Oyu Stone Circle

Part of the ruins

The Oyu Stone Circle (大湯環状列石; kanjoseki) is a complex of ruins from the Jomon Era in the Towada area of Kazuno. It has been designated by the national government as one of the special artifacts of Japan.


This is a large ruin from the first half of the late Jomon period. Situated on the left bank of the Oyu River, a tributary of the Yoneshiro River, it is an important ruin which shows the thought process of the Jomon people. Both the Manza and Nakado circle are roughly 45 meters in diameter, and are thought to have been built over a period of more than 200 years.
