Tokyo

Spring (Mar–May): Mild, cherry-blossom season (late Mar–early Apr). Very pleasant weather but extremely popular—expect crowds and higher prices around sakura and Golden Week (late Apr–early May). Summer (Jun–Aug): Starts with a rainy season in June, then hot, humid July–Aug. Tourist crowds spike for fireworks (Sumida River), festivals and Obon in August; humidity can be uncomfortable but festival atmosphere is lively. Autumn (Sep–Nov): Cool, comfortable temperatures and clear skies. Foliage peaks Nov–early Dec; fewer international crowds than spring, making it a great shoulder season. Events include autumn illuminations and Halloween street scenes in Tokyo. Winter (Dec–Feb): Cold but dry with crisp blue skies. Low tourist volumes except New Year (late Dec–early Jan), when many businesses close. Enjoy winter illuminations and seasonal markets.
