More recent major quakes are the 1995 Great Hanshin earthquake and the 2011 Tōhoku earthquake, which triggered a large tsunami. Destructive earthquakes, often resulting in tsunami, occur several times each century; the 1923 Tokyo earthquake killed over 140,000 people. As of 2014update, approximately 0.5% of Japan’s total area is reclaimed land (umetatechi). Honshu has the highest population density at 450 persons/km2 (1200/sq mi) as of 2010update, while Hokkaido has the lowest density of 64.5 persons/km2 as of 2016update. The Ryukyu Islands, which include Okinawa, are a chain to the south of Kyushu. In 2011, Japan suffered one of the largest earthquakes in its recorded history—the Tōhoku earthquake—triggering the Fukushima Daiichi nuclear disaster.

The Ryukyu and Nanpō Islands have a subtropical climate, with warm winters and hot summers. Precipitation is not heavy, but the islands usually develop deep snowbanks in the winter. The northernmost region, Hokkaido, has a humid continental climate with long, cold winters and very warm to cool summers.
Statutory law originates in the legislature, and the constitution requires that the emperor promulgate legislation passed by the Diet without giving him the power to oppose legislation. Japan is a unitary state and constitutional monarchy in which the power of the emperor (Tennō) is limited to a ceremonial role. 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.

• 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.
• As of 2014update, approximately 0.5% of Japan’s total area is reclaimed land (umetatechi).
• In 645, the government led by Prince Naka no Ōe and Fujiwara no Kamatari devised and implemented the far-reaching Taika Reforms.

In 645, the government led by Prince Naka no Ōe and Fujiwara no Kamatari devised and implemented the far-reaching Taika Reforms. 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. 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. 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. 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 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.
Payment for personal medical services is offered through a universal health insurance system that provides relative equality of access, with fees set by a government committee. The Programme for International Student Assessment (PISA) coordinated by the OECD ranks the knowledge and skills of Japanese 15-year-olds as the third best in the world. Other minority religions include Hinduism, Judaism, and Baháʼí Faith, as well as the animist beliefs of the Ainu. In 2018, there were an estimated 105 mosques and 200,000 Muslims in Japan, 43,000 of which were Japanese nationals. Immigration and birth incentives are sometimes suggested as a solution to provide younger workers to support the nation’s aging population. The changes in demographic structure have created several social issues, particularly a decline in the workforce population and an increase in the cost of social security benefits.

• Historically influenced by Chinese law, the Japanese legal system developed independently during the Edo period through texts such as Kujikata Osadamegaki.
• 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.
• Japan has the highest ratio of public debt to GDP among advanced economies, with a national debt estimated at 248% relative to GDP as of 2022update.
• Japan has a population of over 123 million, of whom nearly 120 million are Japanese nationals (2024 estimates).
• 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.

Executive power is instead wielded by the prime minister and the Cabinet, whose sovereignty is vested in the Japanese people. In 2020, the government of Japan announced a target of carbon-neutrality by 2050. Japan ranks 20th in the 2018 Environmental Performance Index, which measures a country’s commitment to environmental sustainability. Responding to rising concerns, the government introduced environmental protection laws in 1970. Japan has nine forest ecoregions which reflect the climate and geography of the islands.
The Jinshin War of 672, a bloody conflict between Prince Ōama and his nephew Prince Ōtomo, became a major catalyst for further administrative reforms. 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. 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). A century later, the Book of Wei records that the kingdom of Yamatai (which may refer to Yamato) unified most of these kingdoms. The Yayoi period saw the introduction of innovative practices including wet-rice farming, a new style of pottery, and metallurgy from China and Korea. Clay vessels from the period are among the oldest surviving examples of pottery.

Government and politics

In 1936, Japan signed the Anti-Comintern Pact with Nazi Germany; the 1940 Tripartite Pact made it one of the Axis powers. 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. The Japanese population doubled from 35 million in 1873 to 70 million by 1935, with a significant shift to urbanization. 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.
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). 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. When open war broke out, Ieyasu defeated rival clans in the Battle of Sekigahara in 1600. 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. 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).
