Weird Facts About Japan

Japan is one of the most technologically and socially advanced nations on Earth, but the country is also known for its idiosyncratic culture and pastimes. Here are 43 weird facts about Japan.

 43. No-Pants Party

A Hakada Matsuri, also known as a "festival of minimal attire", quite accurately matches its description. In dozens of places throughout Japan, thousands of men and boys strip down to loincloths in hope of gaining luck for the year.


42. Hot Stuff

Japan has a centuries-old tradition of traditional bathhouses. But the Yunessun Spa Resort is no traditional spa—there you can soak in a green tea spa, a sake spa, a coffee spa, and even a ramen-noodle spa.

41. Nap time!

Napping on the job—called inemuri—is seen as a sign of being a hard worker in Japanese business culture. Some people even fake it!

40. Rent-a-Cuddle

The first “cuddle cafes” opened in Tokyo in 2014. Called Soine-ya (literally “sleep-together shop”), they allow male customers to sleep next to a woman for a fee.Requests of an intimate nature are not permitted, however, the menu offers alternatives such as "gazing at each other for a minute" or "brushing the girl's hair for three minutes" for 1,000 yen each.

39. Tan Tactics

Ganguro, which literally translates to “blackface,” is a recent trend in which women bleach their hair and wear facial makeup that approximates an exaggerated tan. This makeup doesn’t have the same meaning that it does in North American culture—instead, it’s a reaction to traditional beauty standards that require dark hair, pale skin, and understated makeup.

38. Gimme a Smile

Another unusual fashion trend is yaeba, in which young Japanese women have artificially uneven teeth installed to imitate a naturally snaggle-toothed smile.

37. A Visit From Colonel Santa

Kentucky Fried Chicken is a common Christmas tradition in Japan. An estimated 3.6 million Japanese families eat KFC as a holiday tradition, and daily sales in December can be 10 times higher than average. The KFC Christmas dinner special has to be ordered weeks in advance. The tradition started when an executive, after hearing expats wish for turkey to celebrate the holiday, began a “Kentucky for Christmas” marketing campaign—and it immediately took off.

36. Shake, Rattle & Roll

About 1,500 earthquakes hit Japan every year, and minor tremors occur on a daily basis. The nation sits on top of four tectonic plates, which is also the reason the country has so much volcanic activity.

35. A Grand Old Time

Japan’s population is aging rapidly. In 2012, there were more than 50,000 people over the age of 100. It’s estimated that by 2100, the elderly population of Tokyo—people older than 65—will equal the working age population—people between the ages of 15 and 64.

34. All in the Family

Japan is the home of the world’s oldest continually operating independent company. Kongō Gumi Co., Ltd, was a construction company that operated for over 1,400 years, until being absorbed by another company in 2006. Since its founding in the year 578, the company was run by members of the same family for 40 generations.

32. Cleaning With Class

As part of their school day, Japanese students clean their schools, in a tradition called o-soji. Time is set aside every day for students to tidy up classrooms, mop floors, and clean bathrooms. A few times a year, they also clean up in the neighborhood around the school. The practice teaches students to help others and respect their surroundings.

31. Going Down

There's some things you just only ever see in Japan. This is one of 'em.

The world’s shortest escalator is the one in the basement of the More’s Department Store in the city of Kawasaki. It’s 33 inches tall and has only five steps.

30. Father Figure

Adults are more commonly adopted than children are in Japan. Over 90% of the people adopted in 2011 were men between the ages of 20 and 30. These adoptions are often a way for a family to secure a heir or pass down a business. Adult adoption is also utilized as a legitimate alternative to marriages of the same gender, not formally acknowledged in Japan.

29. Yes You Can

A chain of restaurants called Mr. Kanso only serves food that comes out of a can. At the more than 40 locations nationwide, diners can choose from more than 300 dishes, from cuisines from around the world. Options include salad in a tin from France and walrus curry.

27. Homebound

Roughly 541,000 Japanese between the ages of 15 and 39, most of whom are male, live lives of total seclusion. These young people are called hikikomori. The Japanese Health, Labor, and Welfare Ministry defines the term, which was coined in the 1980s, as people who have not left their homes or interacted with others for at least six months. Support centers and virtual high schools have been established to help the hikikomori, whose condition is thought to stem from psychological issues as well as the high expectations Japanese society places on men.

26. Final Forest

In the shadow of Mt. Fuji, the Aokigahara forest is recognized as the world's second most frequented place for people seeking to end their lives, with the Golden Gate Bridge being the first. About 70 bodies are found in the woods every year, but it’s assumed that many bodies are lost in the forest. The location regained its popularity through the novel Kuroai Jukai, which concludes with a romanticized joint fatal act by the lead characters. Japanese authorities have ceased publicizing exact casualty numbers to prevent the forest from becoming a more frequently visited location for self-harm incidents.

25. A Land of Islands

The nation of Japan is made up of over 6,000 islands. The four largest are Hokkaido, Honshu, Shikoku, and Kyushu. Around 400 of these islands are inhabited.

24. On Track

Japanese trains are among the most punctual in the world. The average delay on the Tōkaidō Shinkansen, the most heavily traveled high-speed rail line in the world, is about half a minute. Trains are expected to be so punctual that if a train is five minutes late, the railway company may issue official delay certificates, to provide proof for employers and appointments. If a train is delayed for an hour or more, it may make the newspaper.

23. Pet Paternity

Japan has more pets than children. The country has an estimated 22 million pets, but only 16.6 million children under the age of 15.

22. Please Refrain, We're Japanese

According to the director of Japan’s Family Planning Research Center, the declining birthrate in Japan is largely due to a lack of interest in romantic physical activities. Almost half of married couples are intimate less than once a month, and 32% of young men dislike these intimate encounters because they fear failure and rejection by women. 60% of women in their mid- to late-20s are single, and 70% of unmarried women are not in a steady relationship. Marriage is still thought of as a requirement for having children—only 2% of Japanese children are born out of wedlock.

21. Stuck in the Middle With You

Technically speaking, WWII isn’t over. Despite being drafted in 1945, Moscow and Tokyo never endorsed the peace agreement that would have officially concluded the hostilities. The animosity between the two countries comes from a territorial dispute over the Kuril Islands, an island chain equidistant between the two nations, which Russia invaded in 1945 and continues to occupy. Today, the 30,000 Russian citizens on the island chain exist in a state of perpetual preparedness for conflict, with ballistic missiles directed towards Japan.

20. Char-Hazard

After a particularly intense episode of the anime series Pokémon that aired December 16, 1997, 685 Japanese children were hospitalized for headaches, dizziness, nausea, and even seizures caused by the show’s repetitive visual effects. After the incident, labeled the “Pokémon Shock,” the show went into a four-month hiatus, and the episode was not broadcast again worldwide—but some viewers also had seizures when the offending scenes were shown on news reports about the incident.

19. Chopped Up

Japan uses around 24 billion pairs of disposable chopsticks each year; almost 200 pairs per person per year. In Japanese cultural etiquette, crossing chopsticks on a table is seen as a negative omen, and sticking them vertically into a bowl of rice is a practice typically reserved for funerals.

17. Island Hopping

The island of Ōkunoshima is known as “Rabbit Island". Thousands of travellers come every year to visit the wild rabbits, who are so friendly they will jump up into your lap. This bunny paradise has a dark origin, though—the rabbits were originally brought to the island during WWII as test subjects for a deadly poison.

16. Norway’s New Nigiri

Japan is known worldwide as the land of sushi. However, one of the most popular kinds of sushi isn’t Japanese in origin. A Norwegian diplomat introduced salmon sushi to the Japanese in the 80s to sell his country’s own fish. Before then, the Japanese didn’t eat salmon raw—it was usually grilled or dried. Even then, salmon sushi didn’t really catch on until the mid-90s.

15. Where the Streets Have No Name

Most Japanese streets don’t have names. The system used for postal addresses is complex and idiosyncratic, starting with the prefecture (kind of like a state), then the city or municipality, the district, and then the block (for urban addresses) or the land number (in rural locations). To give directions to a location, most people give landmarks and subway stations. Many businesses include maps on their business cards.

6. Break Me Off a Piece

There have been more than 300 different Kit Kat flavors in Japan, including soy sauce, “European cheese,” and wasabi. Some of them are limited or regional editions.

Food scientists in Japan have recently invented ice cream bars that do not melt.

3. That’s How He Rolls

Sushi-chain owner Kiyoshi Kimura, known as Japan’s Tuna King, recently paid $600,000 for a 467 lb Bluefin tuna at the famous Tsukiji fish auction. Based on the auction price, a single piece of sushi from this fish would cost about $85. This was not Kimura's most expensive fish, though—the distinction goes to the $1.8 million fish he bought in 2013.

2. It’s Not Just the Food

Japan loves over-the-top theme restaurants. Along with an Alice in Wonderland themed restaurant, you can visit the Kabukicho Robot Restaurant—where the sexy robots make it resemble an automated gentlemen’s club—the underground lair of the Vampire Café, and Alcatraz ER, which is made to look like a mental institution from a horror film.

1. That’s Right, “Steel Phallus”

Each spring, the Shinto celebration Kanamara Matsuri—the Festival of the Steel Phallus—is held at the Kanayama Shrine. The festival celebrates the legend of a metal phallus that was constructed to prevent a demon that had hidden in a young woman's intimate area, spoiling her wedding night. The shrine was a popular site for sex workers, who prayed for protection from sexually transmitted infections. Today, the festival is used to raise money for HIV research.
