History of the Archives:

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. A visit to the Archives provides a unique opportunity to know Yokohama's role as a junction of world and Japanese history.
In addition to permanent exhibitions, we hold special exhibitions four times a year in the Special Exhibition Room so that a visit is always an exciting experience.
Also, should you be looking for a particular book or document or have any questions about the history of Yokohama, please visit the Reading Room. Our dedicated staff will assist you with abundant documents and materials. Learning history gives you an idea of what the future holds.
