Climate in Japana aries from tropical in south to cool temperate in north. "The weather in Japan is mostly temperate, with four distinct seasons. Winters are cool and sunny in the south, cold and sunny around Tokyo (which occasionally has snow), and very cold around Hokkaido, which is covered in snow for up to four months a year. The Japan Sea coastline also often receives heavy snowfall during winter.

Summer, between June and September, ranges from warm to very hot with high levels of humidity in many areas. Typhoons, or tropical cyclones, with strong winds and torrential rains often hit Japan during August and September, but can occur through May to October. Strong typhoons often affect transport systems, causing rail and air services to be stopped, and there is a danger of landslides in rural areas.

Spring and autumn are generally mild throughout the country, and offer spectacular views of pretty sakura cherry blossoms and colorful autumnal leaves, respectively. Rain falls all over Japan throughout the year but June and early July is the main rainy season. Umbrellas are a daily essential during this season. Hokkaido, however, is generally much drier than the Tokyo area."
