Japan’s rainy season, the early signs of summer

With the rainy season announced last week for western, central, and eastern Japan, summer can be said to have officially begun. While a large part of early summer in Japan is centered around the transition to stay cool in the increasing heat (see the last blog on Cool Biz), Japan’s summer is not merely oppressive heat. Japan’s rainy season brings with it an unstable pattern of unpleasant weather, which some non-Japanese people may be unaccustomed to.

The rainy season lasts from early June to mid/late July in many parts of the country, and is characterized by lots of cloudy weather and rain. Many weather forecasts suggest to always carry a portable umbrella, to prevent getting drenched by a sudden downpour.

Due to the overcast weather and rains, the weather is not continuously hot, so it is always good to be prepared for the mild chill that accompanies an evening squall. However, the humidity rises greatly in the sunny days following rain, which is where Cool Biz becomes very relevant.

Despite the unstable and difficult weather, Japan continues to provide beauty in nature: in many areas hydrangeas can be seen in full bloom in this season (a favorite of yours truly), and irises are also in season during this month. In the second half of the rainy season, lotuses also begin to bloom, signaling the true start of midsummer.

Cloudy weather and rain can often bring about a grey mood, but one’s spirits can be lifted by seeing the vibrant colors of umbrellas around town and the bright blooms of the seasonal flowers.

Enjoy what Japan has to offer, rain or sun, and remember to stay dry!
