The Anpo protests, also known as the Anpo struggle (安保闘争, Anpo tōsō) in Japanese, were a series of massive protests in Japan from 1959 to 1960, and again in 1970, against the US-Japan Security Treaty, which is the treaty that allows the United States to maintain military bases on Japanese soil. The name of the protests comes from the Japanese term for "Security Treaty," which is Anzen Hoshō Jōyaku (安全保障条約), or just Anpo (安保) for short.
