関東と東海「酷暑日」予想 熱中症に厳重警戒 東北では激しい雨 — 2026-07-21

Tokyo, distilled to impact.
## Short Segments In a recent development, Japan's Cabinet Office has issued a notification to prefectures across the country, advising them to narrow down evacuation areas in the event of a tsunami warning. This comes after a major earthquake near the Philippines in June prompted widespread tsunami alerts, leading some municipalities to issue evacuation orders for areas expected to be inundated by the largest class of tsunamis. The Cabinet Office warns that issuing broad evacuation orders could burden the elderly and undermine trust in evacuation information. This move aims to ensure more targeted and effective evacuation strategies, enhancing public safety and trust in emergency communications. Today marks the beginning of deliberations in Japan's House of Councillors on the "Secondary Capital" bill, a legislative proposal aimed at preparing for large-scale disasters. The bill, backed by the ruling Liberal Democratic Party and the Japan Innovation Party, faces criticism from opposition parties who argue that the criteria for designation are biased towards Osaka. The ruling parties are pushing for understanding, emphasizing the bill's importance for disaster preparedness. As the debate intensifies, the outcome could significantly impact Japan's disaster management strategies and regional development plans. ## Feature Story Japan is bracing for an unprecedented heatwave, with temperatures expected to soar above 40 degrees Celsius in parts of the Kanto and Tokai regions. This marks the first occurrence of such extreme heat, termed "scorching days," this year. The Japan Meteorological Agency has issued heatstroke alerts for 43 regions, the highest number this year, urging residents and tourists alike to take maximum precautions. The intense heat is attributed to a strengthening Pacific high-pressure system, which has also led to the official end of the rainy season in these areas. As temperatures rise, the risk of heat-related illnesses increases, with reports already indicating multiple fatalities and numerous hospitalizations due to suspected heatstroke. The situation is compounded by unstable atmospheric conditions, which could lead to sudden weather changes, including thunderstorms, particularly in mountainous areas. Authorities are advising people to stay hydrated, avoid outdoor activities during peak heat hours, and remain vigilant for any sudden weather changes. This heatwave highlights the growing challenges posed by climate change, as Japan experiences more frequent and intense weather extremes. The government and local municipalities are on high alert, coordinating efforts to provide relief and ensure public safety. As the heatwave continues, the focus remains on minimizing health risks and maintaining public awareness. The coming days will test the resilience of infrastructure and emergency services, as well as the public's ability to adapt to these extreme conditions. The situation underscores the importance of preparedness and the need for ongoing adaptation strategies to cope with the impacts of climate change.
