Rain season
Tokyo's tsuyu (rainy season) runs June to mid-July — a sustained period of grey, humid days and steady rain rather than dramatic downpours. Typhoon season follows in August–October, when tropical systems can bring intense rain in 24–48 hour windows. Winters are dry, sunny, and cold, with occasional light snow.
