Overview of Oshima Island

“Just like being on the moon”

Oshima Island is an island of Tokyo and is home to Mt. Mihara which occupies a large section of the central area of the island. It is an impressive active volcano responsible for many of the island’s hot springs and its jagged landscape. Ura-Sabaku, Japan's famous black desert, covers the side of Mt. Mihara and is claimed to resemble the landscape one can expect to see on the moon.
