San Francisco Peace Treaty of 1951

The San Francisco Peace Treaty, 1951 converted Japan from an occupied former enemy state into a sovereign state at peace with the Allied parties. It restored Japan's international legal personality while imposing territorial renunciations, war-related obligations and a framework for post-war security relations.

Restoration of peace and sovereignty

Signed on 8 September 1951 and effective from 28 April 1952, the treaty ended the state of war between Japan and each Allied party for which it entered into force. Under Article 1, the Allies recognized the full sovereignty of the Japanese people over Japan and its territorial waters.

• Article 6 required Allied occupation forces to withdraw within 90 days, while permitting foreign forces to remain under bilateral or multilateral agreements.
• Article 5 recognized Japan's inherent right of individual or collective self-defence and its freedom to enter collective security arrangements.

Territorial and legal settlement

Under Article 2, Japan recognized Korea's independence and renounced claims to Taiwan and the Pescadores, the Kurile Islands, part of Sakhalin, former Pacific mandates, Antarctic territory, and the Spratly and Paracel Islands. Several renunciations did not specify the recipient state, leaving questions that later contributed to territorial disputes.

• Under Article 11, Japan accepted the judgments of the International Military Tribunal for the Far East and other Allied war-crimes courts.
• Article 14 acknowledged Japan's obligation to make reparations, while recognizing that its resources were insufficient to compensate all damage fully.

Scope and India's position

The settlement was not universal because the Soviet Union did not sign and neither Chinese government became a party. India also stayed outside this treaty and concluded a separate Treaty of Peace with Japan, 1952, through which normal relations were restored and India waived reparations claims.
