Lat (DMS) 5° 43' 60S Long (DMS) 148° 21' 11E Aisega is located on the western coast of West New Britain. Wartime spelling "Aisega". Also known as Aisago, Aishiga or Aisiga.
After the U. S. Marine Corps landing at Cape Glouchester on December 26, 1943, the Japanese Army 51st Reconnaissance Regiment sailed from Rooke Island to Aisega, then marched northward to an assembly area at Nakarop before launching attacks against the Americans.
After December 27, 1943 only a token force remained at Aisega including a reinforced rifle platoon manning the defenses once occupied by a battalion and some service troops. A week later by early January 1944 this platoon departed when ordered to join the main Japanese force attacking the American landing area.
