Japan: The Emperor, the Shogun, and the Modern State

A classical court culture, seven centuries of samurai rule, two and a half centuries of isolation, a headlong modernisation after 1868, imperial war and defeat, and a postwar economic transformation

An old monarchy and a new democracy

Japan is an archipelago off the eastern edge of Asia, mountainous, seismic, and — by the standards of most large nations — strikingly homogeneous. Its emperor sits at the head of what tradition holds to be the world's oldest continuous hereditary monarchy, though for most of Japanese history the throne held little real power. The pattern that defines the country's past is that split: a ceremonial sovereign in one place, and the people who actually governed — regents, then shoguns, then a modern state — somewhere else.

Court and cloister

Wet-rice farming and metalworking arrived from the mainland around 300 BCE, and by the 5th century CE a state centred on the Yamato plain had emerged. Buddhism and Chinese writing came via Korea in the 6th century, and Japan built a centralised government modelled on Tang China, with permanent capitals at Nara and then Kyoto.

The first shogunate was founded at Kamakura in 1192, beginning roughly seven centuries of military government. It repelled two Mongol invasions, saved partly by typhoons. The later Ashikaga shogunate presided over a brilliant Zen-influenced culture but lost control of the provinces, and Japan collapsed into the century-long "Warring States" period. Portuguese traders arrived in 1543 with firearms, and Jesuit missionaries soon after; Christianity gained hundreds of thousands of converts before it was banned.

Isolation

Three warlords reunified Japan in succession, the last of them Tokugawa Ieyasu, who won the Battle of Sekigahara in 1600 and founded the shogunate that ruled from Edo — now Tokyo — for 250 years. The Tokugawa order brought internal peace, a rigid class system, and near-total closure to the outside world: Christianity was suppressed, and foreign contact was reduced to a single Dutch trading post at Nagasaki. Edo grew to around a million people, with a lively urban culture of kabuki theatre and woodblock prints.

The opening, and the Meiji Restoration

In 1853 American warships under Commodore Matthew Perry arrived demanding trade. Japan, aware of what the Opium Wars had done to China, signed a series of unequal treaties — a humiliation that discredited the shogunate.

In 1868 reformist samurai from the outer domains overthrew the Tokugawa and "restored" the young Emperor Meiji. They then dismantled the feudal system, abolished their own samurai class, and built a conscript army, a modern navy, railways, industry, universal schooling and a constitution — making Japan the first non-Western country to industrialise. It defeated China in 1895 and Russia in 1905, annexed Korea in 1910, and became an imperial power.

War and defeat

Brief liberal trends in the 1920s gave way, amid the Depression, to military domination. Japan seized Manchuria in 1931, invaded China in 1937 with immense brutality, and, after a US oil embargo, attacked Pearl Harbor in December 1941.

Occupation and the miracle

The US-led occupation demilitarised Japan and imposed a new constitution in 1947, renouncing war, giving women the vote, and reducing the emperor to a symbol. The Cold War then made Japan a key American ally, with US bases concentrated on Okinawa. Under the Liberal Democratic Party, in power almost continuously since 1955, Japan became the world's second-largest economy through state-guided industry — cars, electronics, steel — symbolised by the bullet train and the 1964 Tokyo Olympics.

Since the bubble collapsed, Japan has managed stagnation, the highest public debt in the developed world, and a falling population — its numbers peaked around 2008 — alongside disasters like the 2011 earthquake, tsunami and Fukushima meltdown. It remains a wealthy, orderly, high-technology democracy, now cautiously rebuilding its military as tensions with China and North Korea rise.

What Japan carries

Japan's history turns on borrowing and closing: it took writing, Buddhism and statecraft from China, then sealed itself off for 250 years; it took industry, law and militarism from the West after 1868, used them to build an empire, and lost everything in 1945; and it then rebuilt as a pacifist democracy and an economic giant. The through-line is a strong, cohesive society repeatedly remaking itself around a symbolic throne.
