A terminal-period tomb whose polychrome murals were discovered in 1972. The painted stones were removed with the dismantled chamber in 2007, conserved through fiscal 2019, and remain under Agency for Cultural Affairs management. The mound interior is closed; copies and a chamber model can be viewed at the Takamatsuzuka Mural Hall.
Finds & research
Finds include lacquered-coffin fragments, coffin fittings, copper nails, sword fittings, a sea-beast-and-grapevine mirror, and glass and amber beads. Murals survive on the east, west, and north walls and ceiling; no Vermilion Bird has been confirmed on the south wall.
Two views on the occupant
Archaeological view
A two-tiered round mound, 23m across at the lower tier, 18m at the upper tier, and 5m high. A 2005 investigation dated it to the Fujiwara-kyo period (694–710). The dressed-tuff chamber bears the Blue Dragon on the east, White Tiger on the west, Black Tortoise on the north, sun and moon, male and female groups, and a ceiling star chart. No Vermilion Bird survives on the south wall, which was breached by looters.
Imperial Household Agency view
This is not an IHA mausoleum. The mound became a National Special Historic Site in 1973; the murals were designated National Treasures and the finds Important Cultural Properties in 1974. It is a component of the World Heritage property Ancient Capitals of Asuka and Fujiwara, inscribed in 2026.
