From January 22, high pressure will bring calm weather to much of Japan. On January 23, a weak system will pass through northern Japan, followed by a low-pressure system moving east of Japan on January 24, allowing high pressure to extend over the Sea of Japan.

Expect a mix of calm and colder conditions with occasional unsettled weather, particularly in northern areas. Pack warm layers, a coat, and sturdy shoes, with rain gear for potential wet weather in some regions.
