# Japanese History Hub Japan is the only country the United States has occupied, disarmed, rewritten the constitution of, and then spent seventy years asking to rearm. That contradiction is the whole subject. The pacifist clause the Americans wrote in 1946 is the clause American officials have pressed Japan to work around since roughly 1950. Every Japanese debate about defence since has been conducted in a constitutional framework imposed by the country now urging its revision — which gives Japanese politics a recursive quality that outside commentary usually flattens. > [!note] Two Japan pages > This hub covers Japanese history and politics. `Foreign Influence/Japan.md` covers Japanese lobbying and influence operations in Washington. Different subjects, deliberately separate. --- ## The Inheritance **Meiji.** The 1868 Meiji Restoration is the fastest state-directed modernization in history: a feudal order that in four decades built an industrial economy, a conscript army, and a navy that destroyed Russia's at Tsushima in 1905 — the first defeat of a European power by an Asian one in the modern era. It is the founding case for the argument that modernization does not require Westernization, and it is invoked to this day by states that want the technology without the politics. **Empire and war.** Taiwan in 1895, Korea in 1910, Manchuria in 1931, China in 1937, Pearl Harbor in 1941. The atrocity record — Nanjing, the comfort women system, Unit 731, the treatment of prisoners — is documented and remains the live substance of Japan's relationships with China and South Korea eighty years on. Japanese governments have issued apologies; revisionist currents within the governing party have periodically undercut them; the Yasukuni Shrine visit is the recurring flashpoint. See [[World War II]]. **The occupation.** The 1947 constitution was drafted principally by Americans in about a week. **Article 9** renounces war and the maintenance of land, sea and air forces. It has never been amended. The Self-Defense Forces exist through reinterpretation rather than revision — a seventy-year exercise in constitutional construction that is the closest international analogue to the American debates over executive power the vault tracks. Then the reversal: as the Cold War set in, American policy shifted from demilitarizing Japan to rebuilding it as an anti-communist anchor. Purged wartime officials returned to public life. Nobusuke Kishi, a Class A war-crimes suspect who was never tried, became prime minister in 1957. He is [[Sanae Takaichi]]'s ideological lineage and Shinzo Abe's grandfather. ## Takaichi **[[Sanae Takaichi]] became Japan's first female prime minister on 21 October 2025**, succeeding Shigeru Ishiba. She is from the LDP's nationalist right — an Abe protégée, a Yasukuni visitor, and a constitutional revisionist. Her arrival broke a 26-year alliance: **Komeito, the Buddhist-backed party that had governed with the LDP since 1999, ended the partnership over her leadership.** The Japan Innovation Party (Ishin) replaced it. Then she gambled. Takaichi dissolved the lower house on 23 January 2026 and called a snap election for **8 February 2026**. **The LDP won 316 of 465 seats — the most ever won by a single party in the Japanese lower house.** With Ishin's 36, the coalition holds **352 seats, roughly 75%** — well past the two-thirds threshold required to initiate constitutional revision. For the first time since 1947, a government committed to amending Article 9 has the parliamentary arithmetic to try. ## The China Crisis On **7 November 2025 Takaichi told the Diet that a Chinese attack on Taiwan "could constitute" a survival-threatening situation for Japan** — the legal formula that permits collective self-defence under the 2015 security legislation. It was the most explicit statement any Japanese premier has made about defending Taiwan. **She has never retracted it.** What followed is the most serious deterioration in China–Japan relations since normalization: | Date | Event | |---|---| | 2025-11-08 | China's consul general in Osaka posts that Takaichi's "dirty neck" should be cut off; later deleted | | 2025-11-14 | Chinese travel advisory against Japan | | 2025-12-06/07 | Chinese J-15s lock fire-control radar on Japanese F-15s near the Miyako Strait | | 2025-12-09 | Joint Russia–China bomber patrol through the Miyako Strait | | 2026-01 | Rare-earth export restrictions; pandas repatriated from Ueno Zoo | | 2026-06 | **Zero terbium and dysprosium oxide exports to Japan** | Tourism arrivals fell **45–61% year-on-year** every month from December 2025 to March 2026. Estimated economic damage runs $9–11 billion. See [[Critical Minerals]]. **The American response is the part worth noticing.** The US ambassador condemned the consul general's remarks and B-52s flew with Japanese fighters in December 2025. But **Trump personally has been notably quiet**, and Xi told him on 24 November 2025 that the postwar order including Taiwan's status should be upheld. Japan's prime minister made an explicit commitment to Taiwan's defence and absorbed a year of Chinese economic coercion for it, while the American president said very little. ## The Alliance in 2026 **Defence spending.** A record FY2026 budget of roughly $58 billion was approved in December 2025. As of April 2026 actual spending sits at **1.9% of GDP — just short of the 2% target** Takaichi accelerated. Japan approved a further five years of host-nation support for the US military presence. **Missiles.** The Army's **Typhon** launcher first deployed to Japan at MCAS Iwakuni in September 2025 and returned in 2026 to Kanoya Air Base in Kyushu. China calls it a "strategic offensive weapon"; Chinese analysts note that a Kyushu-based Tomahawk ranges Shanghai. See [[INF Treaty]] — this is the weapons class the treaty abolished. **Trade.** The July 2025 framework set a 15% inclusive tariff plus a $550 billion Japanese investment vehicle. After the Supreme Court voided the IEEPA structure, **Japan confirmed on 22 February 2026 that it would keep the investment pledge anyway** and asked not to be disadvantaged under the replacement rules. Since 24 July 2026 Japan has faced the [[Section 301 Forced Labor Tariffs]], which set a **combined ceiling of 12.5%**: each product pays the higher of 12.5% or its normal MFN rate, so the duty is not stacked on top of existing tariffs (Steptoe; Holland & Knight, July 2026). South Korea and Switzerland are in the same tier. It is no longer a negotiated bilateral rate at all. That is a striking piece of alliance management: honouring a $550 billion commitment made under a legal instrument that no longer exists. The new ceiling is actually lower than the 15% the deal specified, but Washington set it alone, under a statute it can revise without asking Tokyo. ## Why This Folder Exists Japan is the alliance case that runs opposite to Germany's, and reading them together is the point. Both are American-designed postwar democracies with constitutional constraints the US wrote. Both face an adversary the US names as the principal threat. In 2026 Germany — see [[German History Hub]] — questioned American policy on Iran and lost 5,000 troops and a missile deployment. Japan committed to Taiwan's defence, absorbed Chinese economic coercion, kept a $550 billion investment pledge with no legal basis, and got a 12.5% tariff ceiling that Washington set unilaterally. Neither obedience nor independence reliably purchased anything. What Japan bought is the option to keep the relationship intact while quietly acquiring the capability to act without it — the same conclusion European states reached by a different route through the [[Coalition of the Willing]]. The [[Quadrilateral Security Dialogue]] is where this becomes concrete. Foreign Policy's April 2026 assessment flagged the risk that the Quad is replaced by narrower Australia–India–Japan trilaterals that exclude the United States. Japan is the hinge of that arrangement. --- ## See Also - [[Sanae Takaichi]] — the first female prime minister and the revision majority - [[World War II]] — the empire, the war, and the occupation - [[Quadrilateral Security Dialogue]] · [[AUKUS]] · [[G7]] · [[Trans-Pacific Partnership]] - [[Chinese History Hub]] — the adversary and the historical grievance - [[German History Hub]] — the other American-designed postwar democracy - [[INF Treaty]] — the missile class now deployed in Kyushu - [[Critical Minerals]] — the rare-earth coercion - [[World History Hub]]
