Japan surrendered to the Allies on August 14, 1945. On August 29, Chiang Kai-shek appointed Chen Yi as Chief Executive of Taiwan Province, and announced the creation of the Office of the Chief Executive of Taiwan Province and Taiwan Garrison Command on September 1, with Chen Yi also as the commander of the latter body. After several days of preparation, an advance party moved into Taihoku on October 5, with more personnel from Shanghai and Chongqing arriving between October 5 and 24. By 1938 about 309,000 Japanese lived in Taiwan. Between the Japanese surrender of Taiwan in 1945 and April 25, 1946, the Republic of China forces repatriated 90% of the Japanese living in Taiwan to Japan.
