A square-type mound on a hill in Nishikori, Otsu, overlooking Lake Biwa and the Hiei range. Its stone cladding, angled to gleam toward the lake, makes vivid the kofun's role as a monument built to be seen. Maintained as a kofun park, it doubles as an easy lookout from the city.
Finds & research
Full stone cladding, five burials (presumed clay-encased), and pottery. No notable grave goods are known.
Two views on the occupant
Archaeological view
A square-fronted, square-backed mound ~60m long (No.1; rear width ~35m), built in the late 4th century as the oldest chieftain's tomb in the Otsu area. Its slopes are fully stone-clad, with the lake-facing east side finished most carefully — clearly meant to be seen from the water. Five burials (four in the rear, one in front, presumed clay-encased) are known. Round mound No.2 (~20m, late 3rd century) adjoins to the north. A link to the Wani clan has been suggested.
Imperial Household Agency view
Not designated by the IHA. National Historic Site (designated 1974).
Field notes
Walkable from Omi-Jingu-mae Station (Keihan). Maintained and open as a kofun park (developed 1981–85). Combines well with Omi Shrine and the Otsu Palace site.
