Interesting facts about Japan

Culture & Society

  • Japan has the highest life expectancy in the world, nominally surpassed by tiny city-states like Andorra and Macau, but by no other proper nation. Japanese people live in average 4 years longer than US citizens, 3 years longer than the Germans, the Belgians or the Brits, 2 years more than the Italians and 1 year longer than the French.
  • Japan has by far the highest percentage of centenarians of any country. There are now over 55,000 Japanese people over 100 years old, more than in the USA which is 2.5 times more populous than Japan.
  • Working hard is one of the most highly respected virtue in Japan. White-collar employees are often expected to pull an all nighter to finish important projects. Sleeping at work is seen as acceptable as it is viewed as exhaustion from dedication to one's job. Japanese is the only language that has a word for "death from overwork": Karōshi (過労死).
  • Japanese trains are possibly the world's most punctual. The average delay on the Tokaido Shinkansen in 2012 was only 36 seconds.
  • Japan is one of the safest and least violent country in the world, along with Iceland. The country has as few as two gun-related homicides a year.
  • Over 90% of mobile phones in Japan are waterproof, mostly because Japanese women like use them while having a bath, while younger men find it handy to use them in the shower.
  • There are 12 million pets in Japan, more than the number of children under 12 years old.
  • There are many pet hotels in Japan where cat and dog owners can leave their loved ones for a few hours or a few days while they are away. Private suite rooms can cost up to ¥15,000 (~$150) per day, as much as a luxury hotel for humans.
  • There is a Cat Café in Tokyo where customers pay ¥800 yen (~US$8) an hour to hang out with cats.
  • English is the only foreign language taught in public Japanese schools.
  • There are tens of thousands of English words used daily in modern Japanese (often not understood by the older generation), and the number keeps growing fast year after year.
  • Japanese farmers grow square watermelons in boxes so as to improve space efficiency in small refrigerators. They were invented by the graphic designer Tomoyuki Ono in 1978 and presented in a gallery in Ginza. Their uniqueness and popularity quickly led to an increase in prices and they now cost two to three times more than regular watermelons. Other watermelon shapes have since been introduced, such as hearts and pyramids.
  • There are over 5 million vending machines in Japan, which is about one machine for every twenty-three people - the world's highest number per capita. Japanese vending machines do not sell just snacks and drinks, but all sorts of products from Buddhist charms to women's underwear, but also beer and cigarettes.
  • Contrarily to most Western countries, black cats are considered to bring good luck in Japan. It is also the case in Britain and Ireland.
  • From 1948 to 2015 late-night dancing (after midnight) was illegal in Japan in venues without a special 'dance licence'.
  • People with tattoos are prohibited from entering Japanese hot springs and public bathhouses. This is because of the association of tattoos with the Yakuza, the Japanese organized crime syndicates.
  • Because of the ageing of the Japanese population and the low birth rate, the sale of adult diapers (nappies) has started outselling that of baby diapers since 2014.
  • Japanese people very rarely adopt children outside their extended family. In fact, 98% of all adoptions in Japan are of male adults, a practice that goes back to the 13th century and which was developed as a mechanism for families to extend their family name, estate and ancestry without an unwieldy reliance on blood lines.
  • Sleep statistics from smartphone apps have shown that people in Japan sleep less than any other country, usually under 6 hours per night.
  • Over one million Japanese (mostly male) adolescents or adults suffer from acute social withdrawal and lock themselves up in their bedrooms for months or years. They are known as hikikomori (lit. "pulling inward") and many of them may suffer from autism spectrum disorders.
  • The small island of Ōkunoshima, in the Inland Sea of Japan, is populated by hundreds of friendly wild rabbits that like to chase tourists for treats. The island has a darker past though. It is where Japan produced poison gas for the chemical warfare that was carried out in China during World War II.
  • Sushi is one of the oldest Japanese dishes, with a history going back to the 8th century. It was however first developed in Southeast Asia long before that, then spread to south China and eventually to Japan. Modern Japanese sushi and sashimi use over one hundred kinds of fish and seafood, but oddly enough it was the Norwegians who first thought of using salmon for sushi, and introduced the concept to Japan in the early 1980.
  • Mount Mihara, an active volcano on the isle of Izu Ōshima, near Mount Fuji, is the place where the Japanese government imprisoned Godzilla in the movie The Return of Godzilla. The vantage point near the top of the crater made it a popular spot for committing suicide, with thousands of people jumping to their death since the 1920's (over 600 in 1936 alone). A fence was eventually erected around the base of the volcano to curb the number of suicides.
  • Japanese are obsessed about not causing trouble to other members of society and expect others to behave in a similar fashion. For example, if someone commits suicide by jumping in front of a train, the family of the deceased will be charged a disruption fee.

History & Genetics

  • Japan has the oldest surviving monarchy in the world. The first historical emperor of Japan was Ojin, reigning from year 270 to 310, and deified as Hachiman. Legend has it that the very first emperor was Jinmu, who would have reigned 1000 years earlier. This is very unlikely though, for Japan did not become an agricultural and sedentary society before 300 BCE (and only then in western Japan).
  • Japan's national anthem, Kimi Ga Yo (君が代), is the world's oldest anthem, although it was only officially recognised as such in 1999. It is based on a 9th century poem.
  • The old Japanese language was a blend of ancient Korean and Jomon languages (distantly related to modern Okinawan and Ainu). Since the 6th century, Chinese characters (and the words that go with them) were imported into the language, and now amount to approximately half of the vocabulary in Japanese.
  • Genetic studies have revelaved that approximately 60% of Japanese gene pool comes from Korea and China, and 40% from the Stone Age inhabitants of Japan, the Jomon people (from whom the modern Ainu of the direct descendants). Nevertheless a northern Han Chinese from Beijing is genetically closer to a Japanese than to a southern Han Chinese from Canton.
  • Japan annexed Okinawa and Taiwan in 1895, then Korea in 1910, and kept them as part of the territory of the Japanese Empire until 1945. Okinawa still belongs to Japan.
  • The first extensive use of the rickshaw for transportation started in Japan from the 1870's. It later spread to the rest of East Asia and South Asia, where the motorized version is still very popular. The rickshaw is, however, not a Japanese invention. Some claim that it was invented by the American blacksmith Albert Tolman in 1848. Others attribute it to Jonathan Scobie, an American missionary to Japan, who invented it in 1869 to transport his invalid wife through the streets of Yokohama.
  • Fortune cookies are not a Chinese invention, but a Japanese one going back to 19th-century Kyōto and linked to the tradition of omikuji. Fortune cookies have since become very popular in the USA, especially in Chinese restaurants, hence its false association with China. The first American version of the cookie was introduced around 1900 by Makoto Hagiwara of Golden Gate Park's Japanese Tea Garden in San Francisco.
  • Chazuke used to be a typical dish of the lower classes in the Edo era. People would add green tea on a bowl of cold rice in chaya (teahouse) along the road. This was considered a full meal by those who couldn't afford fish or even vegetables.
  • There are 54 pagodas in Japan. The official top three pagodas (日本三名塔) are those of the Daigo-ji Temple in Kyōto, the Hōryū-ji Temple in Nara, and the Rurikō-ji Temple in Yamaguchi.
  • In the 1930's and during World War II, the Japanese government helped tens of thousands of Jewish refugees to resettle to Japan and Japan-occupied China. 15,000 Eastern European Jews were granted asylum in the Japanese quarter of Shanghai, and another 17,000 in Japanese occupied Manchuria. During WWII, the Japanese consul in Germany saved 6,000 Jews from the Holocaust by issuing them visas to Japan, despite protests from Nazi Germany.
  • The world's two oldest family-run businesses are Japanese: the hot spring hotel Nishiyama Onsen Keiunkan (founded in 711) in Hayakawa, Yamanashi prefecture, and Hōshi (founded in 781), a ryokan in Komatsu, Ishikawa. Until a few years ago the palm went to Kongō Gumi (founded in 578), a Buddhist temple building firm headquartered in Osaka that went bankrupt in 2006.

It moved into the Japanese toy industry in 1966, and started producing video games in 1977, where it achieved international fame. Despite its success in the high-tech industry and its global market, Nintendo grew and has retained its headquarters in traditional and timeless Kyoto. The name Nintendo itself (任天堂) could be just as well be mistaken for a Buddhist temple's name.
  • Restaurants in Tokyo were awarded twice more Michelin stars than those in Paris, making it the culinary capital of the world. Tokyoites can choose where to dine from over 200,000 restaurants - a world record.

Its most famous contributions to modern technology are the VHS tape (developed by JVC in 1976), the Compact Disk and the CD-ROM (both developed by Sony in collaboration with the Dutch company Philips). Sony also invented the now defunct Betamax videocassette and the Mini Disk (MD). Inventions falsely attributed to Japan include the Quartz Watch (invented by the Canadian Warren Marrison, but first commercialised by Seiko in 1969), the walkman (Sony, who claimed the invention in 1979, admitted in 2003 that German citizen Andreas Pavel came with the idea 2 years earlier), video games (an invention claimed by both Britain and the USA), mobile phones (invented by AT&T in 1947), or comic books (first published in Europe in the early 1800's).
  • The shinkansen was the world's first commercial bullet train, starting service on 1 October 1964, in time for the first Tokyo Olympics, initially at speeds of up to 210 km/h (130 mph). Nowadays Japan is still leading high-speed train technology with the L0 Series magnetic levitation (maglev) trains, which set a land speed record for rail vehicles of 603 km/h (375 mph) on 21 April 2015. The L0 shinkansen is due to operate from 2027.
