Typhoon Linfa, the first typhoon to strike Japan in May since 1965, weakened into a temperate depression Saturday morning, after coming ashore at Uwajima, Ehime Prefecture, the Japan Meteorological Agency said.

JMA officials predicted that the depression will reach the Tohoku Region of northern Japan on Sunday, probably causing heavy rain and landslides.

The season’s fourth typhoon was the third earliest typhoon to hit any of Japan’s four main islands since the agency began keeping standardized typhoon records in 1951.

The typhoon caused the cancellation of about 50 flights as well as landslides and traffic to be halted on several roads, mainly in western Japan, on Saturday morning, police said. Airlines said 102 flights were canceled Friday.

Linfa, also known as Typhoon No. 4, reached Uwajima at around 5 a.m. and weakened to a temperate depression near Kagawa Prefecture at around 9 a.m., the JMA said.

It drenched a wide area of western Japan, from Kyushu to the Tokai region, flooding many homes.

The typhoon triggered 51 mm of rain an hour until 10 a.m. in Omaezaki, Shizuoka Prefecture.

In the 24 hours from 11 a.m. Friday, rainfall totaled 473 mm in Owase, Mie Prefecture; 420 mm in Mihama, Mie Prefecture; and 377 mm in Sakawa, Kochi Prefecture.

In Shimane Prefecture, a 67-year-old newspaper delivery worker was taken to a hospital after being hit by a traffic sign blown down by strong winds, police said.

In Shiga Prefecture, two baby girls in a minivehicle were slightly injured when a piece of flying plywood broke the car’s windows.

On the island of Shikoku, about 4,300 homes were temporarily without power, although Shikoku Electric Power Co. later managed to restore the power supply to almost all the households.

Weather forecasters said that as the depression moves north, as much as 200 mm of rainfall is expected by noon Sunday in some areas of the Tokai region, 180 mm at some locations in Kanto, and between 100 mm and 150 mm in Hokkaido and Tohoku.

In particular, the JMA warned Tohoku residents to be prepared for landslides because heavy rains are expected to contribute to slides in areas shaken by Monday’s powerful earthquake.
