Enoshima Island

Enoshima ( 江の島 ? ) is a small offshore island , about 4 km in circumference, at the mouth of the Katase River , which flows into the Sagami Bay of Kanagawa Prefecture , Japan . Administratively, Enoshima is part of the mainland city of Fujisawa , and is linked to the eponymous Katase section of that city by a 600-metre-long (2,000 ft) bridge. Home to some of the closest sandy beaches to Tokyo and Yokohama , the island and adjacent coastline are the hub of a local resort area .
