Troubled yokozuna Asashoryu could leave for Mongolia to undergo treatment for a mental disorder as early as next Wednesday, sumo sources said Saturday. According to the sources, the Japan Sumo Association is to hold an executive committee meeting in order to rubber-stamp the grand champion’s return to his homeland sometime between Sunday and the day before he leaves. “What has been decided by the executive committee will be reviewed one more time by the committee,” said JSA Chairman Kitanoumi. “Asashoryu is a yokozuna but first and foremost he is a human being. We will monitor his situation a little bit longer but if it (his condition) gets any worse then it becomes the responsibility of the sumo association.” “We will respect the doctor’s opinion and leave the verdict up to him,” said Kitanoumi.
