Симодский трактат
During the Bakumatsu period, Shimoda was chosen by the Tokugawa government as a port to be opened to American trade under the conditions of the Convention of Kanagawa, negotiated by Commodore Matthew Perry and signed on March 31, 1854. Shimoda was also the site of Yoshida Shōin's unsuccessful attempt to board Perry's "Black Ships" in 1854. The first American Consulate in Japan was opened at the temple of Gyokusen-ji in Shimoda under Consul General Townsend Harris. Harris negotiated the Treaty of Amity and Commerce between the two countries, which was signed at nearby Ryōsen-ji in 1858. Japan's relations with Imperial Russia were also negotiated in Shimoda, and in 1855 the Treaty of Shimoda was signed at Chōraku-ji.
