Weather Divide: Rain and Chill in the North
Low pressure and frontal systems are influencing weather patterns from Hokkaido to Hokuriku this morning. Commuters in cities such as Sapporo, Niigata, and Kanazawa should exercise caution regarding slippery roads and reduced visibility. Although the rain is expected to taper off as high pressure moves in, wet surfaces will remain a hazard for both drivers and pedestrians throughout the day.
residents in the north will experience a notable cooling trend. Temperatures are expected to be 5℃ to 10℃ lower than those recorded on Thursday. With wind speeds likely to increase, the air will feel particularly chilly, and residents in areas like Sapporo and旭川 (Asahikawa) are advised to wear jackets and choose wind-resistant clothing to manage their body temperature.
Heat and Humidity in the South

Forecasts indicate highs of 32℃ in Tokyo, 30℃ in Nagoya, 33℃ in Kochi, and 30℃ in Kagoshima. Officials urge the public to prioritize heatstroke prevention by staying hydrated, taking regular breaks, and utilizing hats or parasols when outdoors.
The afternoon may bring sudden showers to the Kanto and Tokai regions, making it a wise precaution to carry a folding umbrella. Meanwhile, Okinawa is expected to experience rain and thunderstorms throughout the morning, with residents cautioned against potential lightning strikes and sudden gusts of wind.
