The rainy season is finally here…

June in Japan sees the start of 梅雨 (tsuyuu) or “rainy season” as it’s come to have been known in English. If you ask the locals, June is the last month that they would recommend to visit. After starting in the middle of June, the rainy season lasts about six weeks and believe us, it is truly painful.

We actually were starting to think that we had avoided it by some miracle this year as June has been very dry so far. However, sadly we were mistaken when the rain and humidity came to Nagoya this week!

The only place to escape is the northern most prefecture of Hokkaido where temperatures remain in the mid-20Cs throughout the summer.

The following table shows the average starting and ending dates of the rainy season for selected regions of Japan, according to the Japan Meteorological Agency:

Region Start End
Okinawa May 8 June 23
Southern Kyushu May 29 July 13
Shikoku June 4 July 17
Kansai (incl. Kyoto) June 6 July 19
Kanto (incl. Tokyo) June 8 July 20
Northern Tohoku June 12 July 27

The rainy season in Japan is is caused by the collision of northern and southern air systems and produces, surprisingly, a lot of rain. The problem for us humans is the humidity at this time of year – you cannot leave your house without dripping almost instantly. A truly tough six weeks.

It doesn’t actually rain every day during rainy season, with Tokyo registering around an average of 12 rainy days in June – that said we did just say it starts in the middle of that month! Let’s just say it’s not the best time of the year so がんばります! (Try your best!).
