Judo: Japan coach quits over physical abuse scandal

TOKYO (AP) - Japan's women's judo coach Ryuji Sonoda has resigned over accusations he physically abused female judoka at a training camp before the London Olympics.

Sonoda said at a press conference on Thursday it would be "difficult" for him to continue with his job in light of the accusations.

Japan's judo confederation confirmed on Wednesday that Sonoda used violence after it was revealed that 15 female judoka sent a letter to the Japanese Olympic Committee at the end of 2012 complaining they had been subjected to harassment and physical violence by Sonoda in preparations for the Olympics.

"I deeply regret that my behavior, words and actions have caused trouble," said Sonoda, a former world gold medallist in the men's 60kg category. "It will be difficult for me to go any further with the training of the team."
