After evading the issue for more than two years, Taro Aso conceded to foreign reporters on the eve of becoming prime minister that Allied POWs worked at his family's coal mine in Kyushu during World War II.

But Aso's terse admission fell far short of the apology overseas veterans' groups have demanded, while refocusing attention on Japan's unhealed legacy of wartime forced labor by Asians and Westerners.

Calls for forced labor reparations are growing louder due to Prime Minister Aso's personal ties to the brutal practice, as well as his combative reputation as a historical revisionist. The New York Times recently referred to "nostalgic fantasies about Japan's ugly past for which Mr. Aso has become well known." Reuters ran an article headlined "Japan's PM haunted by family's wartime past."
