Mongolian grand champion Asashoryu, known for his truculent and fiery nature, said Thursday he has decided to bring an end to his illustrious but trouble-laden career.
Asashoryu, 29, was accused recently of seriously injuring a man in a drunken rampage.
The yokozuna and his stable master, Takasago, were summoned by the Japan Sumo Association board of directors for questioning about the incident. Asashoryu turned in his resignation, which was accepted by the governing board.
