Chief Cabinet Secretary Yoshihide Suga on Monday denied a media report that Seoul has demanded Prime Minister Shinzo Abe apologize over the "comfort women" issue during the upcoming summit between Abe and South Korean President Park Geun-hye.

"I haven't received any report. There is no fact like that, either," Suga told a regularly scheduled news conference.

"Comfort women" refers to girls and women who were forced to provide sex for Japanese troops before and during World War II.
