Moreover, depending on Sunday's outcome of the New Year Grand Sumo Tournament tournament in Tokyo, he is likely to be joined at the top of the sport's tree by ozeki (champion) Asashoryu. Since he is Mongolian, it means that the top flight of the national sport will, for the first time, exclusively comprise foreign-born athletes.
