Japan has cut funding to its judo federation after an investigation into the alleged physical abuse of female athletes found evidence of serious misconduct by coaches.

The Japanese Olympic Committee (JOC) said in a statement on Tuesday that it had issued 13 directives to the All Japan Judo Federation (AJJF) after the probe carried out by executive board members and a third-party lawyer.

Fifteen current and former members of the women's team had sent a joint letter of complaint to the Japanese Olympic Committee alleging harassment and violence by head coach Ryuji Sonoda and his staff in the buildup to last year's London Olympic Games.

The athletes said they had been slapped, shoved and beaten with bamboo.

Sonoda announced his resignation in January after the country's sports minister called for a fresh inquiry into the allegations.

"After a thorough review, the committee concluded that serious misconduct had occurred," JOC said in the statement.

"The directives include prohibition of violence or misconduct directed at athletes by coaches, the establishment of a framework for athletes to communicate concerns to the organization's decision-makers, clear and transparent procedures for selection of national team members, and the increased hiring of women as coaches and AJJF executives.

"The Executive Board also decided to cut the AJJF's annual subsidy for team development in the fiscal year starting next month."

The JOC said it had set up a system for the anonymous reporting of any violence, harassment or misconduct in sports administered by Japan's national federations.

Japan is the birthplace of the martial art but the team suffered one of their worst judo medal hauls in London with only one gold after being tipped to take home at last seven.

With Tokyo shortlisted against Istanbul and Madrid to host the 2020 Olympic Games, the Japanese bid team are keen to avoid any negative publicity ahead of September's vote in Buenos Aires, Argentina.
