The Imperial Japanese Army asked the government to provide one “comfort woman” for every 70 soldiers, Japan’s Kyodo news agency said, citing wartime government documents it had reviewed, shedding fresh light on Tokyo’s involvement in the practice.
“Comfort women” is a euphemism for the girls and women - many of them Korean - forced into prostitution at Japanese military brothels. The issue has plagued Japan’s ties with South Korea for decades.
Later, there were also several “comfort women” reported from the Philippines during the second world war.
One dispatch from the consul general of Qingdao in China’s Shandong province to the foreign ministry in Tokyo, says that the Imperial Army asked for one woman to accommodate every 70 soldiers, Kyodo reported late on Friday.
Another dispatch, from the consul general of Jinan, also in Shandong province, notes “at least 500 comfort women must be concentrated here” as the Japanese forces made further advances, Kyodo said.
The 1993 “Kono Statement”, named after then-Chief Cabinet Secretary Yohei Kono in whose name it was issued, acknowledged Japanese authorities’ involvement in coercing the women to work in the brothels.
No officials were immediately available for comment at Japan’s Cabinet Secretariat, which Kyodo said collects official documents concerning comfort women.
South Korea reached a settlement with Japan to resolve the comfort women dispute in 2015, in which Japan apologised to victims and provided 1 billion yen ($9m) to a fund to help them.
Relations between the two East Asia neighbours have deteriorated since South Korea’s top court ruled in favour of South Koreans seeking compensation from Japanese firms for wartime forced labour.
