Japan In Story
Japan (Japanese: 日本 Nippon [ɲip̚poɴ] or Nihon [ɲihoɴ]; formally 日本国 Nippon-koku or Nihon-koku, meaning “State of Japan”) is a sovereign island nation in East Asia. Located in the Pacific Ocean, it lies off the eastern coast of the Asian mainland, and stretches from the Sea of Okhotsk in the north to the East China Sea and Taiwan in the southwest.
The kanji that make up Japan’s name mean “sun origin”. 日 can be read as ni and means sun, while 本 can be read as hon, or pon and means origin. Japan is often referred to by the famous epithet “Land of the Rising Sun” in reference to its Japanese name.
Japan is a stratovolcanic archipelago consisting of about 6,852 islands. The four largest are Honshu, Hokkaido, Kyushu and Shikoku, which make up about ninety-seven percent of Japan’s land area and often are referred to as home islands. The country is divided into 47 prefectures in eight regions; Hokkaido being the northernmost prefecture and Okinawa being the southernmost one. The population of 127 million is the world’s tenth largest. Japanese people make up 98.5% of Japan’s total population. Approximately 9.1 million people live in the city of Tokyo, the capital of Japan.
Archaeological research indicates that Japan was inhabited 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 regions, mainly China, followed by periods of isolation, particularly from Western Europe, has characterized Japan’s history. From the 12th century until 1868, Japan was ruled by successive feudal military shoguns who ruled in the name of the Emperor.
Japan entered into a long period of isolation in the early 17th century, which was ended in 1853 when a United States fleet pressured Japan to open to the West. After nearly two decades of internal conflict and insurrection, the Imperial Court regained its political power in 1868 through the help of several clans from Chōshū and Satsuma, and the Empire of Japan was established. In the late 19th and early 20th centuries, victories 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 and the Japanese surrender. Since adopting its revised constitution on May 3, 1947 during the occupation by the SCAP, Japan has maintained a unitary parliamentary constitutional monarchy with an Emperor and an elected legislature called the National Diet.
Japan is a member of the UN, the OECD, the G7, the G8, and the G20 and is considered a great power. The country has the world’s third-largest economy by nominal GDP and the world’s fourth-largest economy by purchasing power parity. It is also the world’s fourth-largest exporter and fourth-largest importer. The country benefits from a highly skilled workforce and is among the most highly educated countries in the world, with one of the highest percentages of its citizens holding a tertiary education degree.
Although Japan has officially renounced its right to declare war, it maintains a modern military with the world’s eighth-largest military budget, used for self-defense and peacekeeping roles. Japan is a developed country with a very high standard of living and Human Development Index. Its population enjoys the highest life expectancy and the third lowest infant mortality rate in the world.
The Japanese word for Japan is 日本, which is pronounced Nihon or Nippon, and literally means “the origin of the sun”. The character nichi (日) means “sun” or “day”; hon (本) means “base” or “origin”. The compound therefore means “origin of the sun”, and is the source of the popular Western epithet “Land of the Rising Sun”.
The earliest record of the name “Nihon” appears in the Chinese historical records of the Tang dynasty, the Old Book of Tang. At the end of the seventh century, a delegation from Japan requested that Nihon be used as the name of their country. This name may have its origin in a letter sent in 607 and recorded in the official history of the Sui dynasty. Prince Shōtoku, the Regent of Japan, sent a mission to China with a letter in which he called himself ‘the Emperor of the Land where the Sun rises’ (日出處天子). The message said: “Here I the emperor of the country where the sun rises send a letter to the emperor of the country where the sun sets. How are you.” Prior to the adoption of Nihon, other terms such as “Yamato” (大和?, or Great Wa) and “Wakoku” (倭国?) were used. The term Wa (和?) is a homophone of Wo 倭 (pronounced Wa by the Japanese) used by the Chinese as a designation for the Japanese as early as the third century Three Kingdoms period. However, the Japanese dislike the connotation of Wa 倭 with the word ‘dwarf’ and it was therefore replaced with the Wa (和?), meaning “harmony”.
The English word Japan possibly derives from the historical Chinese pronunciation of 日本. The Old Mandarin or possibly early Wu Chinese pronunciation of 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, Japun or Japang, was borrowed from a southern coastal Chinese dialect, probably Fukienese or Ningpo, and this Malay word was encountered by Portuguese traders in South East Asia in the 16th century. These Early Portuguese traders then brought the word to Europe. The first record of this name in English is in a book published in 1577 and spelled Giapan, in a translation of a 1565 letter written by a Portuguese Jesuit Luís Fróis.
From the Meiji Restoration until the end of World War II, the full title of Japan was Dai Nippon Teikoku (大日本帝國), meaning “the Empire of Great Japan“. Today, the name Nihon-koku / Nippon-koku (日本国) is used as a formal modern-day equivalent with the meaning of “the State of Japan”; countries like Japan whose long form does not contain a descriptive designation are generally given a name appended by the character koku (国), meaning “country”, “nation” or “state”
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, characterized by pit dwelling and rudimentary agriculture. 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. The Yayoi period, starting around 500 BC, saw the introduction of practices like wet-rice farming, a new style of pottery, and metallurgy, introduced from China and Korea.
Japan first appears in written history in the Chinese Book of Han. 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, Korea and was promoted by Prince Shōtoku, but the subsequent development of Japanese Buddhism was primarily influenced by China. Despite early resistance, Buddhism was promoted by the ruling class and gained widespread acceptance beginning in the Asuka period (592–710).
The Nara period (710–784) of the 8th century marked an emergence of the centralized Japanese state centered on the 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. The smallpox epidemic of 735–737 is believed to have killed as much as one-third of Japan’s population. In 784, Emperor Kanmu moved the capital from Nara to Nagaoka-kyō before relocating it to Heian-kyō (modern Kyoto) in 794.
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. Murasaki Shikibu‘s The Tale of Genji and the lyrics of Japan’s national anthem “Kimigayo” were written during this time.
Buddhism began to spread during the Heian era chiefly through two major sects, Tendai by Saichō, and Shingon by Kūkai. Pure Land Buddhism (Jōdo-shū, Jōdo Shinshū) became greatly popular in the latter half of the 11th century.
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 in the Genpei War, sung in the epic Tale of Heike, samurai Minamoto no Yoritomo was appointed shogun by Emperor Go-Toba, and he 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. The Kamakura shogunate repelled Mongol invasions in 1274 and 1281, but was eventually overthrown by Emperor Go-Daigo. Emperor Go-Daigo was himself defeated by Ashikaga Takauji in 1336.
Ashikaga Takauji established the shogunate in Muromachi, Kyoto. This was the start of the Muromachi period (1336–1573). The Ashikaga shogunate achieved glory in the age of Ashikaga Yoshimitsu, and the culture based on Zen Buddhism (art of Miyabi) prospered. This evolved to Higashiyama Culture, and prospered until the 16th century. On the other hand, the succeeding Ashikaga shogunate failed to control the feudal warlords (daimyōs), and a civil war (the Ōnin War) began in 1467, opening the century-long Sengoku period (“Warring States”).
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. This allowed Oda Nobunaga to obtain European technology and firearms, which he used to conquer many other daimyōs. His consolidation of power began what was known as the Azuchi–Momoyama period (1573–1603). After he was assassinated in 1582, his successor Toyotomi Hideyoshi unified the nation in 1590 and launched two unsuccessful invasions of Korea in 1592 and 1597.
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. Tokugawa Ieyasu was appointed shogun by Emperor Go-Yōzei in 1603, and he established the Tokugawa shogunate in Edo (modern Tokyo). The Tokugawa shogunate enacted measures including buke shohatto, as a code of conduct to control the autonomous daimyōs; 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). 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.
On March 31, 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).
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. Japan’s population grew from 35 million in 1873 to 70 million in 1935.
World War I enabled Japan, on the side of the victorious Allies, to widen its influence and territorial holdings in Asia. The early 20th century saw a brief period of “Taishō democracy (1912–1926)” but the 1920s saw a fragile democracy buckle under a political shift towards fascism, the passing of laws against political dissent and a series of attempted coups. The subsequent “Shōwa period” initially saw the power of the military increased and brought about Japanese expansionism and militarization along with the totalitarianism and ultranationalism that are a part of fascist ideology. In 1931 Japan invaded and occupied Manchuria and following international condemnation of this occupation, Japan resigned from the League of Nations in 1933. In 1936, Japan signed the Anti-Comintern Pact with Germany, and the 1940 Tripartite Pact made it one of the Axis Powers. In 1941, following its defeat in the brief Soviet–Japanese Border War, Japan negotiated the Soviet–Japanese Neutrality Pact, which lasted until 1945 with the Soviet invasion of Manchuria.
The Empire of Japan invaded other parts of China in 1937, precipitating the Second Sino-Japanese War (1937–1945). The Imperial Japanese Army swiftly captured the capital Nanjing and conducted the Nanking Massacre. In 1940, the Empire then invaded French Indochina, after which the United States placed an oil embargo on Japan. On December 7–8, 1941, Japanese forces carried out surprise attacks on Pearl Harbor, British forces in Malaya, Singapore, and Hong Kong and declared war on the United States and the British Empire, bringing the US and the UK into World War II in the Pacific. After Allied victories across the Pacific during the next four years, which culminated in the Soviet invasion of Manchuria and the atomic bombings of Hiroshima and Nagasaki in 1945, Japan agreed to an unconditional surrender on August 15. The war cost Japan, its colonies, China and the war’s other combatants tens of millions of lives and left much of Japan’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. 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 Commander for the Allied Powers despite calls for the trial of both groups.
In 1947, Japan adopted a new constitution emphasizing liberal democratic practices. The Allied occupation ended with the Treaty of San Francisco in 1952 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. On March 11, 2011, Japan suffered one of the largest earthquakes in its recorded history; this triggered the Fukushima Daiichi nuclear disaster, one of the worst disasters in the history of nuclear power.
Japan has a total of 6,852 islands extending along the Pacific coast of East Asia. 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 Hokkaido, Honshu, Shikoku and Kyushu. The Ryukyu Islands, which include Okinawa, are a chain to the south of Kyushu. Together they are often known as the Japanese archipelago.
About 73 percent of Japan is forested, mountainous, and unsuitable for agricultural, industrial, or residential use. 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.
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. The Boso Triple Junction off the coast of Japan is a triple junction where the North American Plate, the Pacific Plate and the Philippine Sea Plate meets. 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.
Japan has 108 active volcanoes. During the twentieth century several new volcanoes emerged, including Shōwa-shinzan on Hokkaido and Myōjin-shō off the Bayonnaise Rocks in the Pacific. Destructive earthquakes, often resulting in tsunami, occur several times each century. The 1923 Tokyo earthquake killed over 140,000 people. More recent major quakes are the 1995 Great Hanshin earthquake and the 2011 Tōhoku earthquake, a 9.0-magnitude quake which hit Japan on March 11, 2011, and triggered a large tsunami. Japan is substantially prone to earthquakes, tsunami and volcanoes due to its location along the Pacific Ring of Fire. It has the 15th highest natural disaster risk as measured in the 2013 World Risk Index.
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: Hokkaido, Sea of Japan, Central Highland, Seto Inland Sea, Pacific Ocean, and Ryukyu 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.
In the Sea of Japan zone on Honshu’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. The Central Highland has a typical inland humid continental climate, with large temperature differences between summer and winter seasons, as well as large diurnal variation; 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.
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 average winter temperature in Japan is 5.1 °C (41.2 °F) and the average summer temperature is 25.2 °C (77.4 °F). The highest temperature ever measured in Japan 40.9 °C (105.6 °F) was recorded on August 16, 2007. The main rainy season begins in early May in Okinawa, and the rain front gradually moves north until reaching Hokkaido in late July. In most of Honshu, 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.
Japan is a constitutional monarchy whereby the power of the Emperor is very limited. As a ceremonial figurehead, he is defined by the constitution to be “the symbol of the State and of the unity of the people.” Power is held chiefly by the Prime Minister and other elected members of the Diet, while sovereignty is vested in the Japanese people. Akihito is the current Emperor of Japan; Naruhito, Crown Prince of Japan, stands as next in line to the Chrysanthemum Throne.
Japan’s legislative organ is the National Diet, seated in Chiyoda, Tokyo. The Diet is a bicameral body, consisting of a lower house, the House of Representatives with 475 seats, elected by popular vote every four years or when dissolved, and an upper house, the House of Councillors with 242 seats, whose popularly elected members serve six-year terms. There is universal suffrage for adults over 18 years of age, with a secret ballot for all elected offices. The Diet is dominated by the social liberal Democratic Party of Japan (DP) and the conservative Liberal Democratic Party (LDP). The LDP has enjoyed near continuous electoral success since 1955, except for a brief 11-month period between 1993 and 1994, and from 2009 to 2012. As of May 2017, it holds 294 seats in the lower house and 121 seats in the upper house.
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 he appoints and dismisses the Ministers of State. Following the LDP’s landslide victory in the 2012 general election, Shinzō Abe replaced Yoshihiko Noda as the Prime Minister on December 26, 2012 and became the country’s sixth prime minister to be sworn in during a span of six years. Although the Prime Minister is formally appointed by the Emperor, the Constitution explicitly requires the Emperor to appoint whoever is designated by the Diet.
Historically influenced by Chinese law, the Japanese legal system developed independently during the Edo period through texts such as Kujikata Osadamegaki. 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 the code remaining in effect with post–World War II modifications. 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; however, without specifically giving him the power to oppose legislation. Japan’s court system is divided into four basic tiers: the Supreme Court and three levels of lower courts. The main body of Japanese statutory law is called the Six Codes.
Japan consists of 47 prefectures, each overseen by an elected governor, legislature and administrative bureaucracy. Each prefecture is further divided into cities, towns and villages. 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.
Japan is the third largest national economy in the world, after the United States and China, in terms of nominal GDP, and the fourth largest national economy in the world, after the United States, China and India, in terms of purchasing power parity. As of 2014, Japan’s public debt was estimated at 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 the earthquake and tsunami in March 2011 caused the rating downgrade. The service sector accounts for three quarters of the gross domestic product.
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. As of 2010, Japan’s labor force consisted of some 65.9 million workers. Japan has a low unemployment rate of around four percent. Some 20 million people, around 17 per cent of the population, were below the poverty line in 2007. Housing in Japan is characterized by limited land supply in urban areas.
Japan’s exports amounted to US$4,210 per capita in 2005. As of 2012, Japan’s main export markets were China (18.1 percent), the United States (17.8 percent), South Korea (7.7 percent), Thailand (5.5 percent) and Hong Kong (5.1 percent). Its main exports are transportation equipment, motor vehicles, iron and steel products, semiconductors and auto parts. Japan’s main import markets as of 2012 were China (21.3 percent), the US (8.8 percent), Australia (6.4 percent), Saudi Arabia (6.2 percent), United Arab Emirates (5.0 percent), South Korea (4.6 percent) and Qatar (4.0 percent).
Japan’s main imports are machinery and equipment, fossil fuels, foodstuffs (in particular beef), chemicals, textiles and raw materials for its industries. By market share measures, domestic markets are the least open of any OECD country. Junichirō Koizumi‘s administration began some pro-competition reforms, and foreign investment in Japan has soared.
Japan ranks 27th of 189 countries in the 2014 Ease of doing business index and has one of the smallest tax revenues of the developed world. The Japanese variant of capitalism has many distinct features: keiretsu enterprises are influential, and lifetime employment and seniority-based career advancement are relatively common in the Japanese work environment. Japanese companies are known for management methods like “The Toyota Way“, and shareholder activism is rare.
Modern Japan’s economic growth began in the Edo period. Some of the surviving elements of the Edo period are roads and water transportation routes, as well as financial instruments such as futures contracts, banking and insurance of the Osaka rice brokers. During the Meiji period from 1868, Japan expanded economically with the embrace of the market economy. Many of today’s enterprises were founded at the time, and Japan emerged as the most developed nation in Asia. 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.
Growth slowed in the 1990s during the “Lost Decade” due to after-effects of the Japanese asset price bubble and government policies intended to wring speculative excesses from the stock and real estate markets. Efforts to revive economic growth were unsuccessful and further hampered by the global slowdown in 2000. The economy recovered 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.
Japan attracted 19.73 million international tourists in 2015 and increased by 21.8% to attracted 24.03 million international tourists in 2016. Tourism from abroad is one of the few promising businesses in Japan. Foreign visitors to Japan doubled in last decade and reached 10 million people for the first time in 2013, led by increase of Asian visitors.
In 2008, the Japanese government has set up Japan Tourism Agency and set the initial goal to increase foreign visitors to 20 million in 2020. In 2016, having met the 20 million target, the government has revised up its target to 40 million by 2020 and to 60 million by 2030.
Japan has 20 World Heritage Sites, including Himeji Castle, Historic Monuments of Ancient Kyoto and Nara. Popular tourist attractions include Tokyo and Hiroshima, Mount Fuji, ski resorts such as Niseko in Hokkaido, Okinawa, riding the shinkansen and taking advantage of Japan’s hotel and hotspring network.
For inbound tourism, Japan was ranked 16th in the world in 2015. In 2009, the Yomiuri Shimbun published a modern list of famous sights under the name Heisei Hyakkei (the Hundred Views of the Heisei period). The Travel and Tourism Competitiveness Report 2017 ranks Japan 4th out of 141 countries overall, which was the best in Asia. Japan gained relatively high scores in almost all aspects, especially health and hygiene, safety and security, cultural resources and business travel.
In 2016, 24,039,053 foreign tourists visited Japan. Neighbouring South Korea is Japan’s most important source of foreign tourists. In 2010, the 2.4 million arrivals made up 27% of the tourists visiting Japan. Chinese travelers are the highest spenders in Japan by country, spending an estimated 196.4 billion yen (US$2.4 billion) in 2011, or almost a quarter of total expenditure by foreign visitors, according to data from the Japan Tourism Agency.
The Japanese government hopes to receive 40 million foreign tourists every year by 2020
