The Honjo Kofun Cluster overlaps the town's central urban area; the town's management plan calls it "an extremely rare situation across Japan, with kofun lying within an urban area." In 1871, an officiant of Kentsuka Inari Shrine (宮永真琴) made the Honjo Kofun Map, and in 1874 he wrote an illustrated account too.
