Osaka mayor Hashimoto enflames 'comfort women' row
28 May 2013 Last updated at 00:59 BST
The mayor of Osaka has courted controversy for a second time by claiming that there is "no evidence" that the Japanese government forced tens of thousands of women into sexual enslavement during World War II.
Toru Hashimoto first drew international criticism when he said that the so-called "comfort women" were "necessary" for Japan's wartime troops. He has since described the practice as a violation of the women's human rights.
Mr Hashimoto has also accused the armies of the United States, Britain, France and Germany of similar actions during the conflict.
