With the extended holiday approaching, Japanese residents are being warned to brace for rainy conditions to start off, followed by an intense heatwave. Weather forecasts indicate that most areas in Japan will experience considerable rainfall in the early part of the holiday before temperatures start to climb significantly to create a scorching condition. Authorities advise residents to take proper precautions against both severe weather conditions.

Weather news is crucial in Japan due to the country's diverse and at times, extreme climate conditions. People often plan their outings, travels, and various activities based on weather forecasts. The upcoming heatwave, escalates concerns, as Japan has seen severe heatwaves in recent years that have led to fatalities and serious health problems. There's also a societal value of preparedness, with advisories and warnings issued well in advance.

Much like in the U.S and EU, weather forecasts play a fundamental role in planning and preparedness in Japan. However, heatwaves in Japan can be more severe due to the higher humidity levels. In the U.S. and some parts of EU, authorities may issue heat advisories, encourage hydration, warn about leaving individuals in locked cars, etc. Such preventive measures are also prevalent in Japan.
