The Yokohama Archives of History were established on June 2, 1981, at the historic site where Japan and the U.S. signed the Treaty of Kanagawa in 1854. The purposes of the Archives are to preserve and exhibit to the public historical materials from the Edo period to the Taisho-Showa era, and to facilitate understanding across generations and interaction among citizens.
