Caves are not infrequently found in the Paleozoic and Mesozoic limestones which are distributed near the Sakawa Basin.
The age of formation of these caves are considered to be correlated with those of the middle and upper erosion surfaces and lower terrace surrounding this basin.
In these caves yellowish or reddish brown clayer residuals intermingled with limestone gravels are deposited and some fossil bones of several kinds of animals are found frequently.
Some artifacts are also excavated from the upper part of these deposits. However, the relation between the layer of the artifacts and the “Onji” which is deposited at the upper part of the terrace could not be traced.
Some artifacts of the early Jomon period including tongued points were excavated from the Hijiritaki cave (Fudo-no-iwaya) (+150m) situated at Nishiyama, Sakawa-chô, on Feb. 1964.
These artifacts are the oldest remains from Kochi Pref. and correlated to those of Kamikuroiwa in Ehime Pref. This fact suggests that cultural exchange might have occurred between the Seto Inland Sea region and Tosa, the Pacific coast of Shikoku, at that preiod.
