TOKYO, July 22 (Reuters) - Japan sizzled under sweltering, life-threatening heat on Wednesday, with temperatures expected ‌to top 40 degrees Celsius (104 degrees Fahrenheit) ‌in some cities in what the government has newly designated ​as a "brutally hot day."

The weather agency issued heat stroke alerts for much of the country, forecasting a second straight day of "kokushobi" - literally meaning brutally hot ‌day - with temperatures ⁠expected to reach 40 C in Kumagaya, north of Tokyo, and Nagoya, in ⁠central Japan.

Authorities urged residents to use air conditioning liberally, hydrate regularly and avoid spending long hours outdoors.

Japan ​has experienced ​increasingly severe summers ​in recent years, with ‌the country recording its all-time high temperature of 41.8 C last year.

Even before this week's extreme heat, 4,580 people were taken to hospital between July 6 and 12, including seven who later died, ‌according to the latest data ​available from the Fire and ​Disaster Management Agency.

The ​weather agency this year introduced the "kokushobi" ‌category for days when temperatures ​reach 40 ​C or higher, reflecting the growing frequency of extreme heat. More than 100,000 people were ​taken to ‌hospital for heatstroke during the 2025 summer season, ​according to government data.
