Weather officials say the threat of heavy snowfall has eased for central Tokyo, which received only a light dusting through Saturday afternoon as a cold air mass and low-pressure system moved over the area.
Snow started falling across the capital and surrounding Kanto region early on Saturday, accumulating even in some areas on the plains.
Visitors are flocking to the city of Sapporo on Japan's northern island of Hokkaido to see snow and ice sculptures as the annual snow festival kicks off.
The festival, which marks its 70th anniversary this year, is being held in three locations across the city. At its main Odori Park site, the event opened with a trumpet fanfare.
The continued disruption of air traffic caused by heavy snowfall forced more than 40 travelers to spend a night at New Chitose Airport in Hokkaido on Sunday.
The disruption began on Saturday when 105 flights were canceled and about 2,000 people spent the night at the airport near Sapporo in northern Japan.
Heavy snow has forced cancellation of flights to and from Hokkaido, keeping holidaymakers from leaving the northern main island amid the peak of the "U-turn rush."
Airline companies say almost all flights from New Chitose Airport near Sapporo bound for Tokyo, Osaka and Fukuoka were fully booked on Saturday.
