A low-pressure system has brought heavy rain to the northern area of Japan’s main island.
In the past 48 hours, rainfall in the city of Kitaakita in Akita Prefecture has totaled 153.5 millimeters — the average for the month of May.
Warm, humid air flowing into the frontal system from the south is causing unstable atmospheric conditions.

The agency says heavy rain is expected into late Friday night. The regions of Tohoku, Hokuriku and Hokkaido from central to northern Japan may see thunderstorms with severe rain.
Tohoku may get as much as 160 millimeters of rain by mid-Saturday.
