On April 17, 2007, Yoshiaki Yoshimi and Hirofumi Hayashi announced the discovery of seven official documents in the archives of the Tokyo Trials, suggesting that Imperial military forces – such as the "Tokkeitai" (Naval military police) – forced women whose fathers attacked the "Kenpeitai" (Army military police) to work in front-line brothels in China, Indochina, and Indonesia. These documents were initially made public at the war crimes trial. In one of these, a lieutenant is quoted as confessing to having organized a brothel and having used it himself. Another source refers to "Tokkeitai" members having arrested women on the streets and putting them in brothels after enforced medical examinations.
