In addition, on the 10th (Tuesday), the
rainy season front will become more active near western Japan, so there is a risk of heavy rainfall at the warning level in the Kinki region, such as Osaka.


There is a risk of heavy rain during the actual rainy season, so
/Please prepare early for heavy rain, such as cleaning the gutters and gutters today.



The rainy season will begin in the west to eastern Japan one after another through next week, with rainy days expected.


Even with rain, the temperature is high, so be careful when managing your health, such as heat stroke.

Rainy season front moves slowly northwards; in Kyushu, heavy rain at the warning level will occur around the 10th
