Is September a good time to visit Tokyo?
Mixed weather: comfortably warm and wet. September is usually shoulder season in Tokyo: fewer crowds than peak months, with prices often a little lower.
Our rule: a month scores 2 points for comfortable average highs of 18–28 °C (1 point for 14–18 or 28–32 °C) and 2 points for 5 or fewer rainy days (1 point for 6–10). Average highs above 35 °C or below 8 °C make it a tough month whatever the rain. A rainy day here means 2 mm of rain or more. 4 points = great, 3 = good, 2 = mixed, 0–1 = tough.
