Activists wearing masks of Osaka mayor Toru Hashimoto (L-R), former Tokyo governor Shintaro Ishihara, Japan's Prime Minister Shinzo Abe and Japan's Finance Minister Taro Aso take part in a street drama during a protest in front of the Japan Interchange Association in Taipei, August 14, 2013. The Chinese characters on their bodies read, "prisoner." Protesters urged the Japanese government to formally acknowledge, apologize and accept its responsibility over comfort women, who were forced to become sex slaves for Japanese troops during World War II, according to local media.
