Country and population

Japan is an island nation in the Pacific Ocean, east of China and Korea. It has a surface area of 374,744 square kilometres (144,689 square miles), a coastline of 29,751 kilometres and a population of around 126.15 million (estimate 2019), with a population density of 334 inhabitants per square kilometre. Most of Japan is mountainous and unsuitable for urbanisation; this results in pockets with high population density. The highest point of Japan is Mount Fuji, or Fuji-san (富士山) in Japanese, an active volcano with a low risk of eruption, with 3,776 metres (12,388 feet).

More on the regions of Japan.


The name "Japan" (日本 Nihon or Nippon) originates from the Chinese language, and means "Origin of the Sun", or "Land of the Rising Sun", since to Chinese Japan was where the sun appeared. In the old times, China was considered the centre of the world (the name China 中国 / 中國, literally means "the central country"). The traditional name for Japan was Yamato , meaning "Place of mountains", but written as 大和 ("great harmony"). The Chinese word Ribenguo/Jihpenkuo 日本國 was Europeanised to Jipang. In the Chinese Wu language (modern Shanghainese), Japan is still pronounced as "Zeppen". The name "Japan" comes from the word "Cipangu", which Marco Polo brought from China in the 13th century. After the discovery by the Portuguese in 1542, Japan was known in Europe as "The Japans", denoting the whole archipelago.


The Japanese flag is called the "Hinomaru" (日の丸), meaning "the disc which is the sun", officially called Nisshōki (日章旗) and adopted as Japan's national flag in 1870. The red circle symbolises the rising sun after the name of the country. The flag with the sun off-centre and rays emanating from it is the Japanese Naval ensign. It is not, as commonly believed, the old national flag, nor is it the "war" flag.


The flag has a width/length ratio of 7:10. The sun, a circle centred on the flag, has a diameter of 3/5 the width. The sun is positioned 1/100th the length closer to the pole edge of the flag.


Japan's capital city is Tokyo (東京 Tōkyō), meaning "eastern capital". It was given this name during the Meiji Restoration, which started in 1868. It was previously known as Edo(江戸) or Yedo. Edo has been the capital of Japan since the beginning of the Tokugawa shogunate in 1600. Before this, Kyoto (京都), which means "capital city", was the capital, and before that Nara (奈良).

Tokyo raw facts:

  • Population: 9,214m (23 wards, 2015), 13,929,286 (Tokyo Metropolitan Area, October 2018)
  • Population density: 6,310/square kilometer
  • Tokyo Prefecture consists of 23 special wards ("Metropolitan Tokyo"), 26 cities, one district, & 4 subprefectures
  • The seat of the Japanese government & the Imperial Household
  • Part of the largest metropolitan area (Greater Tokyo Area) with 38.14 million inhabitants
  • Largest metropolitan with a GDP of US$869 billion (2015)
  • Hosts 47 of the Fortune Global 500 companies.
  • Started as a small fishing village.
  • Measures 90 kilometres in length (east to west) and 25 north to south.
  • Tokyo has some outlying islands, the farthest 1,850 kilometres from central Tokyo.

The archipelago:

Japan consists of four large islands and 6,852 smaller islands, 430 of which are inhabited. The four major islands are known as Hokkaido (北海道 Hokkaidō, also the largest prefecture) as the northernmost, Honshu (本州 Honshū, "main province") the main island, Shikoku (四国, "four provinces) the smallest of the four, and Kyushu (九州 Kyūshū , "Nine Provinces") the southernmost island of the four. The most famous of the smaller islands is Okinawa (沖縄) in the Ryukyu Islands and is the southernmost part of Japan.

The Emperor:

The current Emperor is His Imperial Highness Emperor Naruhito. He is married to Empress Masako. Emperor Naruhito is the son of Emperor Akihito. The Japanese emperor rules for a lifetime, after which the rule passes on to his son. Emperor Akihito abdicated on 30 April 2019 due to his age and declining health. Emperor Naruhito ascended to the throne on 1 May 2019, at which time a new era started: Reiwa (令和, intended to mean "beautiful harmony"). The Japanese Imperial House is the oldest continuing hereditary monarchy globally, dating back over 1,400 years. According to legend, they are direct descendants of the sun goddess Amaterasu Omikami, who, according to legend, created Japan with her brother Susano no Mikoto. The Emperor serves a ceremonial role only and is not involved in the national decision-making process.

What the Emperor does:

  • The Emperor is the symbol of the State and the unity of the people, deriving his position from the will of the people with whom resides sovereign power (the Constitution of Japan, Article 1).
  • The Imperial Throne is dynastic and succeeded to by the Imperial House Law passed by the Diet (Constitution, Article 2).
  • The Emperor performs only such acts in matters of state as are provided for in the Constitution and has no powers related to the government (Constitution, Article 4(1)).
  • The Emperor's acts in matters of State (Constitution, Articles 6, Article 7, and Article 4(2))
  • Appointment of the Prime Minister as designated by the Diet and the Chief Justice of the Supreme Court
  • The advice and approval of the Cabinet are required for all acts of the Emperor in matters of State, and the Cabinet is responsible for them (Constitution, Article 3).

  • Convocation of the Diet
  • Dissolution of the House of Representatives and proclamation of a general election of members of the Diet
  • Attestation of the appointment and dismissal of Ministers of State and other officials as provided for by law, and of full powers and credentials of Ambassadors and Ministers

Japan is a unitary parliamentary democracy and a constitutional monarchy. The current Prime Minister of Japan is a member of the Liberal Democratic Party (LDP), Shinzo Abe, who assumed office on 26 September 2012. Japan is divided into 47 administrative units known as prefectures (都道府県 todōfuken) There is one to (都): Tōkyō-tō (東京都); one do (道): Hokkaidō (北海道); two fu (府): Kyōto-fu (京都府) and Osaka-fu (大阪府); and 43 ken (県). Though the names may be different, all administrative units are the same.


The National Diet of Japan ((国会 Kokkai) consists of two chambers: the House of Representatives (衆議院 Shūgiin, Lower House) and the House of Councillors (参議院 Sangiin, Upper House). The 480 members of the Lower House are elected for a four-year term and are more powerful than the 242 councillors elected for a six-year term (121 members are subject to election every three years). The representatives are elected from 300 single-member constituencies (300 members in total) and 11 multi-member constituencies (180 members). Not only can the Lower House override votes of the Upper House with a two-thirds majority of members present, but it can also insist on its decisions in case of disagreement between the two chambers on the budget, treaties, or designation of the prime minister.

Times and dates:

Japan's time zone is Greenwich Mean Time plus 9 hours and has no daylight savings time. The Japanese use their calendar system in conjunction with the Gregorian Calendar. The Japanese calendar starts counting from year one at the start of the rule of a new Emperor, but its year's ends and beginnings coincide with the Gregorian Calendar. Each year is divided into the 12 Gregorian months, which are counted as Month 1 through Month 12. Weekdays are given the names of the primary natural elements, as defined by the Chinese: Moon (月曜日 getsuyōbi Monday), Fire (火曜日 kayōbi Tuesday), Water (水曜日 suiyōbi Wednesday), Wood (木曜日 mokuyōbi Thursday), Metal (金曜日 kin'yōbi Friday), Earth (土曜日 doyōbi Saturday), and Sun (日曜日 nichiyōbi Sunday).


The national language is Japanese. The writing system is derived from the Chinese language. The Chinese characters were supplemented with a simplified syllabary known as hiragana, often used as a writing system for female writers. Later another syllabary, known as katakana, was introduced. All three writing systems are still used in Japanese, along with a romanised version of the Japanese language, known as rōmaji.


The Japanese currency is the Yen (JPY – ¥ or 円). One hundred yen roughly equal 91 cents (USD 0.91), 64 pence (GBP 0.64) or 74 euro cent (EUR 0.74) in value (June 2021). The one-yen coin is said to be the only coin in the world that can float on water. In the year 2000, a 2000-yen banknote was introduced. However, it is rare since it has not been reprinted, and most electronic dispensers cannot process it.

Japan is situated in the temperate zone and has four distinct seasons. Due to its wide latitude, it has various climates: Hokkaido in the far north has a cool temperate climate, with moderate summers and cold winters. In contrast, Okinawa has a subtropic climate with hot and humid summers and moderate winters. Japan's climate is influenced by two ocean currents, the warm Black Current and the cold Okhotsk Current. Japan is a rainy country. From late June to the middle of July is Japan's rainy season or tsuyu (梅雨, "plum rain"). September and October are known as the typhoon (台風 tai-fū) season.

Natural phenomena:

Japan rests on a geologically active area. The islands were, in fact, created from two tectonic plates pushing against each other and emerging from the ocean. These tectonic plates are the cause of seismic and geologic activities.

There are 108 active volcanoes in Japan. The best known among these are Mount Fuji (about 100 kilometres southwest of Tokyo) and Mount Aso (阿蘇山 Aso-san) in Kyushu.

Earthquakes are an everyday occurrence, though most of them are hardly noticeable tremors. The two most recent massive earthquakes were the Great Hanshin Earthquake (阪神・淡路大震災 Hanshin Daishinsai) which occurred in Kobe on January 17, 1995. They had a magnitude of 6.9 on the Richter scale, claiming more than 5,500 lives. The most powerful earthquake ever to hit Japan, the Great East Japan Earthquake (東日本大震災 Higashi Nihon Daishinsai) on March 11, 2011, with a magnitude of 9.0 and the epicentre about 70 kilometres off the Tōhoku coast, triggering a tidal wave (津波 tsunami, "harbour wave") of up to 40 metres in height and claiming the lives of 15,842 people, with 3,485 still missing. The worst earthquake in world history on September 1, 1923, the Great Kanto Earthquake (関東大震災 Kantō Daishinsai) laid waste to Tokyo. The quake, with a magnitude of 8.3, and subsequent fires claimed 142,800 lives.

Every year, Asia is plagued by a large number of typhoons, and Japan is no exception. Typhoons are violent storms that develop over the southern Pacific Ocean. The word "typhoon" comes from the Chinese "taifeng". Typhoons occur in greater numbers during September and October.

It's not all bad, though; the geologic activities also produce many natural hot springs, which the Japanese have eagerly transformed into spa-like bathhouses. These bathhouses, known as onsen (温泉), can be found all over Japan.


The Japanese power net uses 100 Volt AC at 50Hz (in northeastern Japan) and 60Hz (in southwestern Japan). The plug has the same shape as US plugs, so electric appliances can safely be connected.

For European and Australian equipment, a power converter is required. Please note that an adapter plug will not convert the voltage between 220 Volts and 100 Volts. Using these plugs without a power converter might damage equipment. Correct settings are essential when using a two-way power converter, as mistakes could result in 484 Volts being served into a machine designed for only 100 Volts.


The video system is also similar to the US NTSC system. For European and Australian application, it is recommended to check whether it can play and record NTSC before buying videotapes in Japan, as these countries employ the PAL system. When purchasing video recorders in Japan, it should be noted that most cannot record or play PAL videos.DVDs are Region 2, as used in Europe. Region 2 DVDs will not play on Region 1 or 4 players used in the United States and Australia. A region free player may be the solution when importing DVDs from Japan. DVD players are usually capable of playing both PAL and NTSC discs.


There are two main religions in Japan, Shinto and Buddhism, and a small Christian community (about one per cent of the population). The constitution guarantees freedom to follow any religion, as the state is prohibited from religious education and supporting any religion. This was not always the case. With the Meiji Restoration of 1868, a "creation myth" for Japan which had been growing in importance over the past century was placed at the centre of the new constitution, enshrining the Emperor as a God and a direct descendant of Amaterasu, the sun goddess and setting Shinto as the State religion.

Until this time, Shinto and Buddhism had lived side by side, often with temples and shrines mixed up on the same sites. The Japanese tended to have a Shinto wedding and Buddhist funeral as most people practised both religions – something that continues today. The Meiji Restoration demanded that the two be separated, and many temples were forcibly moved to other sites, although a few remain in mixed locations.

Most people today claim to be Buddhist (about 90 million or 75% of the population). Buddhism originated in India, and the form in Japan was imported via China and Korea around the sixth century. With imperial support, it spread quickly. Buddhism preaches that by personal development (achieved in different ways according to each sect), the follower can develop a true understanding of the relative nature of the self and the universe and break free from the cycle of rebirth to live forever in nirvana – that is, achieve the state of enlightenment that is Buddhahood. Buddhism took many forms in Japan, the most famous of which is probably Zen, but most preach that all people can reach salvation, as with other forms of Mahayana Buddhism.

Shinto developed from local Japanese animistic beliefs. Shrines are built to local gods and goddesses, and ancestors are worshipped. Many of Japan's festivals are tied to Shinto beliefs, such as Obon, the most important date of the Japanese festivals calendar.

Christianity was introduced in 1549 by Saint Francis Xavier but was prohibited shortly after as the shogunate felt it was a divisive influence that could upset the status quo. Persecutions followed, and many followers were tortured and put to death.

Confucianism has also influenced Japanese thought more as an ethical or moral tradition than as a religious system. Introduced at about the same time as Buddhism and writing to Japan, the Japanese incorporated elements in their moral system in, as ever, a generally eclectic sense.
