Manje od šest godina nakon svog debija u sumo hrvanju. bugarski hrvač Kotooshu postao je prvi Evropljanin koji je osvojio Veliki ljetni turnir u Tokiju i prigrabio Carski kup, najveću nagradu u tom drevnom sportu.
Less than six years after his debut in sumo wrestling, Bulgarian wrestler Kotooshu became the first European to win the Summer Grand Tournament in Tokyo and capture the Emperor's Cup, the biggest prize in the ancient sport.
