The Kanto region was hit by strong southerly winds on Wednesday, causing disruptions to train services as well as traffic on the Rainbow Bridge.
According to the Japan Meteorological Agency, winds with a maximum speed of 25.2 meters per second were recorded at Haneda airport and 24.9 meters per second in central Tokyo at 11 a.m.
The winds caused the suspension of services on the Saikyo, Sobu, Musashino and Kyoba train lines in Tokyo and outlying areas. The Rainbow Bridge was closed to traffic for a short while in the morning.
The temperature reached an unseasonably warm 21 degrees in Tokyo as of 1 p.m. However, the Meteorological Agency said a cold air mass is expected to move over the Kanto region overnight, bringing temperatures down on Thursday.
