Overview

A 225m-long keyhole mound, the fifth largest in the Furuichi area. Built on a central plateau with its rear circle at the eastern edge and its front section facing west, it appears especially large when viewed from the lowlands to the east and south. The rear circle rises 20.7m; the mound has three tiers and projections on both sides of the waist. A broad embankment about 32m wide encircles the moat. The Imperial Household Agency administers the mound as a satellite of the Ojin mausoleum; the mound, its moat and part of the surrounding embankment are also included in the National Historic Site Furuichi Kofun Group. It is a constituent monument of the Mozu-Furuichi Kofun Group World Heritage Site, inscribed in 2019.

Finds & research

Records mention two burial facilities set north–south in the rear circle, the northern one said to contain a large chest-shaped sarcophagus. Cylindrical haniwa have been recovered along with figural pieces shaped as houses and quivers; a haniwa of a man holding a shield is among the earliest human figures of its kind. A moat rings the mound, with a broad embankment about 32m wide beyond it, and a ditch bounding that embankment has been detected on parts of the east and north sides.

Official status & archaeological view

Official status
Managed by the IHA as "Satellite Tomb No. Ho" of the Ojin Mausoleum, Ega-no-Mofushi-no-Oka-no-Misasagi (the preservation plan of the Fujiidera and Habikino boards of education lists it as "Ojin Mausoleum detached plot No. Ho"), and also one of the mounds of the National Historic Site "Furuichi Kofun Group". It is designated a satellite of Konda Gobyoyama Kofun (the Emperor Ojin mausoleum, 425m), although its 225m length makes it a large keyhole mound.
Attribution (jitei): the Imperial Household Agency's determination of whose tomb it manages — separate from heritage designation.
Archaeological view
It dates to the middle phase of the Middle Kofun period (early 5th century).

Field notes

Public access is restricted as an IHA mausoleum.
