Kanagawa Prefecture suffered from flooding Thursday after heavy rain hit Kanto-Koshin and Tokai regions, disrupting train services and leaving a widespread area with unstable atmospheric conditions.
The Meteorological Agency issued warnings for landslides, flooding and thunderstorms with strong gusts or tornadoes in Hokkaido and eastern Japan.
Rainfall of 71.5 mm per hour was registered in Ebina, Kanagawa Prefecture, early in the morning, while heavy rain and thunderstorms in other cities left several streets and houses flooded.
Two of the 28 schools in Hiratsuka were closed and five started late due to hazardous conditions.
Prefectural officials said six houses and restaurants suffered from flooding, one on the ground floor and five in their basements, in the cities of Zama, Yamato, Ebina and Hiratsuka.
Meanwhile, in Yamato and Ebina, as well as Tama Ward in Kawasaki, streets were flooded in around a dozen locations. Rain also triggered a landslide in a vacant lot in Asao Ward, Kawasaki, while a lightning strike in Chigasaki damaged a house roof.
In other areas around Tokyo, heavy rain and thunderstorms prompted several railways to cancel or delay services during the morning rush hour.
Service on the Keio Line, which originates in Shinjuku Station in Tokyo, was halted at around 7:45 a.m. due to lightning. Around 70,000 commuters were affected before trains started running again around 8 a.m.
The Sotetsu Line, which runs between Yokohama and Ebina, was disrupted for an hour and 45 minutes.
Meanwhile, the Tokaido Shinkansen Line was halted for about 30 minutes between Shinyokohama and Odawara, while Odakyu Electric Railway’s Romance Car express trains suffered delays.
On Wednesday, shinkansen service between Mikawaanjo Station in Anjo, Aichi Prefecture, and Maibara Station in Shiga Prefecture was disrupted by heavy rain in Gifu and Aichi prefectures. As many as 34 train runs between Tokyo and Shin-Osaka were canceled and 12 were delayed, affecting 112,000 passengers.
The Meteorological Agency expected the low-pressure system to move toward the Sea of Okhotsk and the cold front to pass through the Tohoku region by Thursday evening, with warm, humid air masses causing unstable atmospheric conditions.
Heavy rain and thunderstorms were expected in a widespread area with local downpours exceeding 50 mm per hour.
From midnight through early Thursday, the city of Shizuoka saw 57.5 mm of rainfall, while 45 mm fell in Kofu, Yamanashi Prefecture, and Nasushiobara, Tochigi Prefecture.
The Meteorological Agency predicted that in the 24 hours to 6 a.m. Friday, up to 150 mm of rain would fall in the Kanto-Koshin region and 120 mm would hit Tokai.
Meanwhile, a record-breaking amount of rain fell Wednesday in Nagoya, causing flooding in streets and houses in most areas of the city, as well as subways.
The torrential rains caused by an extra-tropical cyclone that also struck the Kinki and Chugoku regions left one person missing and five injured. More than 200 houses suffered from severe flooding, prompting officials to issue warnings and evacuation orders for more than 40,000 people.
