⛩️ A History of Japan

What you’ll learn

1. The DialReplace the passive 'closed country opened by Perry' narrative with the course's through-line: Japan deliberately and repeatedly adjusted its own openness in both directions for a thousand years — and set the course's boundaries.The familiar story casts Japan as passive: it is closed, opened, awakened, with all the verbs belonging to someone else. The dial metaphor restores agency — maximum open in the seventh century, turned down in 894, wide open in the sixteenth, throttled in the 1630s, forced in 1853 (the one genuine exception), and thrown to maximum in 1868. A closed country could not have done that. The course owns the past and hands the present, and the Second World War in the Pacific, to the sibling courses that treat them at proper length.
2. Borrowing a Civilisation on PurposeUnderstand the seventh-century adoption of the Tang model as a sovereign, deliberate, and selectively edited import — the dial's first turn to maximum.Looking at Tang China, the Yamato rulers decided to reconstruct their country on its model: Chinese characters to write an unrelated language, Buddhism, the ritsuryō legal codes, the calendar and court ranks, and grid capitals at Nara (710) and Heian-kyō (794). Embassies carried students and monks on genuinely dangerous voyages for over two centuries. Nobody compelled any of it. And they edited: the civil service examination — China's solution to hereditary elites — was adopted in form and gutted in practice by a hereditary elite, which is a choice about what to copy rather than a failure to copy.
3. The First ClosingShow that the 894 cancellation of the Tang embassies produced Japan's classical age rather than decline — the first proof that closing is not stagnating.Sugawara no Michizane recommended cancelling the embassy in 894, arguing the Tang was in disorder and the voyage not worth its cost; the court agreed and the embassies never resumed. What followed was the Heian period, when Japan stopped being a Chinese cultural province. Kana — a phonetic script that could finally write Japanese as Japanese — was dismissed as onnade, 'women's hand'. So men wrote formal documents in a foreign language while women, excluded from prestige, wrote in the script that captured actual thought, and produced The Tale of Genji (c.1008) and The Pillow Book.
4. The Emperor Who Doesn't RuleExplain the shogunate structure — emperor reigns, shogun rules — as a mechanism separating legitimacy from power, and flag the sacred idle office that Meiji will later weaponise.As the Heian court lost the provinces to armed men, the samurai emerged as a class. In 1185 Minamoto no Yoritomo had the emperor appoint him shōgun and governed from Kamakura, 250 miles away. The structure lasted nearly 700 years across three shogunates because it makes coups survivable — the emperor simply appoints the winner and the fiction holds. It went recursive: Hōjō regents ruled for figurehead shoguns appointed by figurehead emperors sometimes controlled by retired emperors. A permanent sacred office that never acts can never fail — and is available for reuse in 1868.
5. The Wind That Became a StoryTreat the Mongol invasions honestly — luck and weather alongside competent defence — and distinguish the kamikaze story's long-run work from the shogunate's immediate fiscal ruin.Kublai Khan's fleets of 1274 and 1281 were wrecked by storms; marine archaeology off Takashima supports the picture, alongside real Mongol logistical problems and poorly built ships. Japan was, in significant part, lucky twice. The storms were named kamikaze and became evidence for a proposition — that Japan is divinely protected and cannot be conquered — the same mechanism as China's Mandate of Heaven in different clothes, with its twentieth-century consequence belonging to the war course. The immediate consequence: a defensive war yields no loot, so the régime that saved Japan bankrupted itself rewarding samurai and fell within fifty years.
6. The Country at War With ItselfCover the Sengoku collapse and the 1543 arrival of firearms, then weigh Perrin's 'giving up the gun' thesis against its critics without adopting either wholesale.From 1467 Japan had no central authority for roughly a century — emperors sold calligraphy to eat. Portuguese guns arrived by accident in 1543 and were being copied in quantity within a decade; by 1600 Japan's firearm production stood comparison with Europe's. Then the Tokugawa unified the country and guns receded. Perrin (1979) argued Japan uniquely abandoned a superior weapon for status reasons; critics counter that the Tokugawa monopolised rather than banned guns, that rural use continued, and that the wars simply stopped — peace mistaken for policy. The modified observation survives: the peace itself was engineered.
7. Sakoku Was a Policy, Not an AccidentExplain the 1630s edicts as considered statecraft with stated reasons, and replace 'isolation' with the four managed gateways of Nagasaki, Tsushima, Satsuma and Matsumae.The Tokugawa expelled the Portuguese, banned Christianity, and forbade subjects to leave — not from xenophobia but because Christian daimyō owed loyalty to Rome above the shogun, western lords grew rich and armed on foreign trade, and Iberian conduct in the Philippines had demonstrated the missionaries-then-soldiers pattern; Shimabara (1637–38) confirmed it. But Japan was never closed: four licensed doors ran throughout — the Dutch and Chinese at Nagasaki, Korea via Tsushima, the Ryukyus (and indirectly China) via Satsuma, the Ainu and the north via Matsumae. Even 'sakoku' is an 1801 Japanese rendering of the German physician Kaempfer's description.
8. What Two Centuries of Peace BuiltDemonstrate that the Tokugawa 'closure' produced an urban, literate, commercially sophisticated society that was watching the West deliberately through one door — which explains the speed of what followed.Two and a half centuries of peace made Edo probably the world's largest city (~1 million by around 1720), with Osaka and Kyoto also major. Terakoya schools, commercial publishing, lending libraries and a mass reading public created what Berry describes as an early modern information society — though specific literacy percentages rest on thin data and deserve caution. Ukiyo-e were cheap mass-market prints that later redirected European painting; Van Gogh copied Hiroshige directly. Through Dejima, rangaku scholars tracked European science — the 1774 Kaitai Shinsho was translated after a dissection proved the Dutch atlas right and the Chinese texts wrong.
9. The ShockIdentify precisely what Perry's arrival broke — the shogun's sole legitimating function — and trace how 'expel the barbarians' inverted into total importation.Perry arrived in 1853 with four ships and returned in 1854 with nine. The Dutch had warned the shogunate he was coming; the shock was not foreigners but steamships moving against the wind under guns that outranged everything Japan had. The shogun's title means roughly 'barbarian-subduing generalissimo' — his one legitimating job — and he had to consult the daimyō, announcing that he did not know what to do. Satsuma and Chōshū then fought Westerners at Kagoshima (1863) and Shimonoseki (1864), lost, and concluded that expulsion required strength, and strength required learning everything the West knew.
10. Meiji: A Country Rebuilds ItselfJustify the claim that Meiji was the most successful deliberate self-transformation any state has attempted — through the Charter Oath, the Iwakura Mission's selective shopping, and the reasons it worked where others failed.In about forty years Japan abolished the class system, the domains and the samurai (by samurai), built a conscript army, a navy, a school system, railways, a central bank, a constitution (1889) and a parliament (1890). The Charter Oath's fifth article — knowledge sought throughout the world to strengthen imperial rule — makes openness explicitly an instrument. In 1871 the three-year-old government sent half its leadership abroad for 22 months, and shopped selectively: French then German army, British navy, German constitution. It worked because Japan was already a going concern, small and coherent, had a sacred idle emperor available as authority, had China as a worked example, and was led by young men with nothing invested in the old order. By 1905 it defeated Russia.
11. The Logic That Kept RunningExplain how Meiji's defensive reasoning extended into empire — and hand the Second World War in the Pacific to the sibling course that owns it, while being explicit that explanation is not exculpation.Openness was an instrument and strength was the goal, set by four ships in 1853. In the late nineteenth century every strong state had an empire — that was what the category consisted of — so Japan took Taiwan (1895), annexed Korea (1910), and took Germany's Pacific holdings after WWI. At Versailles in 1919 its racial equality clause won a majority and was struck down by Wilson on a unanimity ruling. The logic that saved Japan in 1868 is the logic that destroyed it in 1945, having kept running past the point where it was defensive. The war itself belongs to the course that can give its victims proper place; explaining how a state came to act is not excusing what it did.
12. The Dial After the FireClose the through-line by reading Article 9 as an imposition that became a choice, and review fourteen centuries as one continuously-asked question.The 1946 constitution was drafted by Americans in about a week and contains Article 9, renouncing war and war potential — the only such clause in any major state's constitution, and never amended. It is the second and last time the dial moved by a foreign hand, and as with the first, Japan then took hold of it: the occupation ended in 1952, and through the Cold War and heavy American pressure to rearm, Japan has chosen for seventy-four years not to amend it. An imposition kept voluntarily that long is a decision. The answers across fourteen centuries changed completely; the fact that somebody was deciding never did.
