Typhoon 15 is forecast to make landfall in the Kanto region this Tuesday afternoon, bringing strong rain and wind to eastern Japan [1].
The storm's arrival threatens to disrupt transportation and safety across the Kanto and Tohoku regions, coinciding with a severe heatwave in the west.
Meteorologists said the typhoon's approach is bringing strong low-level winds and abundant moisture [2]. When this moisture combines with upper-level cold air, it creates unstable atmospheric conditions that trigger heavy precipitation [2].
Forecasters said significant rainfall is expected across several regions. The Tohoku region is projected to see approximately 180 mm of rain [1], while the Kanto-Koshin region is expected to receive about 150 mm [1]. These totals increase the risk of localized flooding, and landslides as the storm moves inland.
Temperature forecasts vary significantly by region. In Tokyo, the temperature is expected to be 28 °C [1], and Sendai is forecast at 26 °C [1]. However, the storm's position is leaving other areas exposed to intense heat. Temperatures in Tokai and western Japan are expected to reach around 35 °C [1].
Weather officials said conditions will remain unstable through Wednesday. This instability may lead to further intense rain and thunderstorms across the archipelago as the system evolves.
Residents in the path of the storm are advised to monitor local alerts and prepare for wind-driven rain. The combination of a tropical cyclone in the east and extreme heat in the west creates a complex weather pattern for the country this week.

The simultaneous occurrence of a landfall-capable typhoon in eastern Japan and extreme heat in the west puts significant strain on national emergency services. The heavy rainfall totals in Tohoku and Kanto-Koshin increase the likelihood of infrastructure failure and landslides, while the 35 °C temperatures in the west heighten the risk of heatstroke for the population.
