During the Battle of Iwo Jima, the bodies of Japanese soldiers killed by American flamethrowers and bombs were scattered around an underground bunker. The bunker was later used as an American crematorium.

    At the Battle of Iwo Jima at the end of the Pacific War of World War II, the bodies of Japanese soldiers killed by American flame throwers and bombs in the underground caves were scattered around. The underground caves were later used as an American military crematorium. The underground caves were connected by a series of cave-like underground passageways. Most of the Japanese soldiers died in these tunnels.

   The bodies scattered around Iwo Jima were killed by the greatest fury. A large group of bodies were mutilated and cut into pieces. Many bodies were cut in half and scattered far away. In some areas, the stench of burning Japanese soldiers' bodies was very strong.

    In the Battle of Iwo Jima, the number of casualties among the attacking American forces exceeded that of the defending Japanese forces. Approximately 7,000 American soldiers were killed in action, and the number of wounded reached approximately 19,000.

    From February 19th to March 26th 1945, a bloody battle raged between the Japanese and American forces on the small Pacific island of Iwo Jima. 20,933 Japanese soldiers barricaded themselves in Iwo Jima in an attempt to defend it at all costs. The American forces that were to attack the island had 800 ships, 4000 aircraft and a total of 250,000 troops, and the landing operation began. The Japanese army had already lost Saipan eight months earlier on July 9th 1944, and on October 20th 1944, they landed on Leyte Island, and the organized resistance of the Japanese army had collapsed.
