Tokyo reports its highest number of heat-related hospitalisations in more than a decade as a heatwave grips the city. Tokyo’s Fire Department says 453 people are taken to hospital on Wednesday for heat-related illnesses, the highest daily figure since records began in 2010. Other emergency-services data cited by multiple outlets also show emergency call-outs at their highest level since at least 1963, indicating a broader strain on emergency response during the extreme temperatures. One of the heat-related patients is reported to have died, according to Channel NewsAsia. The figures are presented as part of the city’s ongoing response to the heatwave, with emergency services handling a surge in cases linked to the hot weather. The combined reporting emphasises both the scale of hospital admissions and the elevated emergency call volume compared with historical baselines. The reports do not describe the specific causes of each case beyond heat-related illness, but they consistently frame the day’s numbers as the worst in Tokyo’s recorded history for the period covered.
