Treaty of Mutual Cooperation and Security Between the United States and Japan

The Treaty of Mutual Cooperation and Security between the United States and Japan (日本国とアメリカ合衆国との間の相互協力及び安全保障条約, Nihon-koku to Amerika-gasshūkoku to no Aida no Sōgo Kyōryoku oyobi Anzen Hoshō Jōyaku), also known in Japan as Anpo/Ampo jōyaku (安保条約) or just Anpo/Ampo (安保) for short, is a treaty that permits the presence of U.S. military bases on Japanese soil, and commits the two nations to defend each other if one or the other is attacked. Over time, it has had the effect of establishing a military alliance between the United States and Japan. The current treaty, which took effect on June 19, 1960, revised and replaced an earlier version of the treaty, which had been signed in 1951 in conjunction with the signing of the Treaty of San Francisco that ended World War II in Asia.
