Japan is an island country in East Asia. Located in the Pacific Ocean off the northeast coast of the Asian mainland, it is bordered to the west by the Sea of Japan and extends from the Sea of Okhotsk in the north to the East China Sea in the south. The Japanese archipelago consists of four major islands alongside 14,121 smaller islands. Japan is divided into 47 administrative prefectures and eight traditional regions, and around 75% of its terrain is mountainous and heavily forested, concentrating its agriculture and highly urbanized population along its eastern coastal plains. With a population of over 123 million as of 2025, it is the world's 11th most populous country. Tokyo is the country's capital and largest city.

The first known habitation of the archipelago dates to the Upper Paleolithic, with the beginning of the Japanese Paleolithic dating to c. 36,000 BC. Between the 4th and 6th centuries, its kingdoms were united under an emperor in Nara and later Heian-kyō. From the 12th century, actual power was held by military aristocrats known as shōgun and feudal lords called daimyō, enforced by warrior nobility named samurai. After rule by the Kamakura and Ashikaga shogunates and a century of warring states, Japan was unified in 1600 by the Tokugawa shogunate, which implemented an isolationist foreign policy. In 1853, an American fleet forced Japan to open trade to the West, which led to the end of the shogunate and the restoration of imperial power in 1868.
The Meiji period saw Japan pursue rapid industrialization, modernization, militarism, and overseas colonization. The country annexed Korea in 1910, invaded China in 1937, and attacked the U.S. and European colonial powers in 1941, thus entering World War II as an Axis power. After being defeated in the Pacific War and suffering the U.S. atomic bombings of Hiroshima and Nagasaki, Japan surrendered in 1945 and came under Allied occupation. It underwent rapid economic growth in the following decades and became one of the first major non-NATO allies of the U.S. Since the collapse of the Japanese asset price bubble in the early 1990s, it has experienced a prolonged period of economic stagnation referred to as the Lost Decades.
Japan is a constitutional monarchy with a bicameral legislature known as the National Diet. Widely considered a great power and the only Asian member of the G7, it maintains one of the world's strongest militaries but has constitutionally renounced its right to declare war. A developed country with one of the world's largest economies by nominal GDP, it is a global leader in the automotive, electronics, and robotics industries, in addition to making significant contributions to science and technology. It has one of the world's highest life expectancies, but is undergoing a population decline. The culture of Japan is well known around the world, particularly its popular culture as expressed in animation, art, comics, cuisine, fashion, films, music, television, and video games.
Etymology
The name for Japan in Japanese is written using the kanji 日本 and is pronounced Nihon or Nippon. Before 日本 was adopted in the early 8th century, the country was known in China as Wa (倭, changed in Japan around 757 to 和) and in Japan by the endonym Yamato. Nippon, the original Sino-Japanese reading of the characters, is favored for official uses, including on Japanese banknotes and postage stamps. Nihon is typically used in everyday speech and reflects shifts in Japanese phonology during the Edo period. The characters 日本 mean "sun origin", which is the source of the popular Western epithet "Land of the Rising Sun".
The name "Japan" is based on Min or Wu Chinese pronunciations of 日本 and was introduced to European languages through early trade. In the 13th century, Marco Polo recorded the Early Mandarin Chinese pronunciation of the characters 日本國 as Cipangu. The old Malay name for Japan, Japang or Japun, was borrowed from a southern coastal Chinese dialect and encountered by Portuguese traders in Southeast Asia, who brought the word to Europe in the early 16th century. The first version of the name in English appears in a book published in 1577, which spelled the name as Giapan in a translation of a 1565 Portuguese letter.
History
Prehistoric to classical history
Modern humans arrived in Japan around 38,000 years ago (~36,000 BC), marking the beginning of the Japanese Paleolithic. Around 14,500 BC (the start of the Jōmon period), a Mesolithic to Neolithic semi-sedentary hunter-gatherer culture characterized by pit dwelling and rudimentary agriculture emerged. Clay vessels from the period are among the oldest surviving examples of pottery. The Japonic-speaking Yayoi people later entered the archipelago from the Korean Peninsula, intermingling with the Jōmon people. The Yayoi period saw the introduction of innovative practices including wet-rice farming, a new style of pottery, and metallurgy from China and Korea. According to legend, Emperor Jimmu (descendant of Amaterasu) founded a kingdom in central Japan in 660 BC, beginning a continuous imperial line.
Japan first appears in written history in the Chinese Book of Han, completed in 111 AD, where it is described as having a hundred small kingdoms. A century later, the Book of Wei records that the kingdom of Yamatai (which may refer to Yamato) unified most of these kingdoms. Buddhism was introduced to Japan from Baekje (a Korean kingdom) in 552, but the development of Japanese Buddhism was primarily influenced by China. Despite early resistance, Buddhism was promoted by the ruling class, including figures like Prince Shōtoku, and gained widespread acceptance beginning in the Asuka period (592–710).
In 645, the government led by Prince Naka no Ōe and Fujiwara no Kamatari devised and implemented the far-reaching Taika Reforms. The Reform began with land reform, based on Confucian ideas and philosophies from China. It nationalized all land in Japan, to be distributed equally among cultivators, and ordered the compilation of a household registry as the basis for a new system of taxation. The true aim of the reforms was to bring about greater centralization and to enhance the power of the imperial court, which was also based on the governmental structure of China. Envoys and students were dispatched to China to learn about Chinese writing, politics, art, and religion.
The Jinshin War of 672, a bloody conflict between Prince Ōama and his nephew Prince Ōtomo, became a major catalyst for further administrative reforms. These reforms culminated with the promulgation of the Taihō Code, which consolidated existing statutes and established the structure of the central and subordinate local governments. These legal reforms created the ritsuryō state, a system of Chinese-style centralized government that remained in place for half a millennium.
The Nara period (710–784) marked the emergence of a Japanese state centered on the Imperial Court in Heijō-kyō (modern Nara). The period is characterized by the appearance of a nascent literary culture with the completion of the Kojiki (712) and Nihon Shoki (720), as well as the development of Buddhist-inspired artwork and architecture. A smallpox epidemic in 735–737 is believed to have killed as much as one-third of Japan's population. In 784, Emperor Kanmu moved the capital, settling on Heian-kyō (modern-day Kyoto) in 794. This marked the beginning of the Heian period (794–1185), during which a distinctly indigenous Japanese culture emerged. Murasaki Shikibu's The Tale of Genji and the lyrics of Japan's national anthem "Kimigayo" were written during this time.
Feudal era
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 by the Minamoto clan in the Genpei War, samurai Minamoto no Yoritomo established a military government at Kamakura. After Yoritomo's death, the Hōjō clan came to power as regents for the shōgun. 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. Go-Daigo was defeated by Ashikaga Takauji in 1336, beginning the Muromachi period (1336–1573). The succeeding Ashikaga shogunate failed to control the feudal warlords (daimyō) and a civil war began in 1467, opening the century-long Sengoku period ("Warring States").
During the 16th century, Portuguese traders and Jesuit missionaries reached Japan for the first time, initiating direct commercial and cultural exchange between Japan and the West (see Nanban trade and Nanban art). Oda Nobunaga used European technology and firearms to conquer many other daimyō; his consolidation of power began what was known as the Azuchi–Momoyama period. After the death of Nobunaga in 1582, his successor, Toyotomi Hideyoshi, unified the nation in the early 1590s and launched two unsuccessful invasions of Korea in 1592 and 1597.
Tokugawa Ieyasu served as regent for Hideyoshi's son Toyotomi Hideyori within the Council of Five Elders and used his position to gain political and military support. When open war broke out, Ieyasu defeated rival clans in the Battle of Sekigahara in 1600. He was appointed shōgun by Emperor Go-Yōzei in 1603 and established the Tokugawa shogunate at Edo (modern Tokyo). The shogunate enacted measures including buke shohatto, as a code of conduct to control the autonomous daimyō, 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). Modern Japan's economic growth began in this period, resulting in roads (Kaidō) and water transportation routes, as well as financial instruments such as futures contracts, banking and insurance of the Osaka rice brokers. The study of Western sciences (rangaku) continued through contact with the Dutch enclave in Nagasaki. The Edo period gave rise to kokugaku ("national studies"), the study of Japan by the Japanese.
Modern era
The United States Navy sent Commodore Matthew C. Perry to force the opening of Japan to the outside world. Arriving at Uraga with four "Black Ships" in July 1853, the Perry Expedition resulted in the March 1854 Convention of Kanagawa. Subsequent similar treaties with other Western countries brought economic and political crises. The resignation of the shōgun 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 (November 29, 1890), and assembled the Imperial Diet.
During the Meiji period (1868–1912), the Empire of Japan emerged as the most developed state in Asia and as 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, and annexed Korea in 1910. The Japanese population doubled from 35 million in 1873 to 70 million by 1935, with a significant shift to urbanization.
The early 20th century saw a period of Taishō democracy (1912–1926) overshadowed by increasing expansionism and militarization. World War I allowed Japan, which joined the side of the victorious Allies, to capture German possessions in the Pacific and China in 1920. The 1920s saw a political shift towards statism, a period of lawlessness following the 1923 Great Tokyo Earthquake, the passing of laws against political dissent, and a series of attempted coups.
This process accelerated in the 1930s, spawning several radical nationalist groups that shared a hostility to liberal democracy and a dedication to expansion in Asia. In 1931, Japan invaded China and occupied Manchuria, which led to the establishment of puppet state of Manchukuo in 1932; following international condemnation of the occupation, it resigned from the League of Nations in 1933. In 1936, Japan signed the Anti-Comintern Pact with Nazi Germany; the 1940 Tripartite Pact made it one of the Axis powers.
The Empire of Japan invaded other parts of China in 1937, precipitating the Second Sino-Japanese War (1937–1945). In 1940, the Empire 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, as well as on British forces in Malaya, Singapore, and Hong Kong, among others, beginning World War II in the Pacific. Throughout areas occupied by Japan during the war, numerous abuses were committed against local inhabitants. Many women were forced into sexual slavery.
After Allied victories 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. The war cost Japan millions of lives and many of its conquered territories, including de jure parts of Japan such as Korea, Taiwan, Karafuto, and the Kurils. The Allies, led by the United States, repatriated millions of Japanese settlers from their former colonies and military camps throughout Asia, largely eliminating the Empire of Japan and its influence over the territories it conquered. The Allies convened the International Military Tribunal for the Far East to prosecute Japanese leaders except the Emperor for Japanese war crimes.
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. A period of record growth propelled Japan to become the world's second-largest economy at that time; this ended in the mid-1990s after the popping of an asset price bubble, beginning the "Lost Decade" characterized by economic stagnation and low inflation. In 2011, Japan suffered one of the largest earthquakes in its recorded history—the Tōhoku earthquake—triggering the Fukushima Daiichi nuclear disaster. On May 1, 2019, after the historic abdication of Emperor Akihito, his son Naruhito became Emperor, beginning the Reiwa era (2019-).
Geography
Japan comprises 14,125 islands extending along the Pacific coast of Asia. It stretches over 3000 km (1900 mi) northeast–southwest from the Sea of Okhotsk to the East China Sea. The country's five main islands, from north to south, are Hokkaido, Honshu, Shikoku, Kyushu and Okinawa. The Ryukyu Islands, which include Okinawa, are a chain to the south of Kyushu. The Nanpō Islands are south and east of the main islands of Japan. Together they are often known as the Japanese archipelago. As of 2019[update], Japan's territory is 377,975.24 km2 (145,937.06 sq mi). Japan has the sixth-longest coastline in the world at 29,751 km (18,486 mi). Because of its far-flung outlying islands, Japan's exclusive economic zone is the eighth-largest in the world, covering 4,470,000 km2 (1,730,000 sq mi).
The Japanese archipelago is 67% forests and 14% agricultural. The primarily rugged and mountainous terrain is restricted for habitation. Thus the habitable zones, mainly in the coastal areas, have very high population densities: Japan is the 40th most densely populated country even without considering that local concentration. Honshu has the highest population density at 450 persons/km2 (1200/sq mi) as of 2010[update], while Hokkaido has the lowest density of 64.5 persons/km2 as of 2016[update]. As of 2014[update], approximately 0.5% of Japan's total area is reclaimed land (umetatechi). Lake Biwa is an ancient lake and the country's largest freshwater lake.
Japan is substantially prone to earthquakes, tsunami and volcanic eruptions because of its location along the Pacific Ring of Fire. It has the 17th highest natural disaster risk as measured in the 2016 World Risk Index. Japan has 111 active volcanoes. 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, which triggered a large tsunami.
Climate
The climate of Japan is predominantly temperate but varies greatly from north to south. The northernmost region, 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 region on Honshu's west coast, northwest winter winds bring heavy snowfall during winter. In the summer, the region 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. 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 and Nanpō Islands have a subtropical climate, with warm winters and hot summers. Precipitation is very heavy, especially during the rainy season. The main rainy season begins in early May in Okinawa, and the rain front gradually moves north. In late summer and early autumn, typhoons often bring heavy rain. According to the Environment Ministry, heavy rainfall and increasing temperatures have caused problems in the agricultural industry and elsewhere. The highest temperature ever measured in Japan, 41.8 °C (107.2 °F), was recorded on August 5, 2025.
Biodiversity
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. Japan has over 90,000 species of wildlife as of 2019[update], including the brown bear, the Japanese macaque, the Japanese raccoon dog, the small Japanese field mouse, and the Japanese giant salamander. There are 53 Ramsar wetland sites in Japan. Five sites have been inscribed on the UNESCO World Heritage List for their outstanding natural value.
Environment
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 concerns, the government introduced environmental protection laws in 1970. The oil crisis in 1973 also encouraged the efficient use of energy because of Japan's lack of natural resources.
Japan ranks 20th in the 2018 Environmental Performance Index, which measures a country's commitment to environmental sustainability. Japan is the world's fifth-largest emitter of carbon dioxide. As the host and signatory of the 1997 Kyoto Protocol, Japan is under treaty obligation to reduce its carbon dioxide emissions and to take other steps to curb climate change. In 2020, the government of Japan announced a target of carbon-neutrality by 2050. 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.
