Prince Nagaya's designated tomb at Nashimoto, Heguri. Distinguishing the tradition-based designation from the underlying Kofun-period mound reveals the site's layered history.
Finds & research
Finds from the present grave are unknown; paving and a moat are known from the underlying Nashimoto-minami No. 2 mound.
Two views on the occupant
Archaeological view
The present round rise is about 15m across and 1.5m high and was designated in 1901. Beneath it lies the rear portion of the leveled early-6th-century keyhole mound Nashimoto-minami No. 2; the designated grave and underlying kofun are separate phases.
Imperial Household Agency view
Managed by the IHA (designated 1901) as the tomb of Prince Nagaya, Minister of the Left forced to death in the 729 plot. The ~15m knoll overlooks the Heguri valley; beneath it lies a leveled 6th-century keyhole mound, leaving the link to the 8th-century prince archaeologically uncertain.
Field notes
About 10 minutes on foot from Heguri Station; worship from the IHA oratory.
