Occupation of French Indochina

Japanese: 仏印進駐 - ふついんしんちゅう
Occupation of French Indochina

Japan's military occupation of French Indochina was carried out by agreement to pressure the Vichy government of France after the surrender to Germany. It was an important step in Japan's southward advance policy and was one of the causes of the Pacific War. (1) Occupation of Northern French Indochina. The Matsuoka-Henri Agreement was concluded on August 30, 1940 (Showa 15) under the pretext of blocking the route to aid Chiang Kai-shek, allowing Japanese troops to pass through, use airfields, and be stationed there. On September 23, 25,000 soldiers from the South China Expeditionary Army entered the area, but some troops ignored the promise of a peaceful occupation and forced their armed advance. (2) Occupation of Southern French Indochina. It began on July 28, 1941, with the aim of acquiring a base for the southern operation. France accepted Japan's request and agreed to the conclusion of the Japan-France Protocol (signed on the 29th of the same year), so the occupation was bloodless. However, this caused a severe deterioration in Japan-U.S. relations, and the United States took steps to freeze Japanese assets in the United States (July 25) and completely ban oil exports to Japan (August 1), with the United Kingdom and the Netherlands following suit.

日本が、対独降伏後のフランスのビシー政権を圧迫し、協定によって行った仏領インドシナの軍事占領。日本の南進政策の重要な一歩として太平洋戦争の原因の一つとなった。(1)北部仏印進駐。援蒋(えんしょう)ルート遮断の名目で1940年(昭和15)8月30日に日本軍隊の通過、飛行場使用、駐兵を認める松岡‐アンリ協定が締結された。9月23日から南支那(しな)派遣軍所属の2万5000の兵が進駐したが、その際一部部隊は平和進駐の約束を無視し武力進駐を強行した。(2)南部仏印進駐。南方作戦のための基地獲得のねらいで、1941年7月28日から行われた。フランスは日本の要求をのみ、日仏議定書(同29日調印)の締結に応じたので、無血進駐となった。しかし、これにより日米関係は極度に悪化し、アメリカは在米日本資産の凍結(7月25日)、対日石油輸出の全面禁止(8月1日)に踏み切り、イギリス、オランダもこれに倣った。
