Sumo is a competitive contact sport where a wrestler (rikishi) attempts to force another wrestler out of a circular ring (dohyo) or to touch the ground with anything other than the soles of the feet. The sport originated in Japan, the only country where it is practiced professionally. :: Canon EOS 5D Mark II :: Schneider Componon-S 4.0/80mm / MFS :: http://photolog.blog.so-net.ne.jp/
