There is tsukuridashi at the narrow part on the right and left. It is surrounded by triple moat around, whose present outer moat was dug again during the Meiji Period. The burial mound had stones and clay figures and yielded clay figures shaping a woman's head and horse. A Sueki earthenware pot was found in the east part of tsukuridashi during 1955 to 1964. A stone coffin placed in a pit-style stone room, sword, fine armor, glass pot and dish were excavated in the rectangular part of the mound in 1872.
