Lytton Report

The Lytton Report (リットン報告書, Ritton Hōkokusho) refers to the findings of the Lytton Commission, entrusted in 1931 by the League of Nations in an attempt to evaluate the Mukden Incident, which was used to justify the Empire of Japan's seizure of Manchuria.

The five-member commission, headed by British politician Victor Bulwer-Lytton, announced its conclusions in October 1932. It stated that Japan was the aggressor, had wrongfully invaded Manchuria, and that it should be returned to the Chinese. It also argued that the Japanese puppet state of Manchukuo should not be recognized, and recommended Manchurian autonomy under Chinese sovereignty. The League of Nations General Assembly adopted the report, and Japan quit the League. The recommendations went into effect after Japan surrendered in 1945.
