A shift in weather patterns is expected across Japan on April 16, 2026. While rain is forecast for the Tohoku and Kanto regions until morning, conditions are expected to improve by midday. Hokkaido and areas from the Tokai to Kyushu regions are anticipated to see mostly sunny skies. Residents in the Pacific-facing areas of the Tokai to Kyushu regions should prepare for warmer temperatures, with highs potentially exceeding 25°C in some locations and take precautions against heatstroke.
Rainy Start for Eastern Japan
A low-pressure system accompanied by a front will move eastward over the sea off Kanto, giving way to a high-pressure system covering much of Japan. This means Hokkaido will experience generally clear weather. However, the Tohoku and Kanto regions will see rain through the morning due to the influence of the low-pressure system and moist air. Residents are advised to remember their umbrellas for their commute. The Tokai to Kyushu regions will see clouds dissipate by morning, leading to sunny conditions.
Summer-Like Temperatures in Western Japan
Areas from the Tohoku, Kanto, and Hokuriku regions that experience morning rain may not see a significant increase in temperature compared to April 15th. The high in central Tokyo is forecast at 23°C, 1°C lower than today. Conversely, the Tokai to Kyushu regions, experiencing earlier clearing skies, will see rising temperatures, particularly on the Pacific side. Nagoya is expected to reach 27°C on April 16th, an 8°C increase from today. Kochi and Kagoshima are as well forecast to reach summer-like temperatures of 26°C and 27°C respectively. Residents should be mindful of heatstroke and take preventative measures such as wearing hats, using umbrellas, and staying hydrated.
Prepare Air Conditioners for Warmer Weather
Before temperatures consistently rise, It’s recommended to test air conditioners to ensure they are functioning properly. Demand for air conditioner repairs and installations typically surges as summer approaches, potentially leading to delays in purchasing and installing new units. A malfunctioning air conditioner during hot weather can increase the risk of heatstroke. It is advisable to clean the air conditioner filter before testing it.
