OSAKA, Japan (AFP) - A Japanese politician on Friday apologised to women forcibly drafted into military brothels during World War II after his comments about them being a military necessity sparked outrage.
Osaka mayor Toru Hashimoto issued the apology hours after he was due to meet two former "comfort women", but the elderly South Korean women cancelled over fears of becoming political pawns in a long-running row that has stoked tensions between Tokyo and Seoul.
"It is a shame that I couldn't meet them - I wanted to tell them I am sorry for this misunderstanding," mayor Hashimoto told a press conference.
"I hurt them with my words so it's natural that I want to apologise."
Earlier on Friday, supporters of the women, both in their eighties, said they were concerned Mr Hashimoto would not retract his controversial comments.
"He has to retract his past comments if he wants to apologise and make us believe it is genuine," supporter Pang Chung-Ja told a hastily arranged press briefing in Osaka.
She added there were fears the pair could be "politically exploited".
Earlier this month, the mayor said wartime sex slavery served a "necessary" role in keeping battle-stressed soldiers in line, setting off a volley of criticism from countries under Japan's rule in the 1930s and 1940s as well as from the US.
He later pledged to apologise for his comments, while insisting Japan's soldiers were not unique in brutalising women.
On Friday, Mr Hashimoto said his original remarks were misinterpreted.
"I happen to have used the word 'necessity' but it doesn't mean I personally meant it was necessary," he said.
"I mean that it is a historical truth that soldiers were using women. Was it not necessary for them?"
Sex slavery is a particularly sensitive issue in Korea, a former Japanese colony whose people made up many of the up to 200,000 "comfort women" forcibly drafted into brothels for the Japanese military during World War II.
In the days since his original comments, Mr Hashimoto, the co-leader of the national Japan Restoration Party, has continued to fan the flames with new pronouncements, many of which have been on Twitter where he has over one million followers.
Mr Hashimoto said in a comment reported on Tuesday that the South Korean military used women for sex during the Vietnam War, inviting a sharp response from Seoul.
"Japan was bad," he told a party meeting on Monday, the Asahi Shimbun newspaper reported. "It is true that we used women to solve the problem of sex on the battlefield.
"Having said that, America, Britain, Germany and France, and even the South Korean military in Vietnam after WWII, they all used women to address the issue."
Meanwhile, Tokyo on Thursday accused a South Korean newspaper of "dishonourable" behaviour for publishing an editorial that said the atomic bombings of Hiroshima and Nagasaki were "divine punishment" for Tokyo's wartime aggression.
The editorial in the Korean and English versions of the Joongang Ilbo daily on Monday said the 1945 nuclear bombs dropped by US planes, which together killed more than 200,000 people, were justified, saying: "God often borrows the hand of a human to punish the evil deeds of men."
