  • Dohyo

    dohyo

    T
    he sumo ring is called the dohyo and takes its name from the straw rice bag which mark out its different parts. The greater portion of each bale is firmly buried in the earth. The dohyo is 18 feet square and 2 feet high and is constructed of a special kind of clay. The hard surface is covered with a thin layer of sand. The bout is confined to an inner circle a little over 15 feet in diameter. Over the dohyo suspended from the ceiling by cables is a roof resembling a Shinto shrine with four giant tassels hanging from each corner to signify the seasons of the year.

    Rule

    Suspended roof A bout is won by forcing the opponent out of the inner circle or throwing him in the dohyo. To lose the match it is not necessary to fall in the circle or to be pushed completely out. The rikishi who touches the ground with any part of his body, his knee or even the tip of his finger or his top-knot, loses the match. Or he need only put one toe or his heel over the straw bales marking the circle. Striking with fists, hair pulling, eye gouging, choking and kicking in the stomach or chest are prohibited. It is also against the rules to sieze the part of the band covering the vital organs. As there are no weight limits as in boxing or western wrestling it is possible for a rikishi to find himself pitted against an opponent twice his own weight.



    Tournament

    Tournament T here are six Grand Tournaments a year, three are held in Tokyo, one in Osaka, Nagoya and Kyushu. A tournament lasts for fifteen days, each rikishi fighting once every day with a different opponent. The winner of the tournament, in other words the rikishi with the best record of wins over losses, is awarded the Emperor's Cup on the final day after the last match. There are three additional prizes, the shukunsho awarded to the rikishi who upset the most yokozuna(grand champions)and ozeki(champions), the kantosho for fighting spirit and the ginosho for technique. To be eligible for any of these prizes, the rikishi must also have won at least eight of his fifteen matches.
