1Horizontal Well in Shukunegi

A horizontal well is simply a horizontally-cased well dug into the slope of a mountain. The terrain of Ogi Peninsula was formed by the eruptions of a submarine volcano. Thus, the rocks were soft enough to dig a horizontal well using manual labor.

2Iwayasan Cave

Iwayasan Cave is designated a Prefectural Cultural Property. The oldest earthenware on Sado was found within this cave, which was originally formed by wave erosion close to the shore. Later, as the island was lifted up from the seabed, the cave was moved to the height of about 70 meters, where it remains today.

4Shukunegi Coast

About 13 to 14 million years ago, the activity of underwater volcanoes was intense around Ogi Peninsula. Rocks and ashes from their eruptions accumulated and formed Shukunegi Coast. Later, the land uplifted and shaped the current terrain.
