The rainy season in Japan, known as Tsuyu, typically lasts from early June to mid-July, depending on the region. If you are visiting during this time, here are a few things to keep in mind.

Humidity and Heat
The humidity during the rainy season can make it feel hotter than the actual temperature. The combination of heat and moisture can be intense, so be sure to dress lightly and stay hydrated for comfort.
Umbrella
It’s essential to bring an umbrella during this season. You can either bring your own or buy one at most stores. Japan has a wide variety of umbrellas available, from practical to stylish.
Etiquette:
Whether you are using an umbrella or not, always be considerate of those around you. In crowded areas like trains, it’s easy to accidentally bump someone with the tip of your umbrella. Be sure to hold it with the tip facing downward and check your surroundings before opening it.
Seasonal Highlights:
One of the highlights of the rainy season is the blooming of hydrangeas, which can only be seen during this time. Many places in Japan are famous for their hydrangeas.
Enjoy the charm of the rainy season and make the most of your time in Japan!
