Japan and the United States Resume Diplomatic Relations

Since Japan's surrender in 1945, the Allied occupation had exercised authority over the country's political and economic reconstruction. Under General Douglas MacArthur's command, occupation policies included demilitarization, constitutional change, and land reform. As the Cold War intensified, American attention increasingly turned toward economic recovery and Japan's place in regional security. The Korean War added urgency by making Japan a principal supply base for United Nations forces. [1]

Japan’s chargé d’affaires, Ryuji Takeuchi, presented his credentials to Secretary of State Dean Acheson on 28 April 1952. That day the peace treaty took effect, normal diplomatic relations resumed, and the Allied occupation authority dissolved. Nearly seven years of occupation had ended. [3] [2]

The settlement had been negotiated in San Francisco the previous year. President Harry Truman announced the end of the state of war, and Japan regained the conduct of its foreign relations. The embassy opening in Tokyo came later: American ambassador Robert Murphy presented his credentials on 9 May. [3] [2]

American forces stayed. A separate security treaty took effect alongside the peace settlement, allowing the United States to keep troops in and around Japan after its authority as an occupying power had ended. [2]
