Oumi-jima Island

Yamaguchi, Chugoku

An island also known as the "Sea Alps." A chain of bluffs and fantastically shaped rocks formed by sea erosion.

Oumi-jima Island is an island sitting in the Sea of Japan off the coast of Senzaki Bay in the north of Nagato in Yamaguchi. This island is about 40 kilometers around and linked to Senzaki by Oumi-jima Grand Bridge. The whole island is designated as a natural monument. It is also called the "Sea Alps," and is a representative place of scenic beauty in Kita-Nagato Coastal Quasi-National Park.

The northern coast of the island has many caves, bluffs, and queer looking rocks that were eroded by the sea. They include the sheer Juroku-Rakan rocks rising out of the sea that are said to look like sixteen 'rakan' (Buddhist monks who reached the top stage of Buddhist discipline), the Shimami-mon rock hole, the O-mon Rock, towering about 40 meters high, and many other caves and rocks of fantastic shapes. You can enjoy the view of these caves and rocks from an observation spot on the Oumi-jima Shizen-Kenkyu-ro (nature study path), a promenade overlooking the sea from Shizu-ga-ura, located nearly in the center of the island. If you want to take a closer look at the bluffs and fantastically shaped rocks from the sea and go inside the caves, an Oumi-jima sightseeing boat is available.

The Oumi-jima sightseeing boat tour takes about an hour and 30 minutes. Starting from Oumi-jima-ohashi Bridge, the boat takes you around to the various places to see and returns to Senzaki Port by way of the west and north seaside.
