Japan heatwave pushes Hokkaido to 35°C and Kyoto to 36°C

Weather forecasts for July 16‑17, 2026 indicate a heatwave across Japan. In Hokkaido, the city of Kitami recorded a high of 34.6 °C, with forecasts for Kitami and Asahikawa reaching 35 °C and Asahikawa 34 °C. Kyoto is expected to see the nation’s highest temperature at 36 °C. Other regions such as Nagoya, Osaka, Hiroshima and Fukuoka are also projected to hit 35 °C, marking consecutive days of extreme heat.

Meteorological services warned of unstable atmospheric conditions, especially in eastern Japan, the Tohoku region and Kyushu, where sudden heavy rain, thunderstorms and strong gusts are likely on Friday. Residents are advised to stay alert for rapid weather changes and to keep umbrellas handy even if rain isn’t predicted on maps.

Health alerts emphasize the risk of heatstroke and dehydration. Authorities urged people to stay hydrated, avoid prolonged outdoor exposure during peak heat, and monitor vulnerable groups such as children and the elderly. The heatwave follows a period of heavy rain earlier in the week, and a rainy front is expected to bring more precipitation during the upcoming three‑day holiday.
