An unusual feature of this kofun is the presence of a rectangular mound on the far end of its anterior portion, which may have been a ceremonial platform.

During the Sengoku period, the tumulus was fortified as a castle by the forces of Toyotomi Hideyoshi during the 1584 Battle of Komaki and Nagakute.

[2] The site is now open to the public with the exterior of the tumulus restored to its appearance at the time of construction, with a row of replica pot-shaped haniwa as part of the Aozuka Kofun Historical Park, which also has an on-site museum.
