A round mound built against the outer moat on the north side of Konda Gobyoyama Kofun, the mausoleum of Emperor Ojin. It is 50m across and 7m high and was built in two tiers. From its position it is thought to be related to the great mound, and the Imperial Household Agency administers it as a satellite tomb. It is dated to the middle phase of the Middle Kofun period. In the Mozu-Furuichi Kofun Group World Heritage Site, inscribed in 2019, it forms a single constituent property with the Ojin mausoleum and Futatsuzuka Kofun.
Finds & research
Cylindrical haniwa like those of the Ojin mausoleum and figural haniwa have been recovered from the mound. Gilt-bronze horse gear traditionally said to have been found here in 1848 is held by Konda Hachimangu Shrine. The saddle fittings and related objects are National Treasures, thought to have reached Japan from north-eastern China or the Korean Peninsula, and are among the oldest horse gear known in Japan.

Attribution (jitei): the Imperial Household Agency's determination of whose tomb it manages — separate from heritage designation.
Archaeological view
The Furuichi Kofun Group preservation and utilization plan of Fujiidera and Habikino cities lists it as a satellite tomb within the Ojin mausoleum precinct. The Agency for Cultural Affairs dates it to the middle phase of the Middle Kofun period, while the official World Heritage website and Habikino City give the first half of the 5th century. The National Treasure horse trappings are traditionally said to have been found in this mound in 1848. The Agency for Cultural Affairs considers, from its position, that it is a mound connected with the Ojin mausoleum.
Field notes
The official World Heritage site gives about a 15-minute walk southwest from Kintetsu Hajinosato Station (Minami-Osaka Line). The mound is managed by the IHA and cannot be entered; view it from the surrounding streets.
