日本气象厅25日发布报告称，日本从21日至25日连续5天观测到40摄氏度及以上高温，创下有可比数据以来的最长连续纪录[1]。其中，岐阜县美浓市和多治见市分别录得40.8摄氏度和40.7摄氏度的高温，三重县桑名市也观测到40.6摄氏度[1]。这是2010年以来首次出现连续5天40摄氏度以上的高温天气，此前最长的连续纪录为4天，曾在2013年8月10日至13日和2025年7月30日至8月2日出现过两次[1]。
极端高温给民众生命安全造成严重威胁。东京都22日一天内超过450人因中暑被紧急送医，创下开始相关统计以来的单日最高纪录[1]。7月13日至19日一周内，全国共有10857人因中暑被紧急送医[1]。
Japan's Meteorological Agency reported on July 25 that the nation had experienced its longest consecutive period of temperatures at or exceeding 40 degrees Celsius, spanning five days from July 21 to 25[1]. This streak surpassed all comparable historical records in the country's weather data[1].
Multiple regions across Japan recorded dangerous highs during this period[1]. Mino in Gifu Prefecture reached 40.8 degrees Celsius, while Tajimi in the same prefecture measured 40.7 degrees Celsius and Kuwana in Mie Prefecture recorded 40.6 degrees Celsius[1]. The extreme conditions placed severe strain on Tokyo's emergency services, with over 450 people requiring hospitalization for heat-related illness on July 22 alone—marking the highest single-day total since such statistics began being tracked[1]. During the week of July 13 to 19, a total of 10,857 people were rushed to medical facilities due to heat-related ailments[1].
Prior to this event, Japan had twice experienced consecutive four-day periods of temperatures exceeding 40 degrees Celsius—occurring from August 10 to 13, 2013, and July 30 to August 2, 2025[1]. The current five-day streak represents the first time since 2010 that such a prolonged consecutive extreme heat event has been observed[1].
