[Snow in the Kanto region] Even if it's sunny now, there are places where a light layer of snow accumulates at night. What should I be careful about

2026/01/29 11:56

The Kanto region is calm and sunny, especially in the plains.

However, the weather changed suddenly on the afternoon of today, the 29th (Thursday), and
it is likely to snow in the plains of the Kanto region tonight, resulting in snow accumulation in some places.



From today's afternoon to tomorrow 30th (Friday), strong cold air will flow over the Kanto region, bringing snow on the flatlands.

In addition, a weak front is expected to pass from the southern Kanto region to the Izu Islands, and snow and rain clouds are likely to develop locally.




Looking at the weather distribution at 3pm,
white snow is expected in western Kanagawa Prefecture and other areas.

There will be a lot of snow mainly along the mountains such as Chichibu in Saitama and Hakone in Kanagawa.

In addition, the snow will become heavier in the plains of the Kanto region by late tonight, and there will be some places where there will be a light amount of snow.

Please be careful of traffic obstructions and frozen roads caused by snow, including in mountainous and plain areas.

If the ground temperature is lower than expected or the amount of precipitation is higher than expected, there is a possibility of
heavy snow.

[Snow Forecast]
There will be heavy snowfall in the 24 hours until 6 a.m. tomorrow, the 30th (Friday),
Mountainous areas in the northern Kanto region 30cm
Flatlands in the northern Kanto region 1cm
From Hakone to Tama region and Chichibu region 5cm
Flat land in southern Kanto region 1cm
Koshin region 40cm
.



Roads are particularly slippery on uphill slopes, curves, bridges, and near tunnel entrances
, making it dangerous to drive at speed.

In areas where snow is expected,
it is best to refrain from driving a car without winter tires.

Cold air and winter-like atmospheric pressure patterns will become stronger through tomorrow, the 30th (Friday). Heavy snow warning.

2026/01/29 09:55

There is a low pressure system with a front over the sea east of Japan, and it is moving away to the east.
There is also a low pressure system near Hokkaido that is slowly moving eastward.
On the other hand, an anticyclone is protruding eastward from the continent.

Today, the low pressure near Hokkaido will slowly move toward the eastern seaboard, and tomorrow, the 30th (Friday), the winter-like pressure pattern of high in the west and low in the east is expected to intensify, causing strong cold air to flow into the upper atmosphere.





For this reason, snow will fall widely on the Sea of Japan side, and there will be places where it snows heavily even on flat areas.
Please be careful of traffic obstructions due to heavy snow and frozen roads, and be careful of snow accumulation and avalanches.

Although there will be many sunny days on the Pacific side, the atmospheric conditions will be unstable due to the effects of cold air in the upper atmosphere and troughs in atmospheric pressure, and it is expected that snow and rain may fall in some places.





###Snow Forecast

This season's strongest and longest cold wave: The long-term winter-like pressure pattern strengthens and the seas near Japan become widespread [Ocean Summary (January 18-24, 2026)]

2026/01/28 15:03

The strongest and longest cold wave of the season has struck, and winter-like pressure patterns have strengthened around Japan for a long period of time.
The spacing between the isobars became narrower, the wind became stronger, and the waves rose in the seas around Japan, causing some places to become barges.
Below is a summary of the ocean (January 18-24, 2026)



#Pressure distribution and waves
On the 18th, the high pressure over the Sea of Japan and the continent moved southeast, and the gradient of pressure became larger between the low pressure west of Hokkaido and the low pressure east of Japan.
The waves rose in the northern Sea of Japan and the east of Japan, and there was a storm in the east of Japan.
From the 19th to the 20th, a low pressure system accompanied by a front developed and moved from the Sea of Japan to the east of the Kuril Islands, while another low pressure system developed west of Hokkaido and moved southward.
The area around Japan gradually entered a winter-like atmospheric pressure pattern, and on the 20th, wave heights reached up to 5 meters in the Sea of Japan, the East China Sea, east of Japan, and west of Hokkaido.
From the 21st to the 24th, a winter-like pressure pattern strengthened for a long period of time.
Waves rose widely in the seas near Japan, and barge conditions continued in the Sea of Japan and east of Japan.



#Sea surface temperature
Sea surface temperatures in the Japanese waters continued to be lower than normal in the northern part.
In the central and western regions, areas with significantly high sea areas shrank and areas that were at normal levels expanded.
The East China Sea continued to be at normal levels.
The southern part of Japan continued to be at normal levels, and the waters off the Tokai and Kanto coasts were slightly below normal.
Off the coast of Sanriku, areas with higher than normal temperatures or significantly higher temperatures have expanded, with temperatures up to 4 C higher than normal.
The temperature off the southeast coast of Hokkaido continued to be higher than normal or significantly higher.
The waters near the Kuril Islands and the Sea of Okhotsk continued to be at normal levels.

[Intense cold air strikes again] Warning-level heavy snow on the Sea of ??Japan side; possibility of snow in southern Kanto Weekly weather forecast

2026/01/28 12:18

Weekly Weather Forecast
#Tomorrow ~ The day after tomorrow, strong cold air will hit again, warning heavy snow on the Sea of Japan side
# Possibility of snow in the southern Kanto region tomorrow
#Cooler than the coldest cold of the year, with temporary high temperatures in early February



#Tomorrow ~ The next day, intense cold air will strike again Warning-level heavy snow on the Sea of Japan side
Last week, the strongest and longest cold air of the season hit, but from tomorrow the 29th (Thursday) to the 30th (Friday), the intense cold air will attack again.
Although not as cold as last week's cold wave, cold air with temperatures around -9c at an altitude of around 1,500m is expected to move southward into western and eastern Japan, and cold air with a temperature of around -12c will move south into northern Japan.
A winter-like atmospheric pressure pattern is strengthening near Japan, and there is a risk of heavy snow mainly on the Sea of Japan side of western and eastern Japan.
Last week's strongest and longest cold wave of the season left a lot of snow in some places, so please be on the lookout for further snowfall.
There will be heavy snowfall not only along the mountains and in the mountains, but also on the flatlands.
In addition, the JPCZ (Japan Sea Polar Air Mass Convergence Line) is expected to remain mostly stationary from the Sea of Japan side of western Japan to Wakasa Bay from next day until the 30th (Friday).



If JPCZ stays in a similar location, there is a high possibility that snowfall will become stronger in a short period of time and become heavy snow.
In the northern Kinki region near JPCZ, snowfall will increase rapidly in a short period of time from noon on the 29th (Thursday) tomorrow to Friday the 30th (Friday).
In particular, if the snow clouds develop more than expected and become stagnant from late at night on the 29th (Thursday) to mid-morning on the 30th (Friday), there is a possibility of warning-level heavy snow.
Depending on the strength of the cold air, there may be warning-level heavy snow in the Sanin and Hokuriku areas near JPCZ, as well as in the northern Tohoku region near the center of the cold air, so please keep an eye on the latest weather information.
It is a good idea to start removing snow and stocking up on food and other items by Wednesday, the 28th, when the snow has calmed down.

#There is a possibility of snow in the southern Kanto region tomorrow.
From tomorrow the 29th (Thursday) to the 30th (Friday), many places on the Pacific side will be sunny.
However, clouds tend to spread around the Tokai region and the southern Kanto region due to the effects of low atmospheric pressure and humid air, and snow and rain are expected to fall in places from around noon tomorrow, the 29th (Thursday).
There will be some snow mixed in along the coast.
There is no need to worry about it accumulating in coastal areas, but you need to be careful about road conditions just in case.



#Cooler than the coldest cold of the year The beginning of February is originally the coldest period of the year, but towards the end of January there will be days when the temperature is even lower than the average cold weather, so it is necessary to protect yourself from the cold.
Mornings are getting colder, so please be careful of frozen water pipes even in inland areas of Honshu.
In early February, temperatures will return to normal in many places, but there will be places in northern Japan that will experience higher-than-normal temperatures for a time.
Be careful of melting snow.

This season's strongest cold wave hits, weather information announcement regarding significant heavy snowfall in Kanazawa, Hikone, etc. (weather summary from January 18, 2026 to January 24, 2026)

2026/01/28 08:31

This is a summary of the weather for this period (January 18, 2026 to January 24, 2026).

#Summary of the weather for this period (January 18th to January 24th)
The average temperature was affected by warm air at the beginning of this period (around the 18th to 19th), but after the 20th there was a shift to a strong winter-like pressure pattern, and the temperature was below normal, especially in northern Japan, which was susceptible to extremely strong cold air. In particular, in northern Tohoku, there were many places such as Aomori where temperatures were 2 C or more below normal.

Precipitation was above normal in many places, mainly on the Japan Sea side from northern Japan to Hokuriku, where a strong winter-like pressure pattern continued and heavy snow fell due to the influence of the low pressure system and JPCZ. On the other hand, in the southern part of Tohoku and the Pacific side of eastern and western Japan, there were many spots with a total rainfall of less than 10 mm during the period, and there was a marked trend of low rainfall, well below normal.

Sunshine hours tended to be below normal on the Japan Sea side from northern Japan to Hokuriku, due to continued snow and rain weather associated with a strong winter-like atmospheric pressure pattern. On the other hand, in western Japan, Okinawa, and Amami, there were many days covered by high pressure throughout the period, so temperatures tended to be above normal.



[About this period's weather]
#Characteristics of pressure distribution
On the 18th, a low pressure system heading south west of Hokkaido later became indistinct, and high pressure prevailed around Honshu. A new low pressure system formed in the western Japan Sea late on the night of the 18th, and continued to develop into the 19th as it moved toward the coast of Sanriku. Another low pressure system formed in the northern Sea of Japan, and by the 20th, a strong winter-like pressure pattern had formed near Honshu, with extremely cold air below -42c at an altitude of approximately 5,500m. The low pressure system accompanied by the front rapidly developed and moved east of the Kuril Islands. On the 21st, the Japan Sea Polar Air Mass Convergence Zone (JPCZ) was formed in the Sea of Japan, and it headed from Hokuriku to the San'in region until the 22nd. In the early hours of the 23rd, a new low-pressure system formed near the west of Hokkaido, and the situation was almost stagnant. After that, the winter-like atmospheric pressure pattern continued around Honshu, and by the 24th, extremely cold air with temperatures below -36c at an altitude of approximately 5,500m moved southward to the Hokuriku region. In the Sea of Japan, the JPCZ continued to be directed from Hokuriku to the San'in area, and developed snow clouds associated with the JPCZ continued to flow into areas from Hokuriku to the San'in area.

#Precipitation
On the 18th, snow fell from northern Japan to Hokuriku, but the area gradually narrowed. In the Nansei Islands, heavy rain was observed due to the influence of a local front. On the 19th, snow and rain fell mainly on the Sea of Japan side from northern Japan to the Sanin area due to the influence of a front and low pressure. On the 20th, snowfall increased in areas around Hokkaido due to the influence of a low pressure system, and 20 cm of snow was observed in Hamakishibetsu in 3 hours. At night, as the cold air moves southward, the snow becomes heavier in Hokuriku and the shadows of the mountains, and on the 21st, heavy snow fell over a wide area along the Sea of Japan. In Sukayu, Aomori Prefecture, the snow depth exceeded 4 meters, and in Kanazawa, weather information was announced regarding extremely heavy snowfall. Even in the flatlands of the southern Kanto region, snow fell temporarily in places such as Yokohama. Around 4 a.m. on the 22nd, weather information was announced regarding significant heavy snowfall, with 25 cm of snow falling in 6 hours in Hikone. On the 23rd, due to the influence of a low pressure system, heavy snow fell in Hamakishibetsu, Hokkaido, with an amount of 21 cm falling in 3 hours. Near Hokuriku, the JPCZ almost stagnated, and developed snow clouds continued to flow one after another. On the 24th, 37 cm of snow was observed in 6 hours in Kuzuryu, Ono City, Fukui Prefecture, and meteorological information regarding significant heavy snowfall was announced.

#Temperature
On the 18th, the temperature was higher than normal in various places due to the influence of warm air.The highest daily temperature in Tokyo was 13.4c in early March, and in Kochi it rose to 18.7c, about the same level as early April. Hikanzakura blooms in Naha. On the 19th, temperatures continued to be higher than normal in western and eastern Japan, and Chinese cabbage bloomed in five locations in western Japan, including Shimonoseki, Takamatsu, and Kagoshima. On the 20th, the warm weather suddenly changed and strong cold air moved south, making winter cold across the country. In central Tokyo, the temperature was 9.0c, 4.8c lower than the previous day. On the 21st, it was bitterly cold across the country, with many places west of the Kanto region below 10 degrees Celsius, and the highest temperature in Kanazawa was 2.8 degrees Celsius. In Osaka, the temperature was 6.1c. On the 22nd, the number of midwinter day observation points reached 371, the highest number of this season (as of January 22nd), and on the 23rd, the number of winter day observation points reached 775, the highest number of this season (as of January 23rd). On the 24th, it was bitterly cold from northern Japan to the Hokuriku region, with the highest temperature in Sapporo being -2.4c, the fifth consecutive midwinter day. Areas west of the Kanto region are hovering around 10 degrees Celsius. The highest temperature in Tokyo was 11.0c, the first time in five days that it exceeded 10c.

Very strong cold air is expected to move south again. There is a risk of warning-level heavy snow from the Hokuriku region to the Sanin region from the 29th to the 30th.

2026/01/28 07:48

From tomorrow the 29th (Thursday) to the 30th (Friday), extremely cold air is expected to flow into the skies above Honshu again. There is a strong winter-like atmospheric pressure pattern near Honshu, and there is a risk of warning-level heavy snow in Hokuriku, northern Kinki, and the San'in area.



Tomorrow, the 29th (Thursday), the strength of the cold air moving south at approximately 5,000 meters above the mainland is very strong, with temperatures below -36c, which is a guideline for heavy snow. In the Sea of Japan, a well-developed belt-shaped snow cloud associated with the Japan Sea Polar Air Mass Convergence Zone (JPCZ) is expected to form, and is expected to remain stagnant as it heads toward the Sea of Japan side of western Japan.



As a result, developed snow clouds will continue to flow into areas on the Japan Sea side, including Hokuriku, northern Kinki, and the Sanin area, and there is a risk of heavy snowfall reaching warning level.
On the Sea of Japan coast from northern Japan to the San'in area, there are already places with snowfall that exceeds normal levels, but it looks like there will be more snowfall in some places from tomorrow the 29th (Thursday) to around the 30th (Friday). There is a risk that snowfall will increase in a short period of time, not only in mountainous areas but also in flat areas.
In addition, some of the developed snow clouds may flow into the Pacific Ocean side of the Tokai region, causing snow accumulation in Sekigahara in Gifu Prefecture and around Nagoya City. Please pay attention to the latest traffic information as there may be a significant impact on transportation.

Please be alert for traffic disruptions and deterioration of road conditions due to heavy snow, and be careful of snow falling from roofs, avalanches, and power outages due to snow accreting on power lines.

#Snow forecast
The expected 24-hour snowfall from 6:00 on the 29th to 6:00 on the 30th is expected to be high in some places,
Hokuriku region 70cm
Kinki region 50cm After that, the predicted 24-hour snowfall from 6:00 on the 30th to 6:00 on the 31st will be heavy in some places,
Hokuriku region 70 cm
Kinki region 40 cm

29th (Thursday) - Intense cold air strikes again. Be wary of further heavy snow after a long cold wave [Weekly weather]

2026/01/27 12:21

Tonight, the flow of cold air will become stronger again,
and the winter-like pressure pattern will become stronger. There is a risk of warning-level heavy snow again in the San'in region, northern Kinki, and Hokuriku regions from tomorrow the 29th (Thursday) to the 30th (Friday).

Please be careful of the impact on traffic, avalanches in the mountains, and snow falling from the roof.

While the effects of the strongest and longest cold wave of the season since last week remain in various places,
strong cold air is expected to start flowing in again from tonight.



#Intense cold air strikes again#

Looking at the low-level cold air forecast for the next six days from tonight, the deep light blue area, the cold air that is expected to bring snow on the plains
(air below -6 degrees Celsius at around 1500m above the ground), is expected to move south from the Sea of Japan side of western Japan to the northern Kanto region tonight.

Furthermore, even stronger cold air (air below -12c at around 1500m above the ground), which is expected to bring heavy snow in flat areas, is expected to move south from the 29th (Thursday) to the 30th (Friday),
, completely covering the Hokuriku and Tohoku regions.

Compared to the long-term cold wave that started around the 21st (Wednesday) of last week,
the period of impact is shorter, but the level of cold air is likely to be about the same level or even stronger in some places.




Looking at the snow forecast for the night of the 30th (Friday),
snow clouds are expected to accumulate mainly from the San'in area to the Sea of Japan side to the north.

From the 29th (Thursday) to the 30th (Friday), there is a possibility of
warning-level heavy snow mainly in the San'in and Hokuriku regions.

Also, the heavy snow is accompanied by strong northerly winds, and the visibility may be poor in some places due to the blizzard.
You need to be very careful when driving a car.

With the strong northerly wind, some snow clouds are likely to flow into the Pacific Ocean.

Around the 29th (Thursday), there will be periods of snow in the Tokai, Kanto, and plains areas.

Please continue to pay attention to the latest snow information.




Finally, the weekly weather.

Currently, it's the coldest time of the year, but the midwinter cold continues into early February.

As there are many sunny days and dry air on the Pacific side,
Please be careful when handling fire.

The cold air is receding, the severe cold is easing and temperatures are typical for this time of year in various places

2026/01/27 07:27

Today, the 27th, a low pressure system is expected to move through the Sea of Japan. The cold air in the sky will recede, and the harsh cold that has been so far will ease.



The predicted maximum temperature is -2c in Sapporo, 7c in Sendai, 10c in Tokyo, 9c in Nagoya, 7c in Kanazawa, 10c in Osaka, 14c in Kochi, and 9c in Fukuoka.

The temperature will be higher in many places than the previous day (26th), but it will likely be cold during the day, especially in eastern and western Japan. Please continue to take measures to protect yourself from the cold when going out and be aware of the temperature difference from the previous day.
On the other hand, in areas with heavy snowfall, the snow is melting in some places, so there is a risk of avalanches and snow falling from roofs. Please be careful of snow melting disasters.

In many places in Hokkaido, it will continue to be midwinter, and the midwinter cold is likely to continue. Please take all possible measures to protect yourself from the cold.

Weather for today, the 27th (Tuesday): Tohoku and Hokuriku are gradually experiencing rain and snow; Kanto and west are mostly sunny.

2026/01/27 06:30

Today, the 27th (Tuesday), the winter-like atmospheric pressure pattern will be relaxed, but a low pressure system is expected to pass from the Sea of Japan to the Tohoku area. There will be rain and snow mainly on the Sea of Japan side. Another low pressure system is expected to move near the Nansei Islands.



In Hokkaido, clouds tend to spread mainly on the Sea of Japan side, and there will be showers of snow mainly in the morning. There are places in southern Hokkaido where it starts to snow in the afternoon, so please be aware of changes in the sky when you go out. It will be sunny in many places on the Pacific side.

In Tohoku and Hokuriku, rain and snow will begin to fall before noon due to the effects of a low pressure system. In many flat areas, it will fall as rain rather than snow, and there is a risk that the snow will melt further. Due to the heavy snowfall that started on the 21st (Wednesday), please be careful of falling snow from roofs, deteriorating road conditions, and avalanches along the mountains in areas with heavy snowfall.

The sky is cloudy and cloudy in the northern Kinki region and in the Sanin area. It would be a good idea to have rain gear when going out.

It is expected to be sunny in many places on the Pacific side from Kanto to Shikoku. Please be careful when handling fire as the air will continue to dry.

Kyushu and Okinawa are prone to rain in the morning due to low pressure. There will be places in Kyushu where you will need an umbrella until the morning and in Okinawa until around noon.
Please be careful of heavy rain and thunderstorms in Okinawa.

A low-pressure system will develop tomorrow, possibly a blizzard on the Sea of ??Japan side of Tohoku Strong cold air will move south again in the second half of the week, leading to warning-level heavy snow [Weekly Weather Forecast]

2026/01/26 12:17

Weekly Weather Forecast
#First half of the week: Winter-type atmospheric pressure is relaxed, and a low pressure system develops
#Second half of the week: Strong cold air moves south again, fear of warning-level heavy snow on the Sea of Japan side
#Starts in February: Clouds are also high on the Pacific side, and rain begins to fall from the west
#Severe cold persists in places with temperatures lower than the coldest cold of the year



#First half of the week A winter-type low pressure system develops due to the loosening of the atmospheric pressure system
The strongest and longest cold air of the season, which caused damage to various places, has finally passed its peak.
Tomorrow, the 27th (Tuesday), the winter-like pressure pattern is expected to loosen and a low pressure system will approach.
A low-pressure system in the East China Sea is moving south of Japan, and there will be some rain in the Nansei Islands and southern Kyushu until the morning.
Also, a low-pressure system in the Sea of Japan will develop and pass over Tohoku, and another low-pressure system will slowly move south west of Hokkaido.
Atmospheric conditions are expected to be unstable in eastern and northern Japan on the Sea of Japan side due to the effects of warm, humid air heading toward a low-pressure area and cold air in the upper atmosphere.
In the plains between San'in and Hokuriku on the Sea of Japan side, there are many places where it rains instead of snow, so be careful about melting snow.
Be careful of avalanches in mountainous areas.
After the low pressure system passes, the cold air will move south, and more areas on the Japan Sea side will turn to snow at night.
Intense snowfall is expected in some places, accompanied by thunder.
There is a risk of a warning-level blizzard on the Sea of Japan side of Tohoku.



#Second half of the week Strong cold air moving south again There is a risk of warning-level heavy snow on the Sea of Japan side
The winter-like atmospheric pressure pattern will return to normal on the 28th (Wednesday), and the winter-like pressure pattern will become stronger from the 29th (Thursday) to the 30th (Friday).
Although not as cold as last week, there is a risk of heavy snow mainly on the Sea of Japan side as strong cold air moves south from the 29th (Thursday) to the 30th (Friday).
Depending on the strength of the cold air, there is a possibility of heavy snowfall in the Sanin and Hokuriku regions, so please keep an eye on the latest weather information.
On the Pacific side, there are few places where it will rain or snow, and the air is expected to remain dry.
Please be careful when handling fire.



#Starting in February The Pacific side is also cloudy and rain begins from the west
On the 31st (Saturday), the winter-type pressure system will loosen, and a low pressure system in the East China Sea will move south of Japan until February 1st (Sunday).
On the Pacific side, the weather is downhill from the west.
Clouds will gradually increase, and rain is expected to occur in the Nansei Islands and the Pacific side of western Japan on February 1st (Sunday).





#The coldest cold of the year continues even in places with temperatures lower than the coldest cold of the year
Tomorrow, the 27th (Tuesday), the winter-like atmospheric pressure will loosen and the cold will ease a little, but midwinter-like cold days will continue into the weekend.
Although it is originally the coldest period of the year, there will be days when the temperature is even lower than the average cold weather, so it is necessary to be fully protected from the cold.
Mornings are getting colder, so please be careful of frozen water pipes even in inland areas of Honshu.
It's exam season, so please don't get sick from the cold.
