Japan ⁱ/dʒəˈpæn/ (Japanese: 日本 Nihon or Nippon; formally 日本国  Nippon-koku or Nihon-koku, literally the State of Japan) is an island nation in East Asia. Located in the Pacific Ocean, it lies to the east of the Sea of Japan, China, North Korea, South Korea and Russia, stretching from the Sea of Okhotsk in the north to the East China Sea and Taiwan in the south. The characters that make up Japan's name mean "sun-origin", which is why Japan is sometimes referred to as the "Land of the Rising Sun".

Japan is an archipelago of 6,852 islands. The four largest islands are Honshū, Hokkaidō, Kyūshū and Shikoku, together accounting for ninety-seven percent of Japan's land area. Japan has the world's tenth-largest population, with over 127 million people. The Greater Tokyo Area, which includes the de facto capital city of Tokyo and several surrounding prefectures, is the largest metropolitan area in the world, with over 30 million residents.

Archaeological research indicates that people lived in Japan as early as the Upper Paleolithic period. The first written mention of Japan is in Chinese history texts from the 1st century AD. Influence from other nations followed by long periods of isolation has characterized Japan's history. In the late 19th and early 20th centuries, victory in the First Sino-Japanese War, the Russo-Japanese War and World War I allowed Japan to expand its empire during a period of increasing militarism. The Second Sino-Japanese War of 1937 expanded into part of World War II in 1941, which came to an end in 1945 following the atomic bombings of Hiroshima and Nagasaki. Since adopting its revised constitution in 1947, Japan has maintained a unitary constitutional monarchy with an emperor and an elected parliament called the Diet.

A major economic power,^[2] Japan has the world's third-largest economy by nominal GDP and fourth-largest economy by purchasing power parity. It is also the world's fourth-largest exporter and fourth-largest importer. Although Japan has officially renounced its right to declare war, it maintains a modern military force in self-defense and peacekeeping roles. After Singapore, Japan has the lowest homicide rate (including attempted homicide) in the world.^[10] According to both UN and WHO estimates, Japan has the longest life expectancy of any country in the world. According to the UN, it has the third lowest infant mortality rate.^[11][12]

Etymology[link]

The English word Japan is an exonym. The Japanese names for Japan are Nippon (にっぽん^?)  listen (help·info) and Nihon (にほん^?)  listen (help·info); both names are written using the kanji 日本. The Japanese name Nippon is used for most official purposes, including on Japanese yen, postage stamps, and for many international sporting events. Nihon is a more casual term and is used in contemporary speech.

Japanese people refer to themselves as Nihonjin (日本人^?) and to their language as Nihongo (日本語^?). Both Nippon and Nihon mean "sun-origin" and are often translated as Land of the Rising Sun. This nomenclature comes from Japanese missions to Imperial China and refers to Japan's eastward position relative to China. Before Nihon came into official use, Japan was known as Wa (倭^?) or Wakoku (倭国^?).^[13]

The English word for Japan came to the West via early trade routes. The early Mandarin or possibly Wu Chinese (吳語) word for Japan was recorded by Marco Polo as Cipangu. In modern Shanghainese, a Wu dialect, the pronunciation of characters 日本 'Japan' is Zeppen [zəʔpən]. The old Malay word for Japan, Jepang, was borrowed from a Chinese language – Jih'pen'kuo^[14]—, and this Malay word was encountered by Portuguese traders in Malacca in the 16th century. Portuguese traders were the first to bring the word to Europe.^[15] It was first recorded in English in a 1565 letter, spelled Giapan.^[16]

History[link]

Prehistory and ancient history[link]

The Golden Hall and five-storey pagoda of Hōryū-ji, among the oldest wooden buildings in the world, National Treasures, and a UNESCO World Heritage Site

A Paleolithic culture around 30,000 BC constitutes the first known habitation of the Japanese archipelago. This was followed from around 14,000 BC (the start of the Jōmon period) by a Mesolithic to Neolithic semi-sedentary hunter-gatherer culture, who include ancestors of both the contemporary Ainu people and Yamato people,^[17][18] characterized by pit dwelling and rudimentary agriculture.^[19] Decorated clay vessels from this period are some of the oldest surviving examples of pottery in the world. Around 300 BC, the Yayoi people began to enter the Japanese islands, intermingling with the Jōmon.^[20] The Yayoi period, starting around 500 BC, saw the introduction of practices like wet-rice farming,^[21] a new style of pottery,^[22] and metallurgy, introduced from China and Korea.^[23]

Japan first appears in written history in the Chinese Book of Han.^[24] According to the Records of the Three Kingdoms, the most powerful kingdom on the archipelago during the 3rd century was called Yamataikoku. Buddhism was first introduced to Japan from Baekje of Korea, but the subsequent development of Japanese Buddhism was primarily influenced by China.^[25] Despite early resistance, Buddhism was promoted by the ruling class and gained widespread acceptance beginning in the Asuka period (592–710).^[26]

The Nara period (710–784) of the 8th century marked the emergence of a strong Japanese state, centered on an imperial court in Heijō-kyō (modern Nara). The Nara period is characterized by the appearance of a nascent literature as well as the development of Buddhist-inspired art and architecture.^[27] The smallpox epidemic of 735–737 is believed to have killed as much as one-third of Japan's population.^[28] In 784, Emperor Kammu moved the capital from Nara to Nagaoka-kyō before relocating it to Heian-kyō (modern Kyoto) in 794.

Byōdō-in (1053) is a temple of Pure Land Buddhism. It was registered to the UNESCO World Heritage Site.

This marked the beginning of the Heian period (794–1185), during which a distinctly indigenous Japanese culture emerged, noted for its art, poetry and prose. Lady Murasaki's The Tale of Genji and the lyrics of Japan's national anthem Kimigayo were written during this time.^[29]

Buddhism began to spread during the Heian era chiefly through two major sects, Tendai by Saichō, and Shingon by Kūkai. Pure Land Buddhism greatly becomes popular in the latter half of the 11th century.

Feudal era[link]

Japan's feudal era was characterized by the emergence and dominance of a ruling class of warriors, the samurai. In 1185, following the defeat of the Taira clan, sung in the epic Tale of Heike, samurai Minamoto no Yoritomo was appointed shogun and established a base of power in Kamakura. After his death, the Hōjō clan came to power as regents for the shoguns. The Zen school of Buddhism was introduced from China in the Kamakura period (1185–1333) and became popular among the samurai class.^[30] The Kamakura shogunate repelled Mongol invasions in 1274 and 1281, but was eventually overthrown by Emperor Go-Daigo. Go-Daigo was himself defeated by Ashikaga Takauji in 1336.

Ginkaku-ji in Kyoto (Higashiyama period in Muromachi Period, c. 1489). It was registered as part of the UNESCO World Heritage Site "Historic Monuments of Ancient Kyoto".

Ashikaga Takauji establishes the shogunate in Muromachi, Kyoto. It is a start of Muromachi Period (1336–1573). The Ashikaga shogunate receives glory in the age of Ashikaga Yoshimitsu, and the culture based on Zen Buddhism (art of Miyabi) has prospered. It evolves to Higashiyama Culture, and has prospered until the 16th century. On the other hand, the succeeding Ashikaga shogunate failed to control the feudal warlords (daimyo), and a civil war (the Ōnin War) began in 1467, opening the century-long Sengoku period ("Warring States").^[31]

During the 16th century, traders and Jesuit missionaries from Portugal reached Japan for the first time, initiating direct commercial and cultural exchange between Japan and the West. Oda Nobunaga conquered many other daimyo using European technology and firearms; after he was assassinated in 1582, his successor Toyotomi Hideyoshi unified the nation in 1590. Hideyoshi invaded Korea twice, but following defeats by Korean and Ming Chinese forces and Hideyoshi's death, Japanese troops were withdrawn in 1598.^[32] This age is called Azuchi-Momoyama Period (1573–1603).

Tokugawa Ieyasu served as regent for Hideyoshi's son and used his position to gain political and military support. When open war broke out, he defeated rival clans in the Battle of Sekigahara in 1600. Ieyasu was appointed shogun in 1603 and established the Tokugawa shogunate at Edo (modern Tokyo).^[33] The Tokugawa shogunate enacted measures including buke shohatto, as a code of conduct to control the autonomous daimyo;^[34] and in 1639, the isolationist sakoku ("closed country") policy that spanned the two and a half centuries of tenuous political unity known as the Edo period (1603–1868).^[35] The study of Western sciences, known as rangaku, continued through contact with the Dutch enclave at Dejima in Nagasaki. The Edo period also gave rise to kokugaku ("national studies"), the study of Japan by the Japanese.^[36]

Modern era[link]

On 31 March 1854, Commodore Matthew Perry and the "Black Ships" of the United States Navy forced the opening of Japan to the outside world with the Convention of Kanagawa. Subsequent similar treaties with Western countries in the Bakumatsu period brought economic and political crises. The resignation of the shogun led to the Boshin War and the establishment of a centralized state nominally unified under the Emperor (the Meiji Restoration).^[37]

Adopting Western political, judicial and military institutions, the Cabinet organized the Privy Council, introduced the Meiji Constitution, and assembled the Imperial Diet. The Meiji Restoration transformed the Empire of Japan into an industrialized world power that pursued military conflict to expand its sphere of influence. After victories in the First Sino-Japanese War (1894–1895) and the Russo-Japanese War (1904–1905), Japan gained control of Taiwan, Korea, and the southern half of Sakhalin.^[38] Japan's population grew from 35 million in 1873 to 70 million in 1935.^[39]

The Meiji Emperor (1868–1912), in whose name imperial rule was restored at the end of the Tokugawa shogunate

The early 20th century saw a brief period of "Taishō democracy" overshadowed by increasing expansionism and militarization. World War I enabled Japan, on the side of the victorious Allies, to widen its influence and territorial holdings. It continued its expansionist policy by occupying Manchuria in 1931; as a result of international condemnation of this occupation, Japan resigned from the League of Nations two years later. In 1936, Japan signed the Anti-Comintern Pact with Nazi Germany, and the 1940 Tripartite Pact made it one of the Axis Powers.^[40] In 1941, Japan negotiated the Soviet–Japanese Neutrality Pact.^[41]

The Empire of Japan invaded other parts of China in 1937, precipitating the Second Sino-Japanese War (1937–1945). In 1940, the Empire then invaded French Indochina, after which the United States placed an oil embargo on Japan.^[42] On December 7, 1941, Japan attacked the US naval base at Pearl Harbor and declared war, bringing the US into World War II.^[43][44] After the Soviet invasion of Manchuria and the atomic bombings of Hiroshima and Nagasaki in 1945, Japan agreed to an unconditional surrender on 15 August.^[45] The war cost Japan and the rest of the Greater East Asia Co-Prosperity Sphere millions of lives and left much of the nation's industry and infrastructure destroyed. The Allies (led by the US) repatriated millions of ethnic Japanese from colonies and military camps throughout Asia, largely eliminating the Japanese empire and restoring the independence of its conquered territories.^[46] The Allies also convened the International Military Tribunal for the Far East on May 3, 1946 to prosecute some Japanese leaders for war crimes. However, the bacteriological research units and members of the imperial family involved in the war were exonerated from criminal prosecutions by the Supreme Allied Commander despite calls for trials for both groups.^[47]

In 1947, Japan adopted a new constitution emphasizing liberal democratic practices. The Allied occupation ended with the Treaty of San Francisco in 1952^[48] and Japan was granted membership in the United Nations in 1956. Japan later achieved rapid growth to become the second-largest economy in the world, until surpassed by China in 2010. This ended in the mid-1990s when Japan suffered a major recession. In the beginning of the 21st century, positive growth has signaled a gradual economic recovery.^[49] On 11 March 2011, Japan suffered the strongest earthquake in its recorded history; this triggered the Fukushima Daiichi nuclear disaster, one of the worst disasters in the history of nuclear power.^[50]

Politics[link]

Emperor Akihito and Empress Michiko

Japan is a constitutional monarchy where the power of the Emperor is very limited. As a ceremonial figurehead, he is defined by the constitution as "the symbol of the state and of the unity of the people". Power is held chiefly by the Prime Minister of Japan and other elected members of the Diet, while sovereignty is vested in the Japanese people.^[51] Akihito is the current Emperor of Japan; Naruhito, Crown Prince of Japan, stands as next in line to the throne.

Japan's legislative organ is the National Diet, a bicameral parliament. The Diet consists of a House of Representatives with 480 seats, elected by popular vote every four years or when dissolved, and a House of Councillors of 242 seats, whose popularly elected members serve six-year terms. There is universal suffrage for adults over 20 years of age,^[2] with a secret ballot for all elected offices.^[51] In 2009, the social liberal Democratic Party of Japan took power after 54 years of the liberal conservative Liberal Democratic Party's rule.^[52]

The Prime Minister of Japan is the head of government and is appointed by the Emperor after being designated by the Diet from among its members. The Prime Minister is the head of the Cabinet and appoints and dismisses the Ministers of State. Naoto Kan was designated by the Diet to replace Yukio Hatoyama as the Prime Minister of Japan on June 2, 2010.^[53] Although the Prime Minister is formally appointed by the Emperor, the Constitution of Japan explicitly requires the Emperor to appoint whoever is designated by the Diet. Emperor Akihito formally appointed Kan as the country's 94th Prime Minister on 8 June.^[54]

Historically influenced by Chinese law, the Japanese legal system developed independently during the Edo period through texts such as Kujikata Osadamegaki.^[55] However, since the late 19th century the judicial system has been largely based on the civil law of Europe, notably Germany. For example, in 1896, the Japanese government established a civil code based on a draft of the German Bürgerliches Gesetzbuch; with post–World War II modifications, the code remains in effect.^[56] Statutory law originates in Japan's legislature and has the rubber stamp of the Emperor. The Constitution requires that the Emperor promulgate legislation passed by the Diet, without specifically giving him the power to oppose legislation.^[51] Japan's court system is divided into four basic tiers: the Supreme Court and three levels of lower courts.^[57] The main body of Japanese statutory law is called the Six Codes.^[58]

Foreign relations and military[link]

Japan is a member of the G8, APEC, and "ASEAN Plus Three", and is a participant in the East Asia Summit. Japan signed a security pact with Australia in March 2007^[59] and with India in October 2008.^[60] It is the world's third largest donor of official development assistance after the United States and France, donating US$9.48 billion in 2009.^[61]

Japan has close economic and military relations with the United States; the US-Japan security alliance acts as the cornerstone of the nation's foreign policy.^[62] A member state of the United Nations since 1956, Japan has served as a non-permanent Security Council member for a total of 19 years, most recently for 2009 and 2010. It is one of the G4 nations seeking permanent membership in the Security Council.^[63]

Japan is engaged in several territorial disputes with its neighbors: with Russia over the South Kuril Islands, with South Korea over the Liancourt Rocks, with China and Taiwan over the Senkaku Islands, and with China over the EEZ around Okinotorishima.^[64] Japan also faces an ongoing dispute with North Korea over the latter's abduction of Japanese citizens and its nuclear weapons and missile program (see also Six-party talks).^[65]

Japan maintains one of the largest military budgets of any country in the world.^[66] Japan contributed non-combatant troops to the Iraq War but subsequently withdrew its forces.^[67] The Japan Maritime Self-Defense Force is a regular participant in RIMPAC maritime exercises.^[68]

Japan's military is restricted by Article 9 of the Japanese Constitution, which renounces Japan's right to declare war or use military force in international disputes. Japan's military is governed by the Ministry of Defense, and primarily consists of the Japan Ground Self-Defense Force (JGSDF), the Japan Maritime Self-Defense Force (JMSDF) and the Japan Air Self-Defense Force (JASDF). The forces have been recently used in peacekeeping operations; the deployment of troops to Iraq marked the first overseas use of Japan's military since World War II.^[67] Nippon Keidanren has called on the government to lift the ban on arms exports so that Japan can join multinational projects such as the Joint Strike Fighter.^[69]

Administrative divisions[link]

Japan consists of forty-seven prefectures, each overseen by an elected governor, legislature and administrative bureaucracy. Each prefecture is further divided into cities, towns and villages.^[70] The nation is currently undergoing administrative reorganization by merging many of the cities, towns and villages with each other. This process will reduce the number of sub-prefecture administrative regions and is expected to cut administrative costs.^[71]

Geography[link]

Japan has a total of 6,852 islands extending along the Pacific coast of East Asia.^[72][73] The country, including all of the islands it controls, lies between latitudes 24° and 46°N, and longitudes 122° and 146°E. The main islands, from north to south, are Hokkaidō, Honshū, Shikoku and Kyūshū. The Ryūkyū Islands, including Okinawa, are a chain to the south of Kyūshū. Together they are often known as the Japanese Archipelago.^[74]

About 73 percent of Japan is forested, mountainous, and unsuitable for agricultural, industrial, or residential use.^[2][75] As a result, the habitable zones, mainly located in coastal areas, have extremely high population densities. Japan is one of the most densely populated countries in the world.^[76]

The islands of Japan are located in a volcanic zone on the Pacific Ring of Fire. They are primarily the result of large oceanic movements occurring over hundreds of millions of years from the mid-Silurian to the Pleistocene as a result of the subduction of the Philippine Sea Plate beneath the continental Amurian Plate and Okinawa Plate to the south, and subduction of the Pacific Plate under the Okhotsk Plate to the north. Japan was originally attached to the eastern coast of the Eurasian continent. The subducting plates pulled Japan eastward, opening the Sea of Japan around 15 million years ago.^[77]

Japan has 108 active volcanoes. Destructive earthquakes, often resulting in tsunami, occur several times each century.^[78] The 1923 Tokyo earthquake killed over 140,000 people.^[79] More recent major quakes are the 1995 Great Hanshin earthquake and the 2011 Tōhoku earthquake, a 9.0-magnitude^[80] quake which hit Japan on 11 March 2011, and triggered a large tsunami.^[50] On 24 May 2012, 6.1 magnitude earthquake struck off the coast of northearstern Japan.No tsunami is expected though.^[81]

Climate[link]

The climate of Japan is predominantly temperate, but varies greatly from north to south. Japan's geographical features divide it into six principal climatic zones: Hokkaidō, Sea of Japan, Central Highland, Seto Inland Sea, Pacific Ocean, and Ryūkyū Islands. The northernmost zone, Hokkaido, has a humid continental climate with long, cold winters and very warm to cool summers. Precipitation is not heavy, but the islands usually develop deep snowbanks in the winter.^[82]

In the Sea of Japan zone on Honshū's west coast, northwest winter winds bring heavy snowfall. In the summer, the region is cooler than the Pacific area, though it sometimes experiences extremely hot temperatures because of the foehn wind. The Central Highland has a typical inland humid continental climate, with large temperature differences between summer and winter, and between day and night; precipitation is light, though winters are usually snowy. The mountains of the Chūgoku and Shikoku regions shelter the Seto Inland Sea from seasonal winds, bringing mild weather year-round.^[83]

The Pacific coast features a humid subtropical climate that experiences milder winters with occasional snowfall and hot, humid summers because of the southeast seasonal wind. The Ryukyu Islands have a subtropical climate, with warm winters and hot summers. Precipitation is very heavy, especially during the rainy season. The generally humid, temperate climate exhibits marked seasonal variation such as the blooming of the spring cherry blossoms, the calls of the summer cicada and fall foliage colors that are celebrated in art and literature.^[84]

The average winter temperature in Japan is 5.1 °C (41.2 °F) and the average summer temperature is 25.2 °C (77.4 °F).^[85] The highest temperature ever measured in Japan—40.9 °C (105.6 °F)—was recorded on 16 August 2007.^[86] The main rainy season begins in early May in Okinawa, and the rain front gradually moves north until reaching Hokkaidō in late July. In most of Honshū, the rainy season begins before the middle of June and lasts about six weeks. In late summer and early autumn, typhoons often bring heavy rain.^[87]

Biodiversity[link]

Japan has nine forest ecoregions which reflect the climate and geography of the islands. They range from subtropical moist broadleaf forests in the Ryūkyū and Bonin Islands, to temperate broadleaf and mixed forests in the mild climate regions of the main islands, to temperate coniferous forests in the cold, winter portions of the northern islands.^[88] Japan has over 90,000 species of wildlife, including the brown bear, the Japanese macaque, the Japanese raccoon dog, and the Japanese giant salamander.^[89] A large network of national parks has been established to protect important areas of flora and fauna as well as thirty-seven Ramsar wetland sites.^[90][91]

Environment[link]

In the period of rapid economic growth after World War II, environmental policies were downplayed by the government and industrial corporations; as a result, environmental pollution was widespread in the 1950s and 1960s. Responding to rising concern about the problem, the government introduced several environmental protection laws in 1970.^[92] The oil crisis in 1973 also encouraged the efficient use of energy due to Japan's lack of natural resources.^[93] Current environmental issues include urban air pollution (NOx, suspended particulate matter, and toxics), waste management, water eutrophication, nature conservation, climate change, chemical management and international co-operation for conservation.^[94]

Japan is one of the world's leaders in the development of new environment-friendly technologies, and is ranked 20th best in the world in the 2010 Environmental Performance Index.^[95] As a signatory of the Kyoto Protocol, and host of the 1997 conference which created it, Japan is under treaty obligation to reduce its carbon dioxide emissions and to take other steps to curb climate change.^[96]

Economy[link]

The Tokyo Stock Exchange, the largest stock exchange in Asia.^[97]

Some of the structural features for Japan's economic growth developed in the Edo period, such as the network of transport routes, by road and water, and the futures contracts, banking and insurance of the Osaka rice brokers.^[98] During the Meiji period from 1868, Japan expanded economically with the embrace of the market economy.^[99] Many of today's enterprises were founded at the time, and Japan emerged as the most developed nation in Asia.^[100] The period of overall real economic growth from the 1960s to the 1980s has been called the Japanese post-war economic miracle: it averaged 7.5 percent in the 1960s and 1970s, and 3.2 percent in the 1980s and early 1990s.^[101]

Growth slowed markedly in the 1990s during what the Japanese call the Lost Decade, largely because of the after-effects of the Japanese asset price bubble and domestic policies intended to wring speculative excesses from the stock and real estate markets. Government efforts to revive economic growth met with little success and were further hampered by the global slowdown in 2000.^[2] The economy showed strong signs of recovery after 2005; GDP growth for that year was 2.8 percent, surpassing the growth rates of the US and European Union during the same period.^[102]

As of 2011^[update], Japan is the third largest national economy in the world, after the United States and China, in terms of nominal GDP,^[103] and the fourth largest national economy in the world, after the United States, China and India in terms of purchasing power parity.^[7] As of January 2011^[update], Japan's public debt was more than 200 percent of its annual gross domestic product, the largest of any nation in the world. In August 2011, Moody's rating has cut Japan's long-term sovereign debt rating one notch from Aa3 to Aa2 inline with the size of the country's deficit and borrowing level. The large budget deficits and government debt since the 2009 global recession and followed by earthquake and tsunami in March 2011 made the rating downgrade.^[104] The service sector accounts for three quarters of the gross domestic product.^[105]

Japan has a large industrial capacity, and is home to some of the largest and most technologically advanced producers of motor vehicles, electronics, machine tools, steel and nonferrous metals, ships, chemical substances, textiles, and processed foods. Agricultural businesses in Japan cultivate 13 percent of Japan's land, and Japan accounts for nearly 15 percent of the global fish catch, second only to China.^[2] As of 2010, Japan's labor force consisted of some 65.9 million workers.^[106] Japan has a low unemployment rate of around four percent. Almost one in six Japanese, or 20 million people, lived in poverty in 2007.^[107] Housing in Japan is characterized by limited land supply in urban areas.^[108]
