Wartime History
During 1942, occupied by the Japanese when they occupied Biak. By early 1944, the Japanese developed this cave into a natural defensive fortress with soldiers and heavy weapons emplaced and hidden inside the cave.

On May 27, 1944, after the U.S. Army 41st Infantry Division made an amphibious landing at Bosnik. After the U.S. Army landing on Biak, Americans occupied portions of the cave while the rest was held by the Japanese and used to harass the landing force and bombard Mokmer Airfield (Mokmer Drome). To eliminate the threat, American forces began probing the cave system for entrances and weaknesses.

On July 7, 1944 during the early morning, the U.S. Army began attacking the cave and bombing and bombarding of the area. The attacks culminated with pumping drums of gasoline into cave entrances that was ignited. Inside, an estimated 3,000 Japanese were killed in the attacks.

The "Japanese Cave" (Goa Jepang) is located in a forest, the cave is one of the main tourist attractions on Biak. The entrance is surrounded by fences. According to Yusuf Rumaropen, an Irianese who has been taking care of the cave for decades years, the forest is kept intact; tree cutting is strictly forbidden to keep the historic site as it is.
