On December 25, Japan’s wintry weather will briefly ease as a high-pressure system moves east along the south of Japan. Meanwhile, a low-pressure system will travel northeast from the Sea of Japan. By December 26, this system will pass, and winter conditions will return, becoming more pronounced on December 27.

From December 28 to 29, high pressure from the East China Sea will reduce the wintry weather in western Japan, but northern Japan will continue to experience strong winter conditions with colder air and brisk winds.

No typhoon warnings have been issued for the Tokyo area this week.
