In March, 1930, positions of ringside sumo judges, who were sitting on the dohyo until that time, were moved to places below the dohyo because their presence on the dohyo might not only block sight lines of the audience but also become a cause for injury of sumo wrestlers, and the number of judges was increased to five and the Shiooke (salt pails) were tied to the hoya posts.
