A beautiful stalactite can be seen in a cave made of limestone formations.
The area estimated to be used for dwellings in the cave is about 50 square emails, and the floor surface is uneven.
Earthenware from late Jomon period and late Jomon period were excavated, and animal bones were also found.
Traces of the furnace were found at the northern end.
The whole area is not clear because excavations have not been conducted, but it is a rare cave dwelling in the prefecture and is valuable.
