Teary-eyed and his voice shaking, pop star Tatsuya Yamaguchi apologized Thursday for kissing and engaging in indecent behavior with a high school-aged girl in a career-crushing scandal leading to his indefinite suspension from show business.

"I will spend my days taking a hard look at myself and praying that the victim, her family and her friend can someday be at peace and return to their lives before this took place," said Yamaguchi, the bassist for the popular all-male idol group Tokio, during a hastily arranged news conference at a hotel in Tokyo.

News broke Wednesday that Yamaguchi, 46, had been referred to prosecutors for allegedly kissing the girl against her will at his home in Minato Ward, Tokyo, in February.
