At least four people have died in eastern Japan as heavy rain flooded roads, cut power and left thousands of travelers stranded overnight at Tokyo's Narita airport, authorities said Friday.
More than 36 centimeters (14 inches) of rain fell in 24 hours in parts of Chiba prefecture, which borders Tokyo, triggering landslide warnings and power outages for nearly 25,000 households.

A JMA official on Thursday said this was "shaping up to be an unprecedented level of heavy rain."
