The rainy season has begun. Rainy season essentials. 2021’s rainy season will be different!

rainy season in Japan

On May 16, 2021, the meteorological observatory announced that the rainy season has started in the Kinki and Tokai regions. I live in the southern part of Kyushu, where the rainy season has already started on May 11.

It is said that Japan has four distinct seasons, but the rainy season lasts for about a month after spring. We don’t have a rainy season in Hokkaido, but I was curious, so I looked up the rainy season.

As you can see from the table, the rainy season is more than two weeks earlier than usual. The rainy season in Japan does not mean that it rains every day. It is more like a rainy season. By the way, today in southern Kyushu, the room temperature is 29 degrees Celsius and it is sunny outside with no sign of rain. Yesterday, it rained on and off all day.

In the rainy season, the humidity is high and the days are annoying. Just when you think it’s going to be sunny, it suddenly starts to rain, and you can’t go out without your umbrella. Riding a bicycle with an umbrella is now prohibited, so if you want to ride a bicycle, you have to wear a raincoat.

When I was a high school student riding my bicycle to school, there was nothing I hated more than having to wear a raincoat on a rainy day. I used to have a hard time just taking off my kappa(raincoat) because of the rain. The rainy season, which does not belong to any season, does not last more than about a month, and it is not pleasant.

So, I thought about what I would need to survive the rainy season.


You will need a folding umbrella and a regular umbrella. This is because even if it is not raining when you go out, there is a good chance that it will start to rain. People in other countries often don’t take an umbrella when it rains a little, but without an umbrella, you will get soaked in the rain in Japan.
