I visited to Kanagawa Prefectural Museum of Cultural History with my son. It is located in Yokohama, near Bashamichi station. Its admission fee is 300 yen ($2.88 €2.11) for adults and free for junior high school student or under. It is an orthodox museum in which many historial things (from ancient era to modern society) are displayed.
