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
