Eten Island is located in Truk Lagoon in Chuuk State (Truk) in the Federated States of Micronesia. Also known as "Etten" or "Etan". To the north and northwest is Dublon Island (Tonoas, Tonowas) to the northwest is Truk Harbor, to the west is Fefan Island and to the south is Uman Island.

Wartime History
Occupied by the Japanese, military construction began in 1934 and began by leveling half the island for an airfield. After the expiration of the Washington Naval treaty in 1937, more construction began with help of the Japanese Navy and South Seas Government. In 1939 work intensified, with conscripted labor, Koreans, and Japanese prisoners also used. All construction was completed by late 1943.

Feature with an elevation of roughly 200' located at roughly the center of Eten Island. Also known as Mt. Uinku. During the Pacific War, the Japanese established defense on the hilltop.

Supporting these positions was a searchlight, command post, shrine, barracks, mess hall and generator building.
