Inarizuka Kofun is a Tokyo-designated historic site, estimated to date from the early 7th century. Surveys around it found a ditch and judged it a round mound about 34 m across, but it may also be an octagonal mound, a form with few known examples nationwide. Its stone chamber has been backfilled for protection.

The larger tree is 25 m tall with a trunk girth of 5.9 m, and together their crown spans about 28 m. Tokyo describes it as a large tree from a wealthy farmer's garden that keeps the look of the Tama Hills.

The remains of the south wooden-gate fence at Kasuminoseki are a Tokyo-designated historic site, the site of a barrier fence said to have been set up on the Kamakura-kaido road in 1213 (Kenreki 3). Round-pillar marks found beside the Kumano Shrine approach, 16 at 45 cm intervals, are thought to be the barrier's southern gate fence.
