The largest keyhole mound in the Katsuragi region, famous for elaborate large house- and armour-shaped haniwa. Identification with Katsuragi no Sotsuhiko is unproven.
Finds & research
The looted southern chamber yielded mirror fragments, beads, and talc imitations. Large house-, pedestal-, shield-, and quiver-shaped haniwa stood on and around its roof stones. The northern chamber is unexcavated, though fragments of boat- and pedestal-shaped stoneware made in the Gaya region have been collected nearby.
Two views on the occupant
Archaeological view
A 238m, three-tiered keyhole mound at Muro, Gose, with stone facing, haniwa rows, and a northern square projection, dating to the early 5th century. Two burial facilities lie on the rear summit: the southern chamber contains a Tatsuyama-stone chest-shaped sarcophagus, while the northern chamber is unexcavated.
Imperial Household Agency view
This is not an Imperial Household Agency mausoleum. It was designated a National Historic Site in 1921 under the official name Miyayama Kofun.
Field notes
Follow the historic site’s public routes and do not damage exposed remains or the mound.
