Sumo moves to beat Japan summer heat as temperatures rise

Sumo wrestlers have been performing throughout August in a demanding summer tour across various venues nationwide. In response to soaring temperatures and the increasing intensity of heatwaves, sumo authorities are implementing measures to counter Japan's scorching summer climate. The grueling annual tour, overseen by Takadagawa, who formerly wrestled and now serves as a stablemaster, may see changes aimed at enhancing the safety and comfort of the wrestlers.

Takadagawa has indicated that venues lacking air conditioning will no longer be accommodated for the summer performances, citing concerns over the physical strain on the wrestlers. Additionally, the tour schedule, which has traditionally spanned 90 days, is under consideration for reduction to approximately 70 days starting from next summer. The aim is to minimize excessive travel and physical exertion for the wrestlers by staging two- or three-day tournaments in closer locations.

Heat-related fatalities in Japan amount to roughly 1,300 incidents annually. Recently, Fijian rugby player Saimoni Vunilagi succumbed to severe heatstroke after being hospitalized with symptoms similar to heatstroke. Due to the rising temperatures, several cultural and sporting events have been rescheduled or adjusted in recent years to mitigate the impacts of extreme heat.
