The Japan Meteorological Agency calls for caution against sediment-related disasters, low land inundation, and river flooding.
Also, in western Japan, you need to be careful about severe gusts such as lightning strikes and tornadoes.
According to the Japan Meteorological Agency, the Baiu front in the south of Japan will move north on the 27th, and a low pressure system will be created on the front, which is expected to increase the inflow of warm and moist air.

The amount of rainfall in the 24 hours until the morning of the 27th is expected to be 150 mm in northern Kyushu where there is a lot of rain.
It will continue to rain after that, and it is expected to be 100 mm to 200 mm in Tokai, Kinki, and Shikoku regions, and 100 mm to 150 mm in northern Kyushu and southern Kyushu in the 24 hours until the morning of the 28th.
