Sumo ring - Dohyo

Japanese: 土俵 - どひょう

A place where sumo matches are held. The dohyo appeared at the end of the 17th century. Before that, sumo did not have a dohyo. The first dohyo consisted of five bales of soil arranged in a square, which served as the boundary line, and the match was decided within this area. During the Genroku period (1688-1704), the dohyo were standardized to be circular, and the prototype of today's dohyo, which is set on top of a pile of earth, was created. After that, deciding techniques such as pushing the wrestler out of the ring or yorikiri were developed, and the sport became more interesting. The format has changed over the years, but currently, a square with sides of 545 cm (18 shaku) is piled with soil, and a dohyo (rice bale cut into thirds and filled with soil) is buried in the circle so that the inside diameter is 455 cm (15 shaku). In the past, four pillars (shihonbashira) were set up at the four corners of the ring, but since the autumn tournament in 1952, these have been replaced by tassels (fusa). →Ring-entering→Related topics Okinawa sumo｜Tekazu-iri

相撲の勝負を競う場所。土俵が出現するのは17世紀末。それ以前の相撲に土俵はなかった。最初の土俵は，土を入れた五斗俵を四角形に並べ，これを境界線として，この中で勝負を決めるようになった。元禄時代（1688年−1704年）になると円形の土俵に統一され，盛土の上に土俵を設けるこんにちの土俵の原型ができあがった。以後，土俵の外へ押し出したり寄り切ったりという決り手が生まれ，競技としての興味を増した。時代により形式は異なるが，現在は一辺545cm（18尺）の正方形に土を盛り，内径が455cm（15尺）になるように土俵(つちだわら)（米俵を３分して土を詰めたもの）を円形に埋め込む。かつては土俵の四隅に四本柱(しほんばしら)を設けたが，1952年秋場所以後，房(ふさ)に代わった。→土俵入り
