Sumo is a Japanese style of wrestling and Japan's national sport.
The basic rules of sumo are simple: The wrestler who either first touches the floor with something else than his sole or leaves the ring before his opponent, loses. The fights themselves usually last only a few seconds and in rare cases up to one minute or longer.
Right on the photography is Kaloyan Mahlyanov from Bulgaria. He has made a name for himself in Japan as Kotooshu.
Kaloyan is first European to win sumo wrestling's coveted Emperor's Cup.
