A nostalgia bonanza from the Shōwa period, this museum concentrates on the years between 1955 and 1965, a time of great optimism between Japan's postwar malaise and its economic boom. You'll lose yourself among a delightful mishmash of movie posters, vintage cars, old toys, and household objects lovingly displayed in themed rooms. Even if you didn't live through this era, the warmth and detail of the collection is infectious and oddly moving.
