In early spring, the plum blossoms are beautiful, in early summer there is the new greenery, and in autumn the foliage paints the area in vivid colors. The building will become a center of outdoor activity in this environment and will no doubt function as the nucleus of the region. The roof is a stepped plaza and will be used for drama and music festivals, various performances, and lectures. Once inside the building, the darkness spreads. The unearthed objects are exhibited in the same way that they were found in the tumuli.
People experience the sensation of entering a kofun.
A visit to the building represents a journey to the under-world of ancient times. This is a place where the Japanese encounter their own history. It is also a tumulus built in the Heisei era and dedicated to the Japanese love of nature. Exhibition Room 4. Museum Library, Information Service Desk 5.
