Kairiru Island

MapLat 3° 21' 0S Long 143° 34' 0E  Large island located off Wewak, next to Mushu 40km in circumference, its dominated by dormant volcano in the center.

The Japanese Navy garrisoned this island until the end of the war. The island was never invaded with ground forces, although it was attacked from the air by both the USAAF and RAAF.

The Navy garison was responsible for the exicution of many Allied aviators, including: 2nd Lt. Robert E. Thorpe and six American aviators. In 1945, two Australians were also exicuted, possibly there were other incidents as well.

The garrison was surrendered by Rear Admiral Sato to Australian Navy Major General Robertson in in September 10, 1945.  Three days later, the Army garrison surrendered at Cape Wom. The first repatriation of the Japanese from Kairiru occurred on December 26, 1945 when the Koei Maru took several hundred back to Japan.

St. Xaviar Mission / High School
Located halfway down the island, on the southern coast. Prior to the war, this was a mission. Today it is the island's high school. A Japanese Memorial is located at the school. Until at least 1969, the tail section of a Ki-43 Oscar remained near the school.

Kevin Fitzpatrick recalls:
"In 1969, there was a delegation from the Japanese Military, who came to Kairiru to exhume, and give a proper burial to Japanese soldiers who had died on the island during WWII. The sites where Japanese soldiers lay interred were remembered by the locals, and thus the remains were recovered."
