Japanese weather officials are warning of localized heavy rains in eastern and western Japan through Monday. They say people in areas along the Pacific coast should be especially cautious.
Meteorological Agency officials say warm, damp air has been flowing into a seasonal rain front hovering over Japan, making atmospheric conditions unstable in much of the country.
Experts are urging people across Japan to remain vigilant, despite a slight reprieve Monday in recent daily coronavirus numbers. Officials in Okinawa are also concerned over a spike in cases connected to the US military.
Tokyo officials confirmed 119 new cases on Monday. The daily tally had topped 200 for four days in a row. The increase brings the total number of confirmed cases to more than 8,000 in the city of 14 million people.
Tokyo officials say 58 new coronavirus cases were confirmed on Monday. The number of infections has been on the rise in recent days, but the government says there's no need to declare another state of emergency.
The latest figure is slightly smaller than Sunday when the daily tally was the highest since the nationwide state of emergency was fully lifted last month.
Weather officials are forecasting snow in the greater Tokyo area from Monday afternoon through Tuesday. Even a little amount of snow could disrupt traffic in urban areas if it accumulates on roads and railway tracks.
A low-pressure system and a high altitude cold air mass are expected to bring snowfall to wide areas around Tokyo.
