Yaene is a beach-entry site in a calm bay on the west coast of Hachijojima, sheltered, with less wave and surge. It is the island's most-used dive point, a shallow dive over sand and rock that suits divers of every level. Turtles often turn up right after entry, and nudibranchs supply the macro life.

Also known as 八重根.

The dive

Divers walk in from the beach into the calm water of the bay. The bottom starts out sandy at 6-7 m, then concrete boulders, which fill with lobsters at night, and rock gardens appear as the depth reaches about 12 m. A right turn at the boulders leads to a rock covered in large anemones crowded with young clownfish, and further on divers can spend time at 7-8 m watching the turtles. About 200 m out, a 12 m-deep arch shelters turtles and rock lobsters. Green turtles are common, and nudibranchs add the small life.
