* Hokkaido: The northernmost island of Japan, Hokkaido, experiences the heaviest snowfall in the country due to its proximity to the Sea of Japan and cold Siberian winds. Snowfall can start as early as October and continue until April, with the peak snowfall period occurring from January to February.
* Honshu: In the central Honshu region, snowfall varies depending on the location. Areas along the Japan Sea coast, such as the Sea of Japan side of the Chugoku and Kinki regions and the Hokuriku region, receive considerable snowfall due to the influence of cold air coming from the Sea of Japan. Cities like Kyoto, Osaka, and Hiroshima may experience occasional snowfalls, but heavy snow is relatively rare.
* Shikoku and Kyushu: These southern islands of Japan experience milder winters compared to the northern regions, and snowfall is less frequent. Snowfall mainly occurs in mountainous areas and is typically lighter and less consistent than in the northern parts of the country.
