This museum houses the private collection of the messianic religious leader Mokichi Okada (1882–1955), who founded a movement called the Sekai Kyusei Kyo (Religion for the Salvation of the World). He also acquired more than 3,000 works of art; some are from the Asuka period (6th and 7th centuries). Among these works are several particularly fine ukiyo-e (Edo-era wood-block prints) and ceramics. On a hill above the station and set in a garden full of old plum trees
and azaleas, the museum also affords a sweeping view over Atami and the bay.
