After Japan's defeat in the Pacific War of World War II, a former Japanese military officer who had surrendered to the Allied forces and become a prisoner of war in a camp in Dutch-controlled Indonesia on August 15, 1945, committed seppuku in November 1945.

 　After Japan's defeat in the Pacific War of World War II, a former Japanese military officer who had surrendered to the Allied forces and become a prisoner of war in a camp in Dutch-controlled Indonesia on August 15, 1945, committed seppuku in November 1945. The Japanese military officer committed seppuku in grief and despair at the shame of Japan's surrender, and a large amount of blood flowed out of his abdomen. After committing seppuku, he lay face down and sobbed, holding his eyes. Seppuku was a form of ritual suicide in Japan, and was prescribed by Bushido. Seppuku was a more honorable form of suicide than falling into the hands of the enemy.

　 The devastating surprise attack on Pearl Harbor on December 7, 1941, also involved the Dutch East Indies in World War II, which continued until August 15, 1945. The Netherlands declared war on Japan on December 8, 1941. From early 1942, the Japanese army invaded North Celebes and North Borneo. In early February 1942, the attack on Sumatra began, leaving Java isolated. From March 1, 1942, the Japanese army began its attack on Java.On March 5th 1942, the Japanese army entered Batavia, and on March 6th they broke through to Bandung. On March 8th, they finally occupied Surabaya, and Java was in the hands of the Japanese army. On March 9th, the Dutch East Indies Army (KNIL) signed their surrender in Kalijati, near Bandung.

     On September 15th 1944, the Allied Forces landed on Morotai in the Moluccas. With the Allied Forces landing in the Dutch East Indies, the liberation of the Dutch and Indonesian people from the Japanese army became much closer. On May 1st 1945, the Allied Forces also landed in Tarakan and Balikpapan on the island of Borneo. Java, the largest island in Indonesia, remained occupied until the Japanese army surrendered on August 15th 1945. On September 2nd 1945, Japan officially signed the surrender documents on board the American battleship Missouri in Tokyo Bay.

     The treatment of Allied soldiers who became prisoners of war was based on Bushido, which treated them as inferior and shameful. Allied soldiers who became prisoners of war were routinely beaten, starved, abused, beheaded, forced to march, forced to work, tortured and massacred. Japanese soldiers justified their treatment of Western prisoners of war and residents by Bushido, which justified suicide rather than shameful surrender and falling into the hands of the enemy.
