Japan logged its fifth consecutive “cruelly hot day” on Saturday, extending a run of extreme heat that local media said is the longest since this record category began in 2010. The term was introduced this year as a way to warn the public when temperatures climb above 40C.
The latest reading underscores how severe the current hot spell has become. Officials also issued heatstroke warnings as the dangerous temperatures continued, highlighting the health risks linked to prolonged exposure to this level of heat.
Japanese media described the streak as unprecedented in the records kept under this specific heat measure. The label “cruelly hot day” reflects an effort by meteorological authorities to communicate that the conditions go beyond ordinary summer heat.
With the extreme temperatures showing little immediate relief, attention has remained on public safety and the impact of sustained heat across Japan. The five-day stretch has added to concerns about how often the country may face this kind of intense weather.
