Weather forecast for July in Tokyo

Hello, I'm a Korean living in Beijing.

Generally, the rainy season begins in mid-July. But Jeju Island ended before Seoul.

So if you go to two places, first go to Seoul, and then go to Jeju Island.

Two other places are wet, so you have to take an umbrella. It must be very hot to arrive in Jeju Island at the end of July.
