Tsudoshiroyama Kofun
The oldest giant keyhole-shaped kofun in the Furuichi Kofun Group.
Built in the late 4th century, Tsudoshiroyama Kofun is the oldest giant keyhole-shaped kofun (mounded tomb) in the Furuichi Kofun Group. The mound is 210 meters long and has a double moat and embankment. Waterfowl-shaped haniwa (clay figures) excavated from the inner moat have been designated as Important Cultural Properties of Japan. The surrounding area is a place where locals go to relax and enjoy seasonal flowers such as irises, cosmos, and plum blossoms.
