Princess Ota's designated tomb on the approach to Empress Saimei's mausoleum at Kurumaki, Takatori. The designation matching the Nihon Shoki's location is kept distinct from the archaeological case for Koshitsuka-Gomon.
Finds & research
The designated tomb's burial facility and finds are unknown in the public record.
Two views on the occupant
Archaeological view
The IHA designates this as Princess Ota's tomb. Public evidence checked does not establish the designated site's archaeological form, size, date, burial facility, or finds. Koshitsuka-Gomon Kofun in Asuka is a strong alternative candidate, but it is a separate site.
Imperial Household Agency view
Managed by the IHA as the Ochi-no-Okanoe Tomb of Princess Ota — Emperor Tenji's daughter and mother of Prince Otsu — set partway up the stair to Empress Saimei's mausoleum (id:638), matching the Nihon Shoki's "tomb before the mausoleum." Scholars favor Koshitsuka-Gomon (id:664) as her true grave.
Field notes
Worship from the oratory on the IHA-managed approach.
