Tokyo recorded its 10th consecutive day today with temperatures of 35°C or higher, setting a new record amid Japan’s hottest-ever June and July. Central Tokyo hit 36.0°C, while Hatoyama Town in Saitama soared to 39.4°C. Nearby cities Kumagaya and Koga also saw temperatures near 39°C.
This year alone, Tokyo has logged 23 days above 35°C, another unprecedented milestone, according to weather officials. The extreme heat continues to grip the Kanto-Koshin region and other parts of the country. Authorities are warning of additional weather-related risks, including flooding, river surges, mudslides, lightning, strong winds, and hail.
Extreme heat lingered across Japan on Wednesday, mainly in the eastern region of Kanto Koshin, which includes Tokyo. Central Tokyo has had temperatures of 35 degrees Celsius or higher for the tenth consecutive day, setting a new record.
Daytime highs hit 39.4 degrees in Hatoyama Town, Saitama Prefecture, and 38.7 degrees in Kumagaya City, also in Saitama, and Koga City, Ibaraki Prefecture.
Central Tokyo went up to 36.0 degrees, marking the tenth straight day of 35 degrees or higher. It was also the 23rd day this year with 35-degree-plus temperatures, marking another record.
High temperatures and an inflow of moist air toward a weather front have made atmospheric conditions extremely unstable in the Kanto Koshin region. Thunderstorms were expected through early Thursday. Localized downpours of 60 millimeters per hour were forecast for the northern Kanto region.
Weather officials are urging people to be on alert for flooding in low-lying areas, the sudden swelling of rivers and mudslides, and to watch out for lightning strikes, sudden gusts of wind and hail.
