One of southern Yamashiro's greatest early mounds, at the eastern foot of the Otokoyama hills in Yawata. The octagonal hall on its summit tells how the tomb later became a place of worship.
Finds & research
Five bronze mirrors, bracelet-shaped stones including 2 hoe-shaped and 10 wheel-shaped, and 27 sword fragments, among others (1902).
Official status & archaeological view
Official status
Part of the National Historic Site "Tsuzuki Kofun Group" (2022; expanded 2024).
Archaeological view
A keyhole mound ~120m long, the largest of the Tsuzuki group, built in the late 4th century (the latter part of the Early Kofun period, though its exact dating is debated). The pit-style stone chamber in its rear circle was struck and destroyed during construction work in 1902. Shoboji's octagonal hall, moved here from the Iwashimizu Hachimangu precinct in 1870, crowns the rear circle (the Amida statue formerly enshrined in it is an Important Cultural Property).
Field notes
View from the perimeter (the hall's interior can be visited by reservation); pairs with a visit to Iwashimizu Hachimangu.
