Overview
The caves are usually located in the city town of Sekiya, and a branch of the Morikawa river flows around there.
This area is a limestone layer, the oldest being the Syrian sediments of 300 million years ago.
In the survey in 1968, the depth was measured to 93m, but it is unknown.
The stratigraphy has been confirmed up to 9 layers, and pottery is being excavated intermittently from the early Jomon period, from the shell bottom point pottery to the Yayoi pottery and pottery pottery.
Shellfishes are excavated such as giant clams, clams, clams, magaki, mussels, scallops and abalones, and animal bones are excavated as deer, wild boar, bear, fox and ten.
In the late Jomon period, human bones were found disturbed.
It is a representative of cave dwellings in the prefecture and is scientifically valuable.
