Korean women, like women in most newly industrializing countries, play multiple roles as workers, students, professionals, and housewives. The Korean constitution, which granted women's suffrage in 1948, advocates equal rights for women and men. Revelations in 1991 about atrocities committed against Korean women under Japanese colonial rule shocked the Korean people and stirred Japanese society as well. Koreans have continued to use the term "comfort women" when referring to the women in the sex industry that surrounds American military bases in Korea. According to Yun Chong-ok, who has been the driving force behind the emergence of the chongsindae issue in South Korea, not all women who served in the chongsindae were wi'anbu, or "comfort women." While most of the Korean men worked at the mines in Hokkaido, women from the southernmost part of the Korean peninsula were drawn to Osaka to work at spinning cotton in the textile mills there.
