On Wednesday, July 22, 2026, Tokyo experienced its highest number of heat-related hospitalizations since 2010. Local authorities reported that 453 people were transported to hospitals across the prefecture due to the extreme heatwave affecting much of the Japanese archipelago. Tragically, one patient died, and four others were reported to be in critical condition.

The Tokyo Fire Department noted that their emergency response operations reached an unprecedented level not seen in at least 63 years. The department carried out 3,612 emergency interventions on Wednesday alone, marking a record high since 1963. In response to the crisis, officials have urged the public to stay hydrated and utilize air conditioning to mitigate the health risks associated with the ongoing rising temperatures.
