Wednesday was the first time in six years that the country recorded its first extremely hot day of the year in mid-June or later, according to the Japan Weather Association. Last year, the first such day was observed in Ibigawa, Gifu Prefecture, on 17 May. Mōshobi, or extremely hot days, are classified by the Meteorological Agency as days where the temperature rises above 35°C. Severe heat is forecast to continue Thursday and Friday, when temperatures are expected to rise to 30°C and above over a broad swath of the country, with 35°C and higher temperatures possible for some inland areas, and the WBGT forecast to rise to between 25°C and 28°C. Japan is highly likely to suffer another scorching summer this year after logging the hottest summer ever recorded in 2023, the Meteorological Agency said last month.
