A lower house committee decided Thursday to hear from the government Friday afternoon about the results of a review on how the so-called Kono statement was composed.
The statement, issued in 1993 by then Chief Cabinet Secretary Yohei Kono, offered an apology to Asian women, euphemistically called "comfort women," who were forced to work in Japan's wartime military brothels.
The statement acknowledged for the first time the military's involvement in setting up "comfort stations" and the use of coercion in recruiting women to provide sex for Japanese soldiers before and during World War II.
Deputy Chief Cabinet Secretary Katsunobu Kato is scheduled to explain the review results in Friday's board meeting of the House of Representatives Budget Committee.
In February, Chief Cabinet Secretary Yoshihide Suga announced the government's plan to launch a team to "re-examine and understand the background" of the Kono statement.
The move drew criticism from the South Korean government, with its Foreign Ministry saying, "The more Japan denies its historical truth, the more it will be isolated from the international community."
But Japanese Prime Minister Shinzo Abe later denied that his government intends to change the statement itself.
The Kono statement says that the Japanese government extends "its sincere apologies and remorse to all those, irrespective of place of origin, who suffered immeasurable pain and incurable physical and psychological wounds as comfort women."
Japan set up the Asian Women's Fund in 1995 and earmarked 2 million yen in atonement money for each of the women, but some of them have rejected the money raised from private sector donations, instead seeking direct compensation from the Japanese government.
Tokyo maintains that all wartime compensation issues between Japan and South Korea have been settled under a 1965 bilateral treaty that normalized diplomatic ties between the two countries.
Japan ruled the Korean Peninsula as a colony from 1910 to 1945.
