Rainy season is called “Tsuyu (梅雨)” in Japanese. It literally means “Plum Rain” , the reason being that the plum fruit ripens during this time of the year, and we have a lot of rain during these months.
The Meteorological Agency officially announces the beginning and end of Tsuyu every year, and here is this year’s forecast by the Weather News Company (Japanese page) for the Tokyo area.
- Forecast for 2009 From Jun. 8 to Jul. 16
- Last year May 29 Jul. 19
- Average year Jun. 8 Jul. 20
[ It will rain gently and softly and the temperature will be lower than average in June. Early July will be hot and humid, a bit of a break from the rain and towards the end, it is expected to rain rather heavily. ]
