What is Seodake Observatory?

The observatory is located on the west side of Odake, Kohama Island. Nearby is Kayama Island, and Iriomote Island and Yubu Island can be seen across the Yonara Channel.

It is not well known to tourists, so you can enjoy a private experience.

西大岳展望台からの展望

There is a "Monument of Churasan" and benches at the observatory, so you can take a break and go home.

There is a small parking lot where only a few cars can stop, and you can reach it by climbing about 100 steps that follow the slope from the entrance.

It may be difficult under the blazing sun in the middle of summer. Be sure to take precautions against heat stroke!
