn 2030. Meanwhile, pachinko has long occupied a gray-area entertainment niche that looks a little like the world’s most intense pinball, with prize-exchange workarounds historically used around gambling restrictions.

53.) There is A lot of Fake Food Being Sold in Japan

Outside almost every Japanese restaurant, you will find a fake version of the food served by that restaurant or even an animated version of dishes served at the restaurant. Well, you have to buy these fake food items somewhere, right?

That place is Kappabashi Street in Tokyo and here you can find everything you would need as a restaurateur including pots, pans, utensils, knives, and yes, a huge selection of fake food!

54.) Japan’s Population Is Shrinking as Fertility Stays Very Low

Japan’s population is shrinking, and fertility remains very low. Japan’s 2025 census preliminary result was about 123.05 million people. In 2024 there were 686,173 births and a total fertility rate of 1.15. Those numbers will keep shifting, but the direction has been clear for years.

55.) Okinawa’s Place in Longevity Research

Okinawa has an important place in longevity research and Blue Zones discussions, with a well-known historical reputation for healthy aging and community ties. I am not claiming it currently has Japan’s single highest longevity figures without fresh prefecture-by-prefecture evidence – the durable point is Okinawa’s outsized role in how the world talks about long life.

56.) Slurping Noodles Is Common in Many Noodle Shops

One of the first things parents tell kids is to chew with their mouths closed. In many Japanese noodle shops, though, slurping ramen, soba, or udon is socially normal and acceptable. It is neither required nor a universal “sign of appreciation,” and etiquette still depends on the setting.

Soba used to be common street food, and one explanation for slurping is that people were grabbing a quick bite at soba carts. Some people also say it helps the noodles taste better.

57.) Seafood Remains Central to Japanese Cuisine

Seafood remains central to Japanese cuisine, from everyday fish dishes to market culture and sushi. At the same time, per-capita seafood consumption has declined over recent decades, so older “share of world harvest” rankings are not the best way to describe the story now.

58.) Inemuri: Sleeping While Present

This does not mean naps are broadly encouraged as official workplace policy. Inemuri – sleeping while still being present – can be socially tolerated in some contexts, including on trains or in moments when someone has clearly pushed through exhaustion. Japanese workers are often described as getting relatively little sleep, which is part of why public napping is such a familiar sight.

59.) People Love Having Christmas Dinner at KFC

It sounds surprising at first, but Christmas fried chicken from KFC became a modern holiday tradition in Japan after 1970s marketing popularized the idea. Takeshi Okawara, manager of the first KFC in Japan, is widely credited with helping invent that Christmas barrel campaign. At the time, Christmas was not a major home tradition for most people, and the marketing filled the gap.

60.) Japan is one of the Safest Countries in the World

Japan has a reputation for relatively low crime, and that matches how it has felt on our trips. We have walked around at all hours and never felt unsafe. Hard safety-index scores change with each data refresh, so I am leaving the old Numbeo number out and sticking with the firsthand impression plus the broader reputation.

61.) No Shoes Allowed Inside

One thing is for sure. Before entering any Japanese house, you will most likely be asked to remove your shoes and will be given a clean pair of indoor slippers to wear. Like other Asian countries, it is considered customary and much more hygienic to remove your shoes before entering someone’s house.

What makes Japan unique is that you’ll also see this happen at restaurants and even in some workplaces. In Japan, it is deemed rude to wear shoes inside a house.    

62.) There are Musical Toilets in Japan

One of the most unique things in Japan are the high tech toilets you will find in the country. Not only do these toilets automatically warm the seat up for you, but they also wash your bottom and can play music to drown out any unwanted noise! When we were in Japan almost all of the toilets were these high tech toilet types so you have a good chance of running into one.

Not all of them were able to play music, so I wish you the best of luck in finding one!

63.) Square Watermelons in Japan

Leave it to Japan to turn fruit into an art form. Square watermelons are grown primarily as decorative or luxury produce and gifts. Prices vary widely, so I am skipping a hard dollar figure. Growers have also experimented with heart-shaped melons and other novelty forms.

64.) There is a Penis Festival in Japan

Yes, you read that right. The first Sunday in April every year is the Kanamara Matsuri festival which is also known as the Penis Festival and also known as the Festival of the Steel Phallus.

Legend has it that a very very jealous demon used to live inside the vagina of a goddess who bit off the penises of her first two husbands. The next guy who tried to win the goddess over did not let the story of the demon scare him away. This guy was a blacksmith and his plan was to trick the demon by forging a steel phallus.

It worked!

When the demon went to bite off the blacksmith’s penis, it got a mouth full of steel and the demon’s teeth were broken off. The blacksmith eventually won the goddess over and the rest is history.

65.) Japan Has Specialty Raw-Meat Dishes

Most people know Japan for raw fish in sushi and sashimi, but there are also regional and specialty raw-meat dishes such as basashi (horse). Raw chicken (torisashi) appears at some specialized establishments, though it carries real food-safety risk. “Extremely common” overstates how everyday these dishes are for most people.

66.) The Number 4 is Unlucky in Japan

Just like other countries in Asia, the number 4 is considered unlucky in Japan because the pronunciation is very similar to the word death. In Japan, the number 4 can be read “yon (よん) ” or “shi (し)”. The Japanese Kanji for death is “shi (死)”, so you can probably tell how close they are to each other now.

67.) Nôgaku Theater – An Intangible Cultural Heritage by UNESCO

Nogaku – Noh and Kyogen – is recognized by UNESCO as intangible cultural heritage. Its roots trace back to earlier performing traditions; Noh and Kyogen developed into the classical form associated especially with the 14th-15th centuries. Nogaku later influenced Kabuki and Japanese puppet theater.

68.) Specially Grown Fruit is Considered a Luxurious Gift in Japan

Japan takes fruit seriously. Ordinary supermarket fruit is reasonably priced, but specialty fruit – carefully grown, graded, and gifted – can be extremely expensive. Record-setting auction prices for trophy melons or grapes are not the same thing as everyday retail, so do not assume normal fruit routinely costs thousands of dollars.

Some of the famous specialty names include Ruby Roman grapes, Yubari melons, and oversized prize strawberries.

69.) Black Cats and Good Fortune in Japan

In many countries a black cat is considered unlucky, but Japanese folklore is more mixed and often kinder. A safer example than a universal “black cat crossing your path” rule is the black Maneki-Neko, which in some traditions is associated with protection and good fortune. Maneki-Neko come in many colors, including black.

70.) Cuddle Cafes Are a Niche Tokyo Phenomenon

Cuddle cafes became a niche Tokyo phenomenon for people seeking low-pressure physical company – paid cuddling time, with optional add-ons like hand-holding or conversation. They are best understood as a specific urban service trend, not a common national pastime.

71.) ASIMO – Honda’s Famous Humanoid Robot

Japan is famous for robotics, and one of the best-known humanoid robots was Honda’s ASIMO. It even played football with President Obama and danced for Chancellor Angela Merkel.

Miraikan in Tokyo ended regular ASIMO demonstrations on March 31, 2022 after about 20 years. Honda had already wound down the ASIMO program as robotics competition moved on.

72.) Kids Get Taught How to Clean in School

Yes, for all of you who struggle to make your bed in the morning, every day in Japanese schools, the kids and the teachers will clean their school together! The cleaning time in school is called “osouji jikan” お掃除時間 and is a time when everyone works together to help keep the school clean. How cool is that!

73.) The Unique McDonald’s Menu in Japan

When I’m in Japan, McDonald’s is rarely my first choice with so much other food around. If you do get the craving, the localized menu is genuinely fun. Japan has roughly 3,000 McDonald’s restaurants and plenty of Japan-only items – think teriyaki burgers, shrimp options, and rotating novelty sides.

74.) How Sushi Evolved Into the Dish We Know Today

Modern sushi did not simply “exist since the 2nd century AD.” Sushi evolved from older preserved and fermented fish-and-rice traditions, while Edo-style nigiri emerged in Japan in the 19th century. In Japanese, sushi refers to the seasoned rice as much as to the fish.

Earlier forms often used rice mainly to preserve fish, and the rice was not always eaten. By the Edo period, people were eating fish and rice together in a way much closer to the sushi we know now.

75.) The World Famous Kobe Beef

Kobe beef is famous worldwide for its marbling and flavor. Official Kobe Beef material says beer and massages are not standard production practices, so treat those stories as myth rather than normal ranch routine.

Real Kobe beef comes from Tajima lineage cattle raised and slaughtered in Hyogo Prefecture under strict grading rules. Remember: all Kobe is wagyu, but not all wagyu is Kobe.

76.) The Shortest Poetry in the World was Created Here

Haiku developed in Japan and is often called the world’s shortest poetic form. Traditional Japanese haiku use 17 morae in a 5-7-5 pattern. English haiku often approximate this with syllables, but they do not have to match the Japanese mora count exactly. Haiku is as much a way of noticing the world as it is a verse form.

77.) Japan Has Produced Many Nobel Laureates

Japan has produced many Nobel laureates, particularly in physics, chemistry, and medicine. Exact counts and regional rankings change as new prizes are awarded, so the durable point is Japan’s outsized scientific contribution rather than a frozen leaderboard number.

78.) Japan and Russia Never Signed a Formal WWII Peace Treaty

Japan and Russia are not in an active state of war, but they never signed a formal WWII peace treaty. The sticking point remains the territorial dispute over the Kuril Islands / Northern Territories. “Still at war” overstates the situation; “no formal peace treaty” is the accurate framing.

79.) The Crazy Flavors of Kit Kats You Can Find in Japan

In most countries, you wouldn’t think twice about Kit Kats, but not in Japan! In Japan, your regular Kit Kat candy bars are available in crazy flavors like grilled corn, Earl grey tea, or camembert.

They are also considered a top gift for a student during the entrance exam. Ever since traveling to Japan for the first time, I’ve always made it a point to try out as many different flavors of these Kit Kats as I can. So far my favorite flavors have to be the Cherry Blossom or Azuki Bean flavor!

80.) 3rd Biggest Producer of Cars in the World

Japan is one of the world’s largest automobile producers. Toyota is among the largest automakers on the planet.

Sakichi Toyoda invented the Type G loom in 1924; Toyoda Automatic Loom Works was founded in 1926; the automotive division began in 1933; and Toyota Motor Co. was established in 1937, with Kiichiro Toyoda leading the automotive business.

81.) The Land of Hello Kitty

Hello Kitty was created in Japan in 1974 and quickly grew from a coin-purse design into a global character business with tens of thousands of products. Franchise revenue rankings change over time, so I’m leaving the old “second-highest-grossing of all time” claim out and sticking with the 1970s origin story.

82.) Japanese Macaques are Part of Fables

If you have ever heard the famous maxim of the three wise monkeys “See no evil, hear no evil, speak no evil” or have seen the maxim in the form of carvings or statues, it’s origin is actually from Japan.

The original three wise monkeys is a carving over a door of the famous Tōshō-gū Shrine in Nikko, Japan. The monkeys themselves are the common Japanese Macaque, which is the same as the snow monkey which you would see bathing in the hot springs of Nagano!

83.) Sumo Wrestling: A History Of 1500 Years

In Japan, Sumo Wrestling has a history of more than 1,500 years. The wrestlers here have an average weight of 300 pounds and are trained in the Heya rooms handled by former champions.

The younger wrestlers are conventionally required to clean and care for the veteran wrestlers. The most interesting part to me about Sumo Wrestling is that it’s actually a Shinto ritual that is supposed to help bring a bountiful harvest and honor the spirits!

84.) Japan has an Island of Rabbits

I didn’t believe there could be an island full of rabbits until I visited myself. Okunoshima in Hiroshima Prefecture really is overrun with friendly rabbits.

During WWII the island was a poison-gas manufacturing site, but today’s rabbits do not have a single proven origin story. JNTO notes conflicting accounts; a common version says schoolchildren released eight rabbits in 1971. Present the origin as uncertain. What I can say firsthand is that the rabbits are used to people – just look at the furry faces we hung out with while we were there.

85.) The Etiquette of Bowing

In Japan, bowing is a core form of social etiquette. A common teaching convention is roughly 15 degrees for an informal/slight bow, 30 degrees for a polite/formal bow, and 45 degrees for deeper respect or apology. These are guidelines, not rigid rules for every situation.

86.) The Interesting and Short-Lived Ganguro Fashion Trend

Ganguro was a striking Japanese fashion trend from the mid-1990s into the 2000s, especially visible in Shibuya and Ikebukuro. Young women darkened their skin, bleached their hair toward blonde/orange, and used bold makeup. It is best remembered as a historical street-fashion moment, not a current mainstream style with one exact end date.

87.) The Shortest Escalator in the World

Japan has a Guinness-recognized shortest escalator at More’s department store in Kawasaki: 83.4 cm high, with five steps.

88.) Yaeba Was a Notable Beauty Trend

Yaeba – a snaggletooth look – was a notable beauty trend especially in the 2000s and early 2010s, popular enough that some clinics offered cosmetic versions. It is not a universal current preference for crooked teeth across Japan.

89.) Japan has the Busiest Train Station in the World

Tokyo’s Shinjuku Station is widely recognized as the world’s busiest railway station. Guinness lists about 2,704,703 average daily passenger throughput in 2022. Japan still dominates global lists of the busiest stations.

90.) Origin of the Name of “Japan”

In Japanese, the term Japan refers to Nihon or Nippon. This further refers to the Land of the Rising Sun’. The country was given this name as it was believed to be the first country to witness the rise of the sun since it was known to be located east of China.

91.) The Tale of Genji Is Often Called the World’s First Novel

The Tale of Genji, written by Murasaki Shikibu, is often described as the world’s first novel and remains one of the great works of Japanese literature. Some of its emotional force is traditionally linked to the loss of her husband.

The photo above is from our visit to Hirakata T-Site near Osaka – a natural stop if you love books while traveling in Kansai.

92.) Tsunokakushi – Bride’s Traditional Headdress for a Wedding

In traditional Shinto weddings, the bride may wear a rectangular cloth headdress called the tsunokakushi. Traditional symbolism is often explained as concealing the “horns” of jealousy or anger. That is a cultural metaphor, not a literal instruction that marriage requires submission.

93.) The Meaning of “Banzai”

Banzai literally means “ten thousand years” and is commonly used today as a celebratory cheer. You might hear it after a big sports win or before a team kicks off a major effort. Translating it simply as “hip hip hooray” loses the literal meaning, even if the social use can feel similar.

94.) The Subtle Art of Haragei

In much of the West, conversation tends to be direct. In Japan, haragei (“stomach art”) refers to implicit or nonverbal understanding – sensing what someone means without everything being spelled out.

That does not mean Japanese people “really do not like to say no” as a stereotype. Indirect refusals can appear in some contexts (“that will be difficult,” “I’ll try”), but communication styles vary by person and situation.

95.) Fugu – The Poisonous Blowfish

Fugu is a poisonous blowfish that is also a delicacy in Japan. I’ve thought about trying it ever since that Simpsons episode, but I still have not worked up the guts.

Preparation and licensing requirements vary by prefecture, but fugu handling is regulated because tetrodotoxin is dangerous. There is no single nationwide “three years of training” rule that covers every jurisdiction. It is also often said that the imperial family does not eat fugu.

96.) Ringing of the Bells on New Years Eve

Every New Year’s Eve, many Buddhist temples in Japan ring their bells 108 times in a ceremony called joya no kane (除夜の鐘). Exact timing and custom vary by temple – some begin before 11 p.m. and time the final strike for midnight – but the 108 strikes are the shared idea.

97.) Bugaku and Gagaku: Ancient Court Music and Dance Traditions

Bugaku is traditional imperial court dance, and gagaku is the music that accompanies it. They are among the world’s oldest continuously performed court music and dance traditions. Before WWII, these performances were largely reserved for elites; after the war they became more accessible to the public.

98.) Baseball is by Far the Most Popular Sport

Horace Wilson is traditionally credited with introducing baseball to Japanese students in 1872, though newer historical research indicates baseball was already being played in Japan by foreigners earlier. Since then it has become Japan’s most popular sport, producing MLB stars like Ichiro Suzuki, Hideki Matsui, and Hideo Nomo.

99.) Osaka Castle Used to Be Black and Gold

In its early days, Osaka Castle’s exterior was painted black, with gold and silver decoration inside. The castle complex has been destroyed and rebuilt more than once; the current main tower is a 1931 reconstruction and museum, with a white exterior. You can read more in our post about the wonderful museum inside Osaka Castle.

100.) Godzilla is in Shinjuku!

In Shinjuku, you can find the giant Godzilla head at Hotel Gracery / Toho Cinemas – a fun photo stop if you are a fan. There are other Godzilla statues around Tokyo too; I’m skipping “even bigger” comparisons unless the dimensions are directly verified.

Conclusion

If you’ve made it through all 100, hopefully at least a few of these surprised you. Japan is one of those places where the more time I spend there, the more there is to notice, from the huge historical and cultural traditions to tiny details of everyday life.

A few of these facts have changed since I first wrote this article in 2019, which is part of why I wanted to update it rather than let an old list sit untouched. I’ll keep revisiting it as the numbers and details change, while leaving the original travel photos and stories in place.

If you’ve been to Japan and have another fact we should know, leave it in the comments. A lot of the best additions to this article over the years have come from readers.
