Like other temperate countries, Japan experiences the four seasons. Winter is from December to February, Spring is March to May, Summer is June to August and Autumn is from September to November.

The sakura season typically takes place from the last week of March to the first or second week of April. As such, most of Japan will see a huge surge in both domestic and international tourism. This is also when hotels and other accomodation rates are highest. Popular attractions, such as those in Kyoto, may be extremely crowded as well. If you are not planning to visit Japan specifically to see the sakura blossoms, avoid the period between mid-March to mid-April. In May the weather is warm and can be a little humid.

Japan's wamest months are in July and August, with temperatures reaching as high as 40 degrees Celcius (104 degrees Farenheit).The air is usually humid as well, and as such is not conducive for spending time outdoors. June is less warm but it is also the rainy season.

Perhaps the best time of the year to visit Japan is autumn, as the weather is cool and dry, with little rain. Tree leaves start to take on autumn hues of red and orange in the beginning of September, and this might last until early December in some places.

Winter in Japan is typically cold and dry, with little snow if at all on the main Honshu island.  The ski season is typically considered late December to late March. However there are resorts that only operate during Spring and Summer as during Winter the roads are inaccesible due to the heavy snowfall.  It is best to wear plenty of layers during winter as sudden strong winds can make temperatures plummet very quickly. If the weather gets too cold for comfort, most convenience stores and drug stores will have warm packs for sale.
