The heavy snow in the capital prompted the Meteorological Agency to issue a warning to all of Tokyo's 23 wards at around 2:30 p.m. the first official heavy snow warning since February 2014. According to the weather agency, the Kanto region is expected to get 10 to 40 cm within the 24-hour period ending at 6 a.m. Tuesday, including 5 to 10 cm in Tokyo's 23 wards.
More than 800 traffic accidents due to the snow were reported. Japan Airlines cancelled 122 flights at Haneda airport, affecting about 15,110 travelers. Weather in the Kanto region will improve from the hour until the end of the week, but snowstorms may reappear next Tuesday.
