慰安妇
During World War II, about 450,000 Korean male laborers were involuntarily sent to Japan. Comfort women, who served in Japanese military brothels as a form of sexual slavery, came from all over the Japanese empire. Historical estimates range from 10,000 to 200,000, including an unknown number of Koreans. However, 200,000 is considered to be a conservative number by modern historians, and up to 500,000 comfort women are estimated to be taken. These women faced an average of 29 men and up to 40 men per day, according to one surviving comfort woman. However, of the 500,000, less than 50 are alive . Comfort women were often recruited from rural locales with the promise of factory employment; business records, often from Korean subcontractees of Japanese companies, showed them falsely classified as nurses or secretaries. There is evidence that the Japanese government intentionally destroyed official records regarding comfort women.
