In Japan alone, over 160 POW slave labor camps existed at the time of surrender. Camps were located in many areas of mainland China including notorious camps in the Hong Kong and Shanghai areas. Prisoners were used mainly for mining coal, ore, ship building, airfield construction, and military defense bunkers. The most notorious were a camp in Palawan (massacre by fire of 150 Americans), Sandakan 2,200 British and Australians died in a forced march in Borneo), and a series of camps along the Burma-Thailand Death Railway (an estimated 15,000 Allied POWS perished, along with almost 180,000 civilians impressed into slavery).
During the Japanese occupation of the NEI, two large groups of people were deprived of their freedom: prisoners-of-war and detained civilians. These groups ended up in different camps. Both groups consisted of many more people than the Japanese had expected as well as the allies had expected at the liberation.
Around 8,200 of them lost their lives, about one out of every five. Besides, many native servicemen of the KNIL fell into the hands of the Japanese army. The Javanese and Sundanese were soon set free, but most of the Menadoese, Amboinese and Timorese, the Christian natives were held. Except on Borneo, most prisoners-of-war did not stay on the islands where they were captured, but were transported elsewhere, especially to be put to work.
The number of civilians interned by the Japanese is estimated to have been 125,000. The largest group concerned civilians from the Netherlands East Indies. Dutch scholars believe as many as 96,300 civilians ended up in Japanese camps or which 13,120 (13.6%) died. During the war the Japanese reported to the Red Cross that there were 98,000 detainees, of whom 16,800 died (17%). Though the precise figures are not known, we may assume that about 100,000 civilians from the Indies were in Japanese camps, of whom one in six died.
