Around the 18th–20th, a rapidly intensifying low-pressure system is expected to bring severe weather nationwide, with the potential for disruptions to transportation services.

2026/11/15 17:43

From Wednesday the 18th to Friday the 20th, a low-pressure system is expected to develop rapidly as it moves from the Sea of ??Japan toward the Sea of Okhotsk. Expect rough weather nationwide, with intensifying rain, snow, and strong winds.
As this may impact transportation services, please be sure to check for the latest updates frequently.



From Wednesday the 18th to Friday the 20th, a low-pressure system is expected to develop rapidly as it moves from the Sea of ??Japan toward the Sea of Okhotsk.
Consequently, the entire country will likely experience rough weather, with strengthening rain, snow, and high winds; sea conditions may also become turbulent.

On Wednesday the 18th, a low-pressure system and a cold front will pass over Japan, bringing rain across the country. Strong winds will likely cause the rain to fall sideways (driving rain).
Around Thursday the 19th to Friday the 20th, a "winter-type" pressure pattern will emerge. The pressure gradient-the difference in air pressure-will sharpen between the low-pressure system and a high-pressure system extending from the Asian continent, leading to persistent strong winds nationwide. Much of Hokkaido will see snow, while the Sea of Japan side of Honshu will experience rain. Around Friday the 20th, a strong cold air mass is expected to move in from above; in regions such as Tohoku, Hokuriku, and the San'in area, precipitation may turn to snow, particularly at higher altitudes.







[Disaster Prevention Advisory]
In Northern Japan, please be on high alert for violent winds and high waves around Thursday the 19th, and exercise caution-or remain on high alert-regarding heavy snowfall around Friday the 20th.
Along the Sea of Japan coast from Eastern to Western Japan, please exercise caution-or remain on high alert-for violent winds and high waves between Thursday the 19th and Friday the 20th.





As rain, snow, and winds intensify, transportation services may be affected. It is advisable to take precautions against heavy snowfall and violent winds now, and to consider adjusting your plans if necessary.
Additionally, please stay updated on any disaster-related weather information issued in the coming days.

Winter-like pressure pattern to intensify following rain; widespread rough weather expected mid-week.

2026/11/15 15:41

There are low-pressure systems over the Sea of ??Japan and to the south of Shikoku, both moving toward the east-northeast.
A strong high-pressure system remains stationary over Siberia, extending its influence toward Japan.
Currently, much of Japan is covered in clouds, with rain falling across a wide area?from the southern part of Hokkaido to western Japan.



Today, both low-pressure systems will continue moving eastward. From the afternoon onwards, areas including Hokuriku, Tokai, and Kanto may experience periods of heavy, sudden rainfall.



In western Japan, the rain will taper off by the afternoon, and the weather will gradually improve.
In Hokkaido, precipitation is expected to turn into snow or sleet by the evening.

Tomorrow, the high-pressure system extending from the Asian continent will strengthen, creating a 'winter-type' pressure pattern over Japan.
As the pressure gradient increases, please be cautious of strong winds, particularly from northern Japan through to the Tokai region.



While the Pacific side and western Japan can expect sunny skies, the Sea of ??Japan side will remain cloudy, with rain likely in some areas.

From around the 18th (Wednesday) to the 19th (Thursday), a developing low-pressure system is expected to bring rough weather across a broad area, stretching from northern to western Japan.






Around the 19th, severe weather is expected, particularly in Northern Japan, where very strong winds and rough seas are likely.
Depending on the intensity of the developing low-pressure system, areas along the Sea of ??Japan coast?from Eastern to Western Japan?may also experience severe weather and rough seas.

In Northern Japan, please remain on high alert for violent winds and high waves around the 19th. In areas along the Sea of ??Japan coast from Eastern to Western Japan, please exercise caution and stay alert for strong winds and high waves around the same time.
Please stay updated by frequently checking any warnings, advisories, or weather information issued in the coming days.

Weather forecast for the Koshin-Hokuriku region: Potential for stormy weather on the 18th–19th due to a developing low-pressure system.

2026/11/15 15:35

Here is the weather forecast for the Koshin-Hokuriku region.
There are three low-pressure systems in the vicinity of Japan, all moving toward the east-northeast.
In the Hokuriku region, the influence of a low-pressure system moving across the Sea of ??Japan-along with a trough-is bringing rain to a wide area.





As the main rain clouds are expected to shift eastward, the rain will taper off in many areas by this evening. However, as a "winter-type" pressure pattern (characterized by high pressure to the west and low pressure to the east) gradually develops through tomorrow, Monday the 16th, some rain may persist in areas along the Sea of ??Japan coast.

By tomorrow, Monday the 16th, the low-pressure systems will have moved away to the east of Japan, and the region will come under the influence of a winter-type pressure pattern. In the Koshin-Hokuriku region, cold air and moisture will likely lead to increased cloud cover along the Sea of ??Japan coast, with some areas-particularly during the morning-experiencing rain.
High temperatures will be similar to or slightly lower than today's, remaining around the seasonal average. In Kofu, the temperature is expected to reach 19C, making it warmer than today.



Here is the weather forecast for the coming week.
On Tuesday the 17th, Northern Japan will be under the influence of a high-pressure system, though it will be relatively weak. Meanwhile, in the Koshin and Hokuriku regions, moist air circulating around the edge of this high-pressure system is likely to bring increased cloud cover; rain is expected in Kofu.

From Wednesday the 18th to Thursday the 19th, a low-pressure system is expected to develop rapidly as it moves northeast across the Sea of ??Japan.
Rain is likely to become widespread on Wednesday the 18th. By Thursday the 19th, while Kofu may see clear skies, rain is expected in Nagano and the Hokuriku region. Winds will strengthen-particularly along the Sea of ??Japan coast-potentially leading to rough weather. Waves at sea will also build. Depending on the intensity of the low-pressure system, there is a risk of warning-level gale-force winds and high waves. Please stay updated with the latest information and take necessary precautions early.

Following the passage of this low-pressure system, a "winter-type" pressure pattern will set in. Around Friday the 20th, a strong cold air mass is expected to move in at higher altitudes. Across the Sea of ??Japan side-including the Hokuriku region-widespread rain is anticipated, with some areas at higher elevations likely seeing a transition to snow.



Around Friday the 20th, temperatures will drop significantly, with many areas remaining in the single digits (Celsius) even during the day. In Kofu and Nagano, minimum temperatures are expected to fall to near 0C. Please take this opportunity to prepare for winter and ensure you are ready for the cold.

A low-pressure system is expected to develop rapidly around the 18th–19th; be on alert for severe storms and high waves, particularly in Northern Japan - take precautions against the high winds well in advance.

2026/11/15 13:56

From Wednesday the 18th to Thursday the 19th, a low-pressure system is expected to move northeast across the Sea of Japan while intensifying rapidly.
The Japan Meteorological Agency has issued a general weather advisory regarding this developing system. It warns that around Thursday the 19th, conditions could become severe?particularly in Northern Japan?with the potential for very strong winds and rough seas.
Please take precautions against high winds as soon as possible.



From Wednesday the 18th to Thursday the 19th, a low-pressure system is expected to move northeast across the Sea of Japan while intensifying rapidly.
As a result, rain or snow and strong winds are expected across the country, with rough sea conditions likely in some areas.

As shown in the projected weather map, the isobars around Japan are expected to become very tightly packed by Thursday the 19th.
In Northern Japan, in particular, there is a risk of very strong winds and rough seas; please remain on high alert for severe gales and high waves. Caution is also advised for areas along the Sea of Japan coast in Eastern and Western Japan.
Because there is a possibility of heavy snowfall, severe winds, or high waves reaching warning levels, please check for the latest updates frequently.



# What is meant by "very strong winds"?
The term "very strong winds" refers to conditions with an average wind speed of 20-30 m/s, with the potential for instantaneous gusts reaching 30-40 m/s. The wind is strong enough that you may be unable to stand without holding onto something, and there is a risk of injury from flying debris. Driving at normal speeds will also become difficult.
Furthermore, the wind is powerful enough to cause signs to fall or roof tiles to be blown away.

# Take early precautions against severe winds
When severe winds are forecast, it is essential to take precautions well in advance.
Take this time to inspect items kept outdoors?bring them inside if necessary?and prepare for potential power outages.
Additionally, stay updated by checking for any changes to your plans and monitoring the latest information regarding public transportation services.

Key measures for dealing with severe winds include:
#Bring items such as laundry poles and potted plants from your balcony or veranda indoors.
#Secure bicycles and motorcycles kept outdoors.
#Move vehicles to a safe location where they are not at risk from flying debris or falling trees.
#Reinforce windows (e.g., by applying shatterproof film or tape).
#Prepare for power outages caused by downed power lines: have flashlights, charged mobile power banks, spare batteries, and warm clothing on hand.
#Inspect trees; prune them or install support stakes to prevent them from falling.
#For agricultural facilities, inspect and reinforce greenhouses (vinyl houses), and check fruit trees, securing them with stakes or similar supports.

2026/11/15 09:09

Next week, a "winter-type" pressure pattern?characterized by high pressure to the west and low pressure to the east?will frequently dominate, bringing a high likelihood of rain or snow to the Sea of ??Japan side of the country. On the Pacific side, humid air and passing low-pressure systems may also bring periods of rain. In particular, on Wednesday the 18th, a low-pressure system will move across the country, bringing rain nationwide. By Thursday the 19th, there is a risk of severe winds, especially in Northern Japan; please stay updated with the latest weather information.



Monday the 16th ? Tuesday the 17th: Rain or snow on the Sea of ??Japan side; some rain on the Pacific side
At the start of the week, on Monday the 16th, a temporary "winter-type" pressure pattern will develop. Clouds will likely spread across Honshu, with intermittent rain expected on the Sea of ??Japan side. Hokkaido may also see periods of snow or cold rain.
On Tuesday the 17th, while much of Honshu will be under the influence of a high-pressure system, some areas along the Pacific coast?from Eastern to Western Japan?may experience rain. This is due to humid air circulating around the edge of the high-pressure system, combined with the influence of a low-pressure system located over the sea west of Kyushu.

Wednesday the 18th ? Thursday the 19th: Unsettled weather nationwide; caution advised for severe winds in Northern Japan
From Wednesday the 18th through Thursday the 19th, a low-pressure system moving from the Asian continent is expected to intensify rapidly as it travels toward Sakhalin. Consequently, rain is expected across the country on Wednesday the 18th.
By Thursday the 19th, the weather pattern will shift toward a typical "winter-type" configuration. The Pacific side of Honshu may see periods of rain, while snow is expected on the Sea of ??Japan side of Hokkaido. As a low-pressure system develops, winds will strengthen across the country. Caution is advised regarding severe winds, particularly along the Sea of ??Japan side of northern Japan. Please stay updated with the latest weather and transportation information.

Friday, the 20th ? Saturday, the 21st: Rain or snow along the Sea of ??Japan; clear skies from the Kanto to Tokai regions.
On Friday, the 20th, a "winter-type" pressure pattern?characterized by high pressure to the west and low pressure to the east?will take hold. By Saturday, the 21st, a low-pressure system is expected to move east of Japan. Across Honshu, rain is likely, especially along the Sea of ??Japan side, with some areas in the Tohoku region potentially seeing snow. Snow is also expected in Hokkaido, primarily along its Sea of ??Japan coast. Meanwhile, the Pacific side of western Japan will likely see an increase in cloud cover, while the Pacific side of eastern Japan?including the Kanto and Tokai regions?is expected to remain generally clear.

Weather for today, Sunday the 15th: Rain across the country due to a low-pressure system and a front; heavy rain possible in some areas.

2026/11/15 07:09

Today, Sunday the 15th, a low-pressure system and a front will pass near Japan, bringing rain to various regions. In some areas, the rain may become heavy, so please be cautious of potential heavy downpours. Additionally, in the Kanto and Tohoku regions, temperatures will remain low throughout the day, with many areas failing to reach 15.



In Western Japan, rain is expected in many areas during the morning, with the possibility of heavier rainfall along the Pacific coast. Caution is advised in the Amami and Okinawa regions, where heavy rain is also possible.

By the afternoon, the rain will gradually taper off as conditions improve; in Kyushu and Shikoku, skies are expected to clear up further from the evening onwards. High temperatures will reach 20 or above in Kyushu and Shikoku?where the weather will clear up sooner?and hover between 18 ??and 20 in the Chugoku and Kinki regions, meaning it will not feel particularly chilly.

In the Tokai and Hokuriku regions, rain will fall from the morning, while in the Kanto and Tohoku regions, the rain is expected to intensify. Along the coasts from Tokai to Kanto, as well as in the Izu Islands, some areas may experience heavy rain accompanied by thunderstorms. In the Kanto and Tohoku regions, temperatures will not rise much during the day; many places will stay below 15, with some areas seeing temperatures typical of early December.



It will likely feel chilly throughout the day. If you are heading out, it is recommended to bring a warm, thick outer layer.

Rain will spread from the west tonight, covering a wide area by tomorrow, the 15th; be alert for thunderstorms along the Pacific coast.

2026/11/14 17:33

Tonight, the area affected by rain will gradually expand from the west, and by tomorrow, Sunday the 15th, rain or snow is expected across the entire country. Rainfall is likely to intensify, particularly along the Pacific coast, so please take care if you are heading out.



Low-pressure systems are currently located off the southeastern coast of the Kanto region and near the Tsushima Strait, both moving in an east-northeasterly direction. Additionally, a front extends across the East China Sea.



Rain has already begun to fall across a wide area of ??Western Japan.
In Izuhara, Tsushima City (Nagasaki Prefecture), 27.0 mm of heavy rain was recorded in the hour leading up to 2:43 PM.

Looking ahead, a low-pressure system is expected to form along the front in the East China Sea and pass over southern Kyushu by the morning of tomorrow, Saturday the 15th. It will then continue moving east-northeast off the southern coast of Honshu throughout the day.



Tonight, the area affected by rain will expand across Western Japan, and rain is also expected to begin in parts of the Tokai and Hokuriku regions.
Tomorrow, Sunday the 15th, rain will start in the Kanto region and from the Hokuriku region through to the Tohoku region in the morning, while Hokkaido will see rain or snow beginning in the afternoon.
Although the weather is expected to improve from the west by the afternoon, rain is likely to persist along the Sea of ??Japan coast through the day after tomorrow, Monday the 16th.





In some areas?primarily along the Pacific coast?there is a risk of heavy rain accompanied by thunderstorms.
As warm, moist air flows toward a weather front and an area of ??low pressure, atmospheric conditions will become highly unstable across southern Kyushu, the Amami Islands, and Okinawa. Please remain cautious regarding the risks of landslides, flooding in low-lying areas, and rising river levels. Additionally, be alert for lightning strikes, severe gusts (such as those associated with tornadoes), and sudden, intense downpours.

[Rain nationwide] Weather for tomorrow, Sunday the 15th: Heavy thunderstorms possible in the Kyushu and Shikoku regions
