may face criminal charges of manslaughter.

"I think each stable master has his own opinion" about preventing hazing deaths, said Isenoumi, who is heading a committee aimed at stopping the problem. "We have come as far as making a first step."

Sumo stables have a long history of internal bullying as well as corporal and other violent forms of punishment, but traditionalists are being forced to re-examine their extreme methods in the wake of Saito's death.

The JSA said it will ask stable masters whether they take precautions to prevent discipline and acts of cruelty from going too far. Also being questioned are eating, sleeping and curfew times, as well as if wrestlers are ever bullied.

Stable masters are being asked to submit their responses to the JSA committee by Nov. 11, the first day of the Kyushu Grand Sumo Tournament.

The JSA committee in charge of preventing fatal hazing and other types of violence plans to visit individual stables from December based on the results of its findings.
