Two views on the occupant

Archaeological view
A 5th-century round mound about 30m across with three pit-style stone chambers. Himeji City gives its height as about 2m, while the Agency for Cultural Affairs gives about 4m. City sources also disagree on the date: a 2026 city bulletin says the first half of the 5th century, while the city school and tourism guides say the latter half. The first chamber was looted; the second and third yielded mirrors, gold earrings, swords, armor, and beads.
Imperial Household Agency view
Not designated by the IHA. Hyogo Prefectural Historic Site (1973); the finds were designated Important Cultural Properties in 1998.

Field notes

About one minute on foot south of the Himeji Archaeology Center. Admission is free; it closes Mondays and on some other days. The center holds the finds, but they are not necessarily on permanent display, so check current exhibitions.
