Edateku Island (Japanese: 枝手久島) is one of the islands of Amami Islands of Satsunan Islands, Japan. It administratively belongs to Uken Village, Ōshima District, Kagoshima Prefecture. It is a desert island far off the Amami Oshima coast.[1] It is said to be an origin of Achalinus werneri, a kind of colubrid snake species.[2]
The island was originally planned to be an oil reserve site in 1970s, but this plan was finally called off as it was strongly opposed by nearby villagers.[3]
