A major central-Umami-group keyhole mound comparable in scale to Suyama Kofun.
Finds & research
The Imperial Household Agency holds comma-shaped, tubular, and jujube-shaped beads regarded as grave goods. The structure of the central burial facility and the occupant are unknown.
Two views on the occupant
Archaeological view
A 200m keyhole mound at Miyoshi, Koryo. Its rear is at least 120m across and 19m high, while the front is 118m wide and 17m high. It has projections, a moat, and an outer embankment. Cylindrical haniwa date it to the early part of the Middle Kofun period.
Imperial Household Agency view
The Imperial Household Agency manages it as the Miyoshi Mausoleum Reference Site. That status does not archaeologically establish a particular occupant.
Field notes
The precinct is closed as a Mausoleum Reference Site. View it from surrounding public roads and authorized worship areas.
