Tokyo has two universally celebrated travel seasons. Cherry blossom (sakura) season runs from late March to mid-April and is the most popular time to visit. Parks including Ueno, Shinjuku Gyoen, and the Meguro River are packed with hanami (flower-viewing) picnickers. Golden Week holiday (late April through early May) brings huge domestic crowds to major attractions; plan around it or book well ahead. Autumn foliage (koyo) from mid-November to early December is the second peak season. Momiji (maple) leaves at Hamarikyu Gardens, Meiji Jingu Gaien, and day trips to Nikko turn the city and surroundings vivid red and gold. June and July bring the tsuyu (rainy season), with frequent overcast days and high humidity. August is hot and humid (30C to 35C) but packed with summer fireworks festivals (hanabi). The sumida River fireworks attract 900,000 spectators. December through February is cold (2C to 10C) with minimal crowds at major temples and shrines. Comiket (Tokyo International Anime Fair) and the Digital Art Museum are excellent winter draws.
