Weather forecasts for Sunday, May 24, predict a high of 21°C [1] in Tokyo and summer-like heat across western Japan.
The shifting patterns indicate a sharp divide in regional conditions, with some areas experiencing early summer warmth while others face deteriorating weather due to an approaching low-pressure system.
In western Japan, daytime temperatures are expected to rise by approximately two degrees Celsius [4] compared to Saturday. This trend is bringing summer-like conditions to the region, with Osaka forecast to reach a high of 28°C [2].
Conversely, residents on the Sea of Japan side, including the Hokuriku region and northern Japan, should expect declining weather. The approaching low-pressure system is likely to bring rain to areas such as Kanazawa, where the high is forecast at 25°C [3], as well as Aomori and Akita [6].
In the north, Sapporo in Hokkaido is expected to see a high of 17°C [5].
"Tokyo is expected to be 21°C," TBS NEWS DIG said [1].
Regarding the regional heat, TBS NEWS DIG said that in western Japan, daytime temperatures will be around two degrees Celsius higher than today in many places, resulting in summer-like heat [4].
For those in the Hokuriku and northern Japan Sea regions, TBS NEWS DIG said the weather is on a downward trend due to the influence of the approaching low-pressure system [6].

The contrast between the summer-like temperatures in western Japan and the instability caused by the low-pressure system in the north highlights the volatile transition into the summer season. This meteorological split requires residents to prepare for vastly different conditions, ranging from heat-mitigation in the west to rain precautions in the Hokuriku and northern coastal regions.
