土俵，是日本相扑比实时的圆形擂台，直径4.55m，高34至60cm，并以米袋围起来，土俵上面覆盖沙子，并建造在面积6.7米的方形平台上。

在该俵中心有两条白色的线，力士就是在这里准备比赛。

土俵上方有一个类似神社屋顶吊在半空的建筑，称神明造，四角悬挂黑、青、红、白，象征四神。

The dohyō (土俵) is the ring in which sumo wrestling bouts are held. A modern dohyō is a circle of rice-straw bales 4.55 meters in diameter, mounted on a square platform of clay 6.7m on a side, and 34 to 60 cm high. The surface is covered by sand.
