From Saturday the 20th to Sunday the 21st, there will be rain and snow on the Pacific side due to the influence of a low pressure system on the south coast. There is a risk of snow accumulation and heavy snow mainly along the mountains. From the 23rd (Tuesday) to the 25th (Thursday), the coldest air of the season will flow in. Snow will fall widely on the Sea of Japan side, and the amount of snowfall may increase.
South coast low pressure from 20th to 21st
The front will remain south of Honshu on Friday the 19th. It is expected to rain in places from Kyushu to Kinki.
From the 20th (Saturday) to the 21st (Sunday), a low pressure system will form above the front, and the low pressure system will move east along the southern coast of Honshu. Rain and snow are expected to fall widely from Kyushu to Tohoku. At the moment, there are many places where it will rain in the plains from Kyushu to Kanto. Snow will fall along the mountains of the Kanto region, Nagano Prefecture, Yamanashi Prefecture, and inland areas of the Tohoku region, and there is a risk of heavy snowfall. Be sure to equip your car for winter and be aware of deteriorating road conditions. Heavy, wet snow can build up on power lines and cause power outages, so it’s a good idea to have a flashlight or something to keep you warm.
The snow and rain caused by the south coast cyclone can vary greatly depending on the cyclone’s course, development, and temperature. The snow area may expand in the future, so please pay attention to the latest information.
Maximum temperatures will be at or below normal. It’s going to feel even colder with the cold rain and snow.

From the 23rd (Tuesday) to the 25th (Thursday), we will have a winter-like atmospheric pressure pattern, and the coldest air of the season will flow in. Cold air with temperatures below -6℃, which is enough to cause snow on even flatlands, is expected to flow into the archipelago at an altitude of 1,500 meters, and even stronger cold air with temperatures below -12℃ is expected to flow into parts of western Japan.
Snow will fall from the Sea of Japan side of Hokkaido to the San’in area, and there is a risk of heavy snowfall. It will also snow in northern Kyushu. The winds are picking up and it looks like it’s going to be a winter storm. Caution and vigilance are required for traffic disturbances caused by heavy snow, snowstorms, and snowdrifts. There will be periods of sunshine on the Pacific side, but there will be places where snow clouds will move in.
Maximum temperatures are likely to be lower than normal in many places. It will be bitterly cold with strong north winds.
