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.

Weekly weather: Rain expected nationwide on Wednesday the 18th; risk of severe winds in northern Japan on Thursday the 19th.

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

2026/11/14 17:18

Tomorrow, Sunday the 15th, a low-pressure system accompanied by a front will move eastward from the waters off the east coast of Kyushu, causing weather conditions to deteriorate across the country. There is a possibility of intense thunderstorms, particularly in the Kyushu and Chugoku regions.



Weather in Northern Japan
In Northern Japan, rain clouds will spread?primarily across the Tohoku region?bringing rain. In Hokkaido, rain is also expected in the southern part of the island. As colder air moves in toward the evening, some higher-altitude areas may see snow.
Maximum temperatures will generally be the same as or lower than today; in Sapporo, the high will be 10C (1C lower than yesterday), making for a chilly day.

Weather in Eastern Japan
In Eastern Japan, a low-pressure system with an associated front will move along the southern coast of Japan. From the afternoon into the evening, active rain clouds are expected to spread, particularly over the southern Kanto region.
In the Izu Islands and the southern part of Chiba Prefecture, there is a risk of intense thunderstorms; please remain alert for potential landslides and flooding in low-lying areas.
Maximum temperatures will largely be lower than today; in central Tokyo, the high will be 14C (5C lower than yesterday), resulting in a chilly day.

Weather in Western Japan
In Western Japan, rain will fall over a wide area throughout the morning. Due to an influx of warm, moist air toward the front, particularly active rain clouds are likely to form over northern Kyushu and the Pacific-facing side of Shikoku, potentially leading to intense thunderstorms.
Conditions are expected to gradually improve from the afternoon onward, with some areas seeing clear skies by the evening.
Driven by the influx of warm air, temperatures in many places will be higher than today; in Fukuoka, the maximum temperature will reach 20C (2C higher than yesterday), making for a comfortable day.

Weather forecast for the Kanto region: Rain is expected across a wide area tomorrow, the 15th, with the possibility of severe weather around the 18th.

2026/11/14 15:55

Here is the weather forecast for the Kanto region.
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.



In the Kanto region, clouds are beginning to spread across the southern areas, but there is no risk of rain tonight.
Tomorrow, a low-pressure system accompanied by a front is expected to move across the waters south of Honshu, bringing rain clouds in from the west.



In the Kanto region, rain will likely begin in many areas starting in the morning; you will likely need to keep an umbrella with you all day.

In the afternoon, the rain is expected to intensify, particularly along the coast, so a sturdy umbrella will be necessary.
In the Izu Islands, heavy rain accompanied by thunderstorms is expected from the evening onwards. Please be cautious of lightning strikes and sudden gusts of wind, such as those associated with tornadoes.
Tomorrow's high temperatures are expected to be around 5C lower than today, Saturday the 14th. Please dress accordingly with a warm outer layer.



/>

Looking ahead, the weather will clear up temporarily on Monday the 16th, but rain is expected on Tuesday the 17th, particularly in the southern regions.
On Wednesday the 18th, a low-pressure system is expected to develop rapidly as it moves across the Sea of ??Japan, bringing stronger rain and winds. Expect driving, sideways-blown rain, so please exercise caution if you have plans to go out-be sure to stay updated with the latest information.
From Thursday the 19th through Saturday the 21st, clear skies are expected across the entire region.



There will likely be significant temperature fluctuations-between sunny days, rainy days, and days when cold air moves into the region. During the latter part of this period, temperatures may drop sharply in the mornings and evenings. Please adjust your clothing accordingly and take care to stay in good health.

Weekly Weather: Rain expected across a wide area tomorrow, Sunday the 15th; potential for stormy weather around the middle of next week.

2026/11/14 08:49

Low-pressure systems and weather fronts are expected to pass near Honshu periodically in the coming days. Around the middle of next week, a rapidly intensifying low-pressure system could bring stormy weather across the country.



Tomorrow, Sunday the 15th, a low-pressure system moving along the southern coast of Honshu will bring rain to a wide area, stretching from Western Japan to Northern Japan. In the Southwestern Islands, rain and thunderstorms are also expected, particularly during the morning.
Along the Pacific coast?from Western to Eastern Japan?expect heavy rain accompanied by thunderstorms. In Kyushu, particularly in areas like Nagasaki Prefecture, there is a risk of extremely heavy rainfall. Please exercise caution regarding potential flooding in low-lying areas and on roads. Additionally, winds are expected to strengthen in some coastal regions, potentially leading to driving, wind-swept rain.



After the low-pressure system passes, a "winter-type" pressure pattern will temporarily develop over the Honshu region on Monday the 16th. In Hokkaido and areas along the Sea of ??Japan coast, this may bring cold rain or snow. By Tuesday the 17th, this winter-type pattern will ease, and much of Honshu?especially in the north?will come under the influence of a high-pressure system. Meanwhile, some areas along the Pacific coast in Eastern and Western Japan may still see rain.

Furthermore, a low-pressure system will approach Honshu from the west on Tuesday the 17th. It is forecast to move across the Sea of ??Japan between Wednesday the 18th and Thursday the 19th, while intensifying rapidly. As a result, around Wednesday the 18th, weather conditions are expected to become severe across the country. In particular, areas along the Sea of ??Japan may experience strong winds or gales, while coastal regions could face high waves significant enough to warrant weather warnings. From Thursday the 19th onward, a "winter-type" pressure pattern is expected to develop, bringing a surge of cold air southward. Consequently, snow or rain may intensify, especially in regions along the Sea of ??Japan, stretching from Northern Japan to the Hokuriku region.




Because the potential impact may vary depending on how much the low-pressure system develops, please stay updated with the latest weather information. Additionally, be sure to check for the most recent transportation updates, as severe weather may cause disruptions.

Today, rain clouds associated with a low-pressure system over the East China Sea are beginning to move into the vicinity of Kyushu.



The weather in Western Japan is set to deteriorate today; in northern Kyushu, rain may begin as early as this morning. By tonight, a front will become stationary over the East China Sea, and the area experiencing rain is expected to spread across Western Japan, from Kyushu through to the Kinki region.




Tomorrow, a low-pressure system along the front will move along the southern coast of Honshu. In Kyushu, the rainfall is expected to peak during the morning hours. There is a risk of extremely heavy, thundery rain in some areas; please exercise caution regarding potential road flooding and the inundation of low-lying land.



Around the 18th of next week, Kyushu is expected to experience rough weather, with intensifying rain and strong winds. Please stay updated with the latest traffic information.

That concludes the weather forecast for the Kyushu region.

[Kyushu: Widespread rain this weekend] When will the rain start? When will it stop? (Analysis by weather forecaster Junko Miyake)

2026/11/13 14:36

"The weather in the Kyushu region is gradually taking a turn for the worse.



Let's start by looking at the current cloud cover.
While clouds have spread across the Kyushu region, they are not particularly thick, and in some places, sunlight is still filtering through the gaps.

However, looking toward the west, there is a large mass of clouds-associated with a weather front and an area of ??low pressure.



By tomorrow (Saturday), this low-pressure system and front will approach the Kyushu region.
Then, on the 15th (Sunday), a low-pressure system along the front is expected to intensify slightly as it passes near the main island of Honshu.

Across the Kyushu region, rain will become widespread from tomorrow afternoon through the 15th (Sunday), with some areas likely to experience steady, heavier rainfall.



Now, let's take a look at the forecast for rain and wind.

By tomorrow morning, rain may begin in parts of northern Kyushu.
Around midday, rain clouds will also move over southern Kyushu.
As the day progresses into the evening, rain is expected to spread across a wide area.



While there will be few places in the Kyushu region experiencing heavy rain through tomorrow,
by the day after tomorrow, Sunday the 15th,
the rain will intensify in parts of southern Kyushu.
In areas around Kagoshima and Miyazaki prefectures in particular,
there is a risk of heavy rain accompanied by thunderstorms.

If you are heading out on Sunday, please bring a large, sturdy umbrella.


Conditions will likely remain favorable for rain through around midday on the 15th.
By evening, however, the rain should taper off across almost the entire Kyushu region.



Now, let's take a look at the weather for each area.
Here is the forecast for today, Friday.

Across the Kyushu region, cloudy conditions will persist.
Temperatures will be quite high-comparable to what is typical for October.
In Naze, the temperature is expected to reach 26C, making it a "summer day" (a day with a high of 25C or above).
Late tonight, rain may begin to fall in places like Fukue, in the Goto Islands.



Here is the forecast for tomorrow, Saturday.
Rain will be widespread; it is expected to begin in the morning across northern Kyushu,
and in the afternoon across southern Kyushu.
Despite the rain, temperatures will remain high-for instance, Fukuoka is expected to reach 20C.



Here is the weekly forecast.
Rain will continue into Sunday, the 15th.
Expect widespread rain until around midday.
Although skies will clear temporarily on Monday, the 16th,
another low-pressure system will approach between Tuesday, the 17th, and Wednesday, the 18th, bringing rain to a wide area.
As this low-pressure system is expected to develop rapidly,
there is a risk of intensifying rain and wind, particularly around Wednesday, the 18th.
Conditions may become severe, potentially causing disruptions to transportation,
so please be sure to stay updated with the latest information.
