Friday, the 13th: Beware of thunderstorms and gusty winds in the Hokuriku region; Kanto-Koshin to see fair, calm weather.

2026/11/13 06:53

A low-pressure system with an associated front is located near Sakhalin and is moving eastward.
The area around Honshu is covered by a broad, band-like high-pressure system, with centers located southeast of the Kanto region and near the Tsushima Strait.
A small low-pressure system is situated south of the Kii Peninsula and is moving slowly toward the east.



Currently, there is a band of precipitation across Akita, Yamagata, and Iwate prefectures, with some areas experiencing rain accompanied by thunderstorms.
Additionally, due to the small low-pressure system, there is localized rain occurring on the Kii Peninsula.



Today, the Kanto-Koshin region will be generally clear, with no expected deterioration in the weather. Temperatures will rise during the day, leading to pleasant, comfortable conditions.



While the rain clouds near the Kii Peninsula are expected to gradually move away toward the southeast, those in the Hokuriku region should remain cautious of lightning, sudden gusts, and brief, heavy downpours through around midday.

/>

The weather will begin to deteriorate from the west tomorrow, and by Sunday the 15th, rain is expected across a wide area.



From Tuesday the 17th through Thursday the 19th, a developing low-pressure system will bring rain to a large portion of the Honshu region. Winds may strengthen as this system passes through.
Please stay updated with the latest information.

Rain expected across a wide area this weekend; unsettled weather likely to continue into next week.

2026/11/12 19:10

The area around Japan is covered by a broad, belt-like expanse of high pressure, with centers located south of the Kanto region and over the East China Sea.




Currently, rain or snow is falling in parts of Hokkaido, Yamagata Prefecture, and Niigata Prefecture. The Kanto-Koshin region is generally clear, while clouds have spread across Western Japan.

Tonight, the weather in the Kanto-Koshin region is expected to remain stable. In Northern and Western Japan, however, clouds will spread, and there may be scattered showers in Hokkaido, along the Sea of ??Japan side of the Tohoku region, and in the Chugoku and Shikoku regions.

Tomorrow, the area around Honshu will remain under the influence of high pressure, leading to mostly calm, clear weather during the day. On the other hand, along the Sea of ??Japan side of the Tohoku region and in the Tokai region, there is a risk of intermittent rain or thunderstorms, particularly during the morning hours.





On Saturday, the weather will begin to deteriorate from the west, and by Sunday the 15th, rain is expected to spread across a wide area. Furthermore, from Tuesday to Thursday of the following week, the passage of a low-pressure system may bring rain to a large portion of the area around Honshu.

[One-Month Forecast] Temperatures are expected to be higher than average across eastern and western Japan as the region remains prone to being covered by warm air; conditions are also likely to be influenced by low-pressure systems and fronts.

2026/11/12 17:54

The Japan Meteorological Agency (JMA) released its one-month forecast today, Thursday the 12th, covering the period from November 14 to December 13.

Over the next month, the entire country is likely to be covered by warm air, with temperatures expected to be higher than average, particularly across eastern and western Japan.
Additionally, as the country will be prone to the influence of low-pressure systems and fronts-especially during the early part of this period-precipitation is expected to be above average along the Pacific coast of northern Japan and the Sea of Japan coast of eastern Japan. Along the Sea of Japan coasts of northern and western Japan, precipitation will likely be near or above average.



Regarding the one-month average sea-level pressure (left chart), higher-than-normal pressure is expected south of Okinawa, while a trough (an area of ??low pressure) is forecast to extend from the Sea of Japan toward Hokkaido. The entire country is likely to be affected by low-pressure systems and fronts, particularly during the beginning of the period.

Temperatures at an altitude of approximately 1,500 meters (right chart) are expected to be higher than average, especially over eastern Japan, as the region is likely to be covered by warm air. Conversely, a slight negative deviation is indicated for the Sea of Okhotsk, while in western Japan, Okinawa, and the Amami region, temperatures will remain close to the seasonal average, with the possibility of occasional influence from cold air.



alt=""Image"" width=""500"" height=""281"" /> This forecast covers the expected average temperatures, precipitation, and sunshine duration for the next month, along with weekly average temperature projections (including the probability of occurrence in %).

As the country is likely to be covered by warm air, temperatures over the next month are expected to be above average in Eastern and Western Japan, and near or above average in Northern Japan, Okinawa, and the Amami region.

Due to the anticipated influence of low-pressure systems and fronts-particularly early in the period-precipitation over the next month is expected to be above average along the Pacific coast of Northern Japan and the Sea of Japan side of Eastern Japan. Across the Sea of Japan side of Northern to Western Japan, precipitation is likely to be near or above average. On the Sea of Japan side of Eastern Japan, more cloudy or rainy days than usual are expected.

Sunshine duration over the next month is expected to be below average along the Pacific coast of Northern Japan, and near or below average along the Pacific coast of Eastern to Western Japan. Fewer sunny days than usual are anticipated along the Pacific coast of Northern and Eastern Japan. In Western Japan (Pacific side), while the weather will shift in a cycle every few days, there will likely be fewer sunny days compared to a typical year.

This past week, many areas-especially in Northern Japan-experienced temperatures below average due to the influence of a strong cold air mass. Looking ahead, however, there will be days where temperatures rise above average, particularly across Eastern and Western Japan. That said, cold air may still occasionally push southward, causing temperatures to drop; please adjust your clothing accordingly to stay healthy amidst these temperature fluctuations.

Furthermore, the region is expected to be susceptible to the influence of low-pressure systems and fronts, especially early in the period. Around the 18th-19th, a low-pressure system is forecast to develop rapidly as it moves across the Sea of Japan, which may lead to stronger rain and wind. In Northern Japan, snowfall could also reduce visibility in some areas. Please check the latest weather forecast daily.

Weather forecast for the Chugoku region: Sunshine is expected until tomorrow, the 13th, but the weather will deteriorate from the 14th onwards.

2026/11/12 16:40

"Here is the weather forecast for the Chugoku region.
Today, the area around Japan is under the influence of a high-pressure system.



The Chugoku region has been mostly clear, with plenty of sunshine. There is no risk of rain tonight.



Tomorrow, while some areas may see clouds in the morning, the day is expected to be generally clear. High temperatures will exceed 20C in many places-warmer than the seasonal average.



Looking ahead, a front will approach from the west on Saturday the 14th, leading to a deterioration in the weather. Rain may begin in some areas by the afternoon, and widespread rain is expected on Sunday the 15th.

" />

On Monday the 16th, a winter-type pressure pattern will develop, bringing rain to areas along the Sea of Japan coast.
From Tuesday the 17th through Wednesday the 18th, a low-pressure system accompanied by a front is expected to move across the Sea of Japan while intensifying rapidly, leading to widespread rain once again. Winds will also strengthen, likely resulting in driving, slanted rain. As the front passes, there is a possibility of heavy rain or thunderstorms, so please be sure to check for the latest updates.
On Thursday the 19th, a winter-type pressure pattern will return, bringing rain to the Sea of Japan side of the region. Temperatures are expected to drop significantly, so you will likely need a warm outer layer.
That concludes the weather forecast for the Chugoku region.

Weather for this weekend: Conditions to deteriorate from the west, with rain expected across a wide area on Sunday.

2026/11/12 14:06

This coming weekend, from Saturday the 14th to Sunday the 15th, a weather front and a low-pressure system will approach from the west, causing conditions to deteriorate, starting in Western Japan. If you are planning any outings, Saturday is the better choice.



Today, Thursday the 12th, much of Japan is under the influence of a high-pressure system, resulting in clear skies across many areas. Tomorrow, Friday the 13th, while clouds may develop in some places, the high-pressure system will persist, keeping skies mostly clear.
Looking ahead to the weekend, a weather front and a low-pressure system are expected to approach, leading to a decline in weather conditions, beginning in Western Japan.

On Saturday the 14th, a low-pressure system is expected to form along a front and move eastward. By the afternoon, rain will likely begin to fall in Kyushu, Okinawa, and the Chugoku region.
On Sunday the 15th, the low-pressure system is forecast to travel across the Sea of Japan and pass near Northern Japan. A cold front extending from this system will sweep across much of Honshu, bringing rain to a wide area stretching from the Tohoku region down to Okinawa. Hokkaido is also expected to see an increase in cloud cover.


As a weather front and an area of low pressure pass through, rainfall may intensify in some places. Winds are also likely to pick up, especially along the coast, so you will probably need a sturdy umbrella.
Additionally, warm, moist air will flow toward the front and the low-pressure system, making atmospheric conditions unstable-particularly across the Okinawa and Kyushu regions. Please be on the lookout for lightning, sudden gusts of wind, and intense, short-lived downpours.





Daily high temperatures are expected to be around or above the seasonal average. Even though clouds may spread across the sky, warm air brought in by southerly winds will keep temperatures on the higher side.
Expect highs of around 10C in Hokkaido, over 15C in many parts of the Tohoku region, and around 20C across the Hokuriku, Kanto, and western Japan regions.
Be sure to adjust your clothing appropriately to avoid falling ill due to temperature fluctuations.

From Calm Sunshine to a Dramatic Change: Weekend Rain and Stronger Rain and Winds Expected by Midweek Next Week (Weather Commentary by Meteorologist Junko Miyake)

2026/11/12 13:39

eather conditions will remain sunny through Friday, but rain is expected to spread from the west over the weekend.

First, let's take a look at the current weather distribution.

As of 11:00 a.m. today, many areas across western and eastern Japan, as well as the Pacific side of northern Japan, are enjoying clear skies.

Some rain is falling along the Sea of Japan side of northern Japan, but it is generally light, with rainfall amounts of around 1 to 2 millimeters per hour.

High pressure will continue to cover the region through tonight, bringing mostly sunny weather to much of Honshu.

This high-pressure system extends across the continent, forming an elongated ridge of high pressure.

Sunny conditions are expected to continue across much of Japan through Friday.

However, weather conditions will begin to deteriorate from the west starting Saturday.

A front and low-pressure system will approach from the continent, and rain is expected to gradually begin across Kyushu during Saturday afternoon.

The system will then strengthen somewhat as it moves across Japan with its associated front.

As a result, widespread rain is expected on Sunday, November 15.

Around Tuesday, November 17, a similar pressure pattern to that of Saturday, November 14, is expected to develop, with another front and low-pressure system approaching from the west.

However, the low-pressure system expected next week is forecast to intensify rapidly near Honshu.

Compared to the system affecting Japan this weekend, next week's low is expected to be stronger and may bring heavier rain and stronger winds nationwide.

Please pay close attention to forecasts for rain and wind next week.

Detailed forecasts for each region follow.

For the rest of today, Thursday, sunny weather will continue in many areas.

Temperatures will rise to around 20C during the day, bringing mild and pleasant autumn conditions.

On Friday, although there will be some clouds, generally sunny weather is expected to continue.

Temperatures will rise even higher than today, and from the Kanto region westward, it may be comfortable enough to spend the daytime outdoors wearing just a long-sleeved shirt.

Now for the weekly outlook.

On Saturday, November 14, rain will gradually begin across Kyushu.

As the day progresses, the area of rain will steadily expand eastward.

By Sunday, November 15, widespread rain is expected from Kyushu to the Tohoku region.

Warm southerly winds will accompany the system, meaning that even in Tohoku, precipitation is expected to fall mainly as rain rather than snow.

On Monday, November 16, colder air will move in, and snow is expected in Sapporo.

Wednesday, November 18, a developing low-pressure system may bring stronger rain and winds across the country.

Please continue to monitor the latest weather information.

Typhoon No. 31 transitions into an extratropical cyclone; strong winter-type pressure pattern develops over the vicinity of Honshu during the latter part of the period (Weather Summary: November 1–7, 2026)

2026/11/11 18:51

Summary of weather conditions for the current period (November 1 ? November 7, 2026).

#Weather Summary (November 1 ? November 7)
Average temperatures were generally below normal in Hokkaido and Aomori Prefecture, where the region was frequently affected by strong cold air in the upper atmosphere. From the southern Tohoku region through Kyushu, temperatures tended to be slightly above normal, partly due to the influence of warm air flowing toward low-pressure systems.

Precipitation levels were significantly above normal along the Pacific side of the Tohoku region, in the Kanto region, and near the Izu Islands, driven by factors such as localized fronts, low-pressure systems, and cold northeasterly airflows. In western Japan, precipitation exceeded normal levels in northern Kyushu?an area frequently impacted by low-pressure systems and moist air?with Fukuoka recording a total for the period approximately three times its seasonal average.

Sunshine duration across the region from Hokkaido to Kyushu was generally near or slightly below normal, as weather patterns shifted in cycles every few days. In contrast, the Okinawa and Amami regions experienced minimal impact from low-pressure systems or moist air throughout the period, resulting in sunshine durations significantly above normal.



#Characteristics of Pressure Patterns
On November 1, the area around Honshu was covered by a high-pressure system. New low-pressure systems developed near the northern Korean Peninsula and over central China along a frontal boundary. On November 2, these two low-pressure systems?both associated with fronts?passed through the vicinity of Japan. Meanwhile, Typhoon No. 31 moved west-northwest south of the Ogasawara Islands while maintaining its intensity. By November 3, the low-pressure systems (and their associated fronts) had moved east of Japan, and a "west-high, east-low" pressure pattern (typical of winter-like conditions) developed over the Honshu region. On November 4, the Honshu region was largely covered by a high-pressure system. Typhoon No. 31 moved slowly northward south of Japan before shifting its course toward the northeast and accelerating on the 5th. Near Honshu, a low-pressure system formed along a front in the vicinity of the Izu Islands and moved northeastward. Meanwhile, another low-pressure system developed over the East China Sea along a front extending from Northeast China and South China. On the 6th, Typhoon No. 31 transitioned into an extratropical cyclone east of Japan. Low-pressure systems moving east of the Kuril Islands and across the northern Sea of ??Japan intensified rapidly through the 7th; this led to a strengthening of a "winter-type" pressure pattern (characterized by high pressure to the west and low pressure to the east) over Honshu, causing a surge of cold air to push southward. Far to the south of Japan, a new storm?Typhoon No. 32?formed (the first such occurrence in 32 years).

#Precipitation
On the 1st, the region around Honshu was under the influence of a high-pressure system, with no significant precipitation during the day. Late that night, a heavy rainfall rate of 27.0 mm/h was recorded at Hajikizaki on Sado Island, Niigata Prefecture?a new record for the month of November. On the 2nd, two low-pressure systems accompanied by fronts passed near Honshu, bringing rain across a wide area from northern to western Japan. In the Tohoku and Hokuriku regions, rain persisted even after the fronts had passed. On the 3rd, a shear line associated with Typhoon No. 31 brought periods of moderately heavy rain to Chichijima in the Ogasawara Islands. That evening, localized frontal activity also brought rain to parts of the Sea of ??Japan side of Hokkaido. On the 4th, localized frontal activity near the Izu Islands resulted in a daily rainfall total of 179 mm on Niijima?a new record for November. On the 5th, a low-pressure system along a front brought extremely heavy rain to the Izu Islands; Niijima recorded 202.5 mm of rainfall over a six-hour period, the highest amount ever recorded at that location. On the 6th, a pressure pattern characterized by high pressure to the west and low pressure to the east?accompanied by a strong cold air mass in the upper atmosphere?gradually took shape around Honshu. Through the 7th, cold rain fell across a wide area along the Sea of ??Japan coast, stretching from Northern Japan to the San'in region, while in Hokkaido, the precipitation turned to snow. In Morioka, the first snowfall of the season was recorded on the 7th.

#Temperatures
On the 1st, much of the region from Tohoku to Kyushu was under the influence of a high-pressure system, with daytime temperatures in many areas comparable to those typically seen in mid-to-late October. In Tokonai, Yonaguni Town (Okinawa Prefecture), the temperature reached 30.4C?the only location to record a "midsummer day" (30C or higher) that day. On the 2nd, Northern and Eastern Japan saw little sunshine, and maximum temperatures in many places fell below the seasonal average. In Morioka, the turning of ginkgo leaves to yellow was officially announced. On the 3rd, Honshu was largely covered by a high-pressure system, bringing sunshine to many areas. In Nagoya, the high reached 22.1C?nearly 7C warmer than the previous day. On the 5th, the Kanto region remained cloudy from the morning, preventing temperatures from rising; the high in Tokyo was 16.5C (below average), while in Osaka, it reached 21.1C (near average). Also on the 5th, cold northeasterly winds kept temperatures low along the Pacific coast of the Tohoku region and in Kanto; in Sendai, the high was 13.0C?about 5C lower than the previous day. On the 6th, warm southerly winds blowing toward a low-pressure system caused temperatures to rise across various regions. In Tokyo, the temperature reached 25.3C, marking the first time in three years that a "summer day" (25C or higher) was recorded in November. On the 7th, as a strong cold air mass moved southward, temperatures dropped nationwide. In Sapporo, the daily high was 3.4C, recorded in the early hours of the morning.
