Japan issues heatstroke warnings as temperatures exceed 35C in east and north
The Japan Meteorological Agency attributes rising temperatures to atmospheric pressure patterns, urging residents to maintain hydration as Typhoon No. 6 approaches southern islands.
Temperatures are rising across eastern and northern Japan, with the Japan Meteorological Agency forecasting extreme heat days exceeding 35 degrees Celsius in some areas. The meteorological body attributes the high temperatures to the presence of high-pressure systems, which have been dominating the weather pattern.
NHK reported on the morning of 1 June 2026 that sunny conditions are expected to persist, further driving up temperatures. This follows a period of severe heat on 30 May, during which widespread areas were predicted to experience hot days exceeding 30 degrees Celsius. Authorities are advising residents to take precautions against heatstroke, including frequent hydration.
The heatwave in the east and north contrasts with developing weather systems in the south. Typhoon No. 6 is forecast to approach Okinawa and the Amami Islands between 1 and 2 June. This system is expected to bring violent winds and heavy rain to regions stretching from Kyushu to the Kanto and Chubu areas.
The impact of the approaching typhoon is already affecting infrastructure, with over 400 flights cancelled through 2 June. The Japan Meteorological Agency continues to monitor the situation as the weather systems shift across the archipelago.
Residents in the affected eastern and northern regions are urged to remain vigilant regarding the extreme heat, while those in the southern and western regions prepare for the arrival of the typhoon. The divergence in weather conditions highlights the complex atmospheric dynamics currently affecting Japan.
