One of the largest mounds in the Umami group and a Special National Historic Site. On the west side of the front is a two-tiered island-like installation linked to the mound by a causeway.
Finds & research
The island-like installation yielded lid-, house-, shield-, waterbird-, enclosure-, and fence-shaped haniwa. A wooden spade was found at the northwest corner of the front and a quiver-shaped wooden object at the northwest corner of the moat. The occupant is unknown.
Two views on the occupant
Archaeological view
A c.220m, three-tiered keyhole mound with a c.130m rear diameter at Miyoshi, Koryo. It has a moat, outer embankment, and projections on both sides. Built around the late 4th to early 5th century, it includes a two-tiered island-like installation linked by a causeway to the west side of the front.
Imperial Household Agency view
This is not an Imperial Household Agency mausoleum. It was designated a Special National Historic Site in 1952, and Koryo Town conducts conservation and continuing investigation.
Field notes
The moat also functions as an agricultural reservoir. Do not enter protected mound or embankment areas; follow Koryo Town’s access guidance.
