The museum's 80,000-item collection features exceptional Jomon period pottery with elaborate cord-marked patterns dating back over 10,000 years, along with Yayoi period bronze bells and weapons. Particularly notable are ritual burial goods, including comma-shaped jade beads called magatama, and clay figurines called dogu. The museum also displays rare artifacts from ancient Mesopotamia and Egypt, including cuneiform tablets and mummy cases, which provide cross-cultural archaeological context.
