History

Historical Context

Japan’s post-war security framework began with the 1954 Mutual Defense Assistance Agreement, later deepened by the 1960 Treaty of Mutual Cooperation that tied U.S. forces to Japan’s defense. After the 2024 Tokyo talks and the 2025 Japan-U.S.–Philippines pledge, Canberra’s August 2026 deal lets Japan test hypersonic missiles in Australia, building on an alliance that hosts about 55,000 U.S. troops in Japan.
