Biak Island, off Papua's north coast
Gua Binsari or “Gua Jepang” or Japanese cave, 5 kilometres from Kota Biak, where thousands of Japanese soldiers hid until 26 June 1945; when they refused to come out after allied troops pinned them down, drums of petrol were thrown in and set ablaze with bombs; they were all killed.
