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.
