Mitsuru Tojo

In Tokyo, Osen is the servant girl of an unscrupulous antiques dealer, Kumazawa, who takes in the penniless Sokichi Hata. Kumazawa mistreats Sokichi and Osen, while swindling some Buddhist monks out of their temple treasures. When Kumazawa is arrested, Osen agrees to help Sokichi finance his dream of going to medical school. They live in a humble room, and eventually the only way Osen can find enough money for them is to prostitute herself during the day, without Sokichi knowing. (Will Gilbert)
