Culture and Science Museum for Children, Hiroshima-Shi

The Science Museum promises lots of hands-on activities for budding Einsteins and Hawkings, plus a nice introduction to Hiroshima's traditional cultural attractions. Parents will also appreciate it as a creative place for the average child to burn off some steam. Highlights include Japan's largest planetarium, which "dynamically reproduces glittering constellations and an infinitely expanding universe." Back on earth, a small library/reading room gives exhausted parents chairs to collapse in--and perhaps even take a nap while the kids explore.
