Heavy rain pounded the Kyushu and Chugoku regions early Friday, prompting the Meteorological Agency to issue landslide and flood warnings.

The agency said that rainfall only seen "once every 50 years" had been recorded in Iki, Nagasaki Prefecture, which got 430 mm — roughly 1.6 times the average for June, in the 24-hour period ending at 6:20 a.m. Friday.

That's the heaviest downpour logged since the Meteorological Agency began compiling statistics in 1977.

This inundation caused landslides at 11 places in Iki, leading the municipal government to issue an evacuation advisory late Thursday for the entire city, which has a population of roughly 27,000. The advisory was lifted Friday morning and no injuries were reported.

Hiroshima also issued an evacuation advisory early Friday for the parts of the city hit by severe landslides in August 2014.

According to the agency's forecast, 150 mm of rain was expected to hit northern Kyushu in a 24-hour period through Saturday morning, while 120 mm was expected in the Chugoku region and 100 mm in Kinki.
