The Imashirozuka Kofun is widely identified as the tomb of the 26th Emperor of Japan, Keitai.
Archaeologists discovered a 'haniwa wall' at the site, which is considered a significant breakthrough in understanding 6th-century mortuary rites.
The museum grounds allow visitors to walk atop the actual kofun embankment, a rarity for major imperial tomb sites in Japan.
Some of the excavated haniwa figures are classified as Important Cultural Properties of Japan.
The burial site features a double-moat structure that has been partially restored to reflect its original landscape design.
Imashirozuka Ancient History Museum is located directly adjacent to the Imashirozuka Kofun, a designated national historic site and the 6th-century tomb of Emperor Keitai. The museum serves as an interpretive center for the burial mound, which is the only one among the Yodogawa River basin's royal tombs where visitors can walk within the burial area. The exhibition space features a life-sized reconstruction of the unique haniwa (terracotta clay figures) arrangement found at the site. Excavations revealed over 200 haniwa figures, including depictions of samurai, horses, and houses, which are displayed alongside detailed stratigraphic records. The museum integrates archaeological findings with the surrounding park environment to visualize the scale of the original tomb construction. It provides context for the Haniwa Festival, an annual event that celebrates the local history of the Takatsuki region.
