Why is there always so little surprise, but inevitably so much anger, when violence scandals break out in sumo?

The latest incident, in which Isegahama stablemaster (former yokozuna Terunofuji) self-reported using violence against top-division wrestler Hakunofuji, has sparked a reaction similar to that of every comparable incident over the past two decades.

Amid a wave of reproachful articles and reports, as well as emotionally charged fan responses online, few people appear to be surprised by the news ¡ª even though it involves someone whose personal reputation was overwhelmingly positive beforehand.
