Japan

By the 3rd and 4th centuries CE, a dominant polity centered on the Yamato plain of central Honshu had begun to extend its authority over rival clans. Its rulers built the colossal keyhole-shaped kofun tomb mounds that give the era its archaeological name and claimed sacred descent from the sun goddess Amaterasu, a lineage that would underpin imperial legitimacy for all of subsequent Japanese history. The mythical narratives later compiled in the Kojiki and Nihon shoki projected this dynasty back to the legendary Emperor Jimmu in 660 BCE, but the verifiable state took shape only in these centuries.

The Asuka period, named for the region south of present-day Nara where the court resided, opened with the transformative arrival of Buddhism, traditionally dated to the mid-6th century via the Korean kingdom of Baekje. After fierce factional struggle, the powerful Soga clan secured the new religion's place at court. Under the regent Prince Shotoku, Japan deliberately remodeled itself on the Chinese pattern: he dispatched embassies to the Sui court, promoted Buddhism, and is credited with the Seventeen-Article Constitution of 604, a Confucian-Buddhist statement of governing ethics.

The momentum toward centralization culminated in the Taika Reform initiated in 645, which sought to reorganize land and population under direct imperial control on the Chinese model. Over the following decades these efforts hardened into the ritsuryo system of legal codes and bureaucratic government, laying the institutional foundation for the classical Japanese state that the Nara capital would soon embody.

Figures of the era

In 710 the court established Japan's first enduring capital at Heijo-kyo (Nara), laid out on a grid modeled on the Tang Chinese capital of Chang'an. The Nara period saw the consolidation of Buddhist institutions as instruments of state, epitomized by the casting of the great bronze Buddha at Todai-ji, and the compilation of the foundational chronicles Kojiki and Nihon shoki along with the Man'yoshu poetry anthology. The growing wealth and political weight of the great monasteries, however, prompted the court to seek distance from them.

In 794 Emperor Kanmu moved the capital to Heian-kyo, modern Kyoto, inaugurating the Heian period, which lasted until 1185 and is regarded as the classical high point of Japanese aristocratic culture. The Chinese-style centralized order gradually loosened as tax-exempt private estates, the shoen, expanded at the expense of the public domain. Real power flowed to the Fujiwara family, who dominated the court for generations by marrying their daughters to emperors and ruling as regents.

Sheltered behind these political arrangements, the Heian aristocracy cultivated an exquisite court culture. The development of the kana syllabaries freed Japanese writing from exclusive reliance on Chinese characters and enabled a flowering of vernacular literature, above all Murasaki Shikibu's The Tale of Genji, often called the world's first novel. By the late Heian period, provincial warrior houses, the Taira and Minamoto, had grown powerful enough to intervene in court politics, and their rivalry would bring the classical age to a violent close.

Figures of the era

Victory in the Genpei War made Minamoto Yoritomo the supreme military authority in Japan. Establishing his government, the bakufu, at Kamakura, he was named shogun in 1192, inaugurating a dual structure in which the emperor reigned in Kyoto while the shogun ruled in fact. The Kamakura shogunate firmly entrenched feudal relations between warrior lords and their retainers and, after Yoritomo's death, real authority shifted to the Hojo regents. The regime's most celebrated achievement was repelling the Mongol invasions launched by Kublai Khan in 1274 and 1281, when storms remembered as the kamikaze, or divine winds, helped destroy the invading fleets.

The Kamakura shogunate fell in 1333, and after a brief imperial restoration Ashikaga Takauji established a new shogunate in 1338, ruling from the Muromachi district of Kyoto. The Muromachi period was politically turbulent, divided early on between rival northern and southern imperial courts, yet culturally luminous. Under Ashikaga patronage Zen Buddhism shaped an aesthetic of restraint that produced ink painting, the tea ceremony, Noh theater, and landmark architecture such as Kyoto's Golden and Silver Pavilions.

Ashikaga authority was always thinner than the Kamakura precedent, resting on coalitions of regional warlords. When the Onin War erupted in 1467, devastating Kyoto and fracturing central control, the shogunate became largely powerless. Japan dissolved into the warring-states condition that would define the following century, even as the formal Muromachi shogunate endured until 1573.

Figures of the era

From the late 15th century Japan was riven by the Sengoku, or warring-states, period, in which independent daimyo fought for territory amid the ruins of central authority. The introduction of European firearms and the arrival of Portuguese traders and Jesuit missionaries from the 1540s added new forces to the conflict. Out of this chaos came the three unifiers: Oda Nobunaga, who broke the power of rival warlords and militant Buddhist orders; Toyotomi Hideyoshi, a commoner who completed the unification of the provinces by 1590 and launched ill-fated invasions of Korea; and finally Tokugawa Ieyasu.

Ieyasu's decisive victory at the Battle of Sekigahara in 1600 left him master of Japan, and in 1603 he was named shogun, founding the Tokugawa shogunate based at Edo (modern Tokyo). The Tokugawa regime built a durable order: a rigid status hierarchy of samurai, peasants, artisans, and merchants; the alternate-attendance system that bound the daimyo to the shogun; and a guarded reverence for the still-powerless imperial court at Kyoto.

Fearing the destabilizing effect of Christianity and foreign intrigue, the shogunate enforced the sakoku policy from the 1630s, expelling missionaries, banning Japanese from going abroad, and confining foreign trade largely to Dutch and Chinese merchants at Nagasaki. The result was more than two centuries of near-total peace, during which a vibrant urban and merchant culture flourished, producing kabuki theater, ukiyo-e woodblock prints, and haiku poetry. This stability held until 1853, when the arrival of Commodore Matthew Perry's American squadron forced Japan open and set in motion the shogunate's collapse.

Figures of the era

The forced opening of Japan exposed the Tokugawa order as unable to defend the country, and reformist samurai rallied behind the slogan of restoring imperial rule. In a coup in Kyoto in January 1868, they proclaimed the young Emperor Meiji ruler in his own right and abolished the shogunate. The Meiji Restoration was less a return to the past than a revolution from above: over the following decades the leadership dismantled the feudal domains, abolished the legal privileges of the samurai class, and introduced conscription, compulsory education, a national tax system, and a Western-style constitution in 1889.

Japan industrialized with extraordinary speed, building railways, factories, a modern army and navy, and the institutions of a centralized state. Determined to win recognition as a great power and to avoid the colonial subjugation suffered elsewhere in Asia, Japan also turned outward. Victory in the First Sino-Japanese War of 1894-1895 and, more startlingly, in the Russo-Japanese War of 1904-1905 announced its arrival as an imperial power, and it annexed Korea in 1910.

In the 1930s, economic strain and an increasingly autonomous military pushed Japan toward expansionist aggression, beginning with the seizure of Manchuria in 1931 and full-scale war with China from 1937. Allied with Nazi Germany and Fascist Italy, Japan attacked Pearl Harbor in December 1941, opening the Pacific War. After early conquests across Southeast Asia and the Pacific, the tide turned, and the war ended in 1945 with American firebombing of Japanese cities, the atomic bombings of Hiroshima and Nagasaki, the Soviet entry into the war, and Japan's surrender.

Figures of the era

From 1945 to 1952 Japan was occupied by the Allies under General Douglas MacArthur, who oversaw sweeping reforms: the dismantling of the military, land redistribution, the breakup of the great industrial combines, women's suffrage, and the trial of war leaders. The centerpiece was a new constitution that took effect in 1947, transforming the emperor into a symbol of the state, establishing popular sovereignty and a parliamentary democracy, and renouncing war and the maintenance of war potential in its famous Article 9.

Japan regained full sovereignty with the Treaty of San Francisco, signed in 1951 and effective in 1952, which ended the occupation while binding Japan closely to the United States through a security alliance. Freed to concentrate on reconstruction, Japan experienced a postwar economic miracle: decades of rapid growth that, by the 1960s and 1970s, made it one of the largest economies in the world, a leader in automobiles, electronics, and advanced manufacturing.

The collapse of an asset price bubble in the early 1990s ushered in a prolonged period of slow growth and deflation. In the 21st century Japan has continued as a stable, affluent democracy and a major global economy, while contending with an aging and shrinking population and recurring natural disasters, including the 2011 Tohoku earthquake, tsunami, and Fukushima nuclear accident. Its imperial institution endures: in 2019 Emperor Akihito abdicated in favor of his son Naruhito, opening the Reiwa era.
