The museum is popular for its circular, permanent exhibition rooms with no route, and the extensive exhibitions that are held 5 to 6 times a year. This is the only museum that handles the history of Yokohama from ancient times to ancient times. We also hold various events such as "Rekishi Kobo," a workshop for manufacturing, lectures and lectures. Adjacent to the museum, there is "Otsuka-Toshikatsudo Archaeological Park", where irregularities from the Yayoi period, such as pit dwellings, have been restored. Volunteer guides are available to explain archeological parks at any time. Please come to experience it!
