The Japanese Olympic Committee announced Friday that the representatives of all 31 Olympic sports federations it questioned over two days said no abuse exists within their organizations at the national level.

The questioning was the first step in an investigation by the JOC into physical and verbal abuse in Japanese sports. The investigation was prompted by a complaint from 15 women judo athletes that alleged physical and verbal abuse with the Japan national team.

The complaint has led to the resignations of the women's coach, an assistant coach and the All Japan Judo Federation's head of development.
