A low pressure system has moved along the southern coast of Japan's main island of Honshu, and has brought heavy snow to wide areas of the Kanto-Koshin region.
The snow has passed its peak, but weather officials say snow is expected to continue in some areas due to a pressure trough and a cold air mass.
The Meteorological Agency says a developing low-pressure system is forecast to move east along the southern coast of the main island of Honshu. It is expected to bring heavy snow to mountains and mountainous areas of the Kanto-Koshin region, which encompasses Tokyo and central Japan.
The Tokyo Fire Department says that as of 9 p.m. on Monday, a total of 40 people aged between four and 92 were injured and taken to hospitals in Tokyo. The injuries are believed to have been caused by snow. No serious injuries have been reported.
There has been a big impact on transportation. Two trains on the Yurikamome driverless line, which runs on an elevated path in Tokyo's bayside area, got stuck in the snow. 550 passengers got off the train and moved to the nearest station on foot. The operator says no one was injured or complained of illness. The line will operate as usual starting with the first scheduled train.
East Japan Railway Company says that some sections of the Chuo Main Line, Ome Line, Hachiko Line, Joetsu Line, Yokohama Line and Agatsuma Line are suspended starting with the first train.
Railway operators are calling on people to check weather conditions and train services, as services may be suspended or significantly delayed on Tuesday, depending on snow conditions.
Japan Airlines canceled 69 flights and All Nippon Airways 37 on Monday, mainly to and from Tokyo's Haneda Airport. They decided to cancel a total of 31 flights on Tuesday.
Weather officials say the snow has passed its peak, but are urging caution against traffic disruptions caused by snow and icy roads.
