[1] In Japanese it is designated as a ryokuchi (緑地, green zone) instead of a park.
The park contains an archaeological site, the Shimoyakebe Site (下宅部遺跡) dating from the Jōmon period with the remnants of irrigation and waterworks from the Jōmon through Muromachi periods.
Numerous Sue ware pottery fragments have been found in the area.
This location is commemorated by a stone marker at the park's north eastern end.
It is famous for being an inspiration for parts of the anime film My Neighbor Totoro.
