Sumo evolved over many centuries as a peripatetic form of public entertainment in which the wrestlers, trainers, and promoters depended on local gangs to secure facilities and an audience, including selling the tickets. This cozy relationship was supposedly dissolved when the traditional Sumo circle was modernized, becoming today’s JSA.
数个世纪以来，相扑都是一种四处流动表演的公众娱乐项目，因此相扑手，训练员和推广者都要依靠当地帮派来负责保卫场地和拉拢观众，甚至连卖票都一手包办。而这种暧昧的关系本该在相扑运动现代化，形成当今的相扑协会之后逐渐消亡。但除了日本广播协会电视频道支付了转播费用之外，相扑协会还有相当一笔财源是来自于门票收入。
