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.

Tropical Storm "Pena" southwest of the Hawaiian Islands: Could it become the second cross-basin storm of the year?

2026/11/11 16:29

Today, Wednesday the 11th, the powerful Typhoon No. 32 has moved out over the waters east of the Ogasawara Islands and is expected to continue moving further away from Japan. By tomorrow, the 12th, it is forecast to transition into an extratropical cyclone over the open ocean far to the east of Japan.
Although the Ogasawara Islands are no longer within the typhoon's strong-wind zone, rough sea conditions?with wave heights of 4 to 5 meters?are still expected tomorrow, Thursday the 12th. Residents in the Ogasawara region should remain cautious of high waves through around the 12th.

Meanwhile, far to the east of Japan?southwest of Hawaii - a tropical disturbance named Tropical Storm "Pena" has been identified.
As of 9:00 p.m. local time on the 10th, Tropical Storm "Pena" had a central pressure of 1002 hPa and maximum sustained winds of 20 m/s near its center; it is currently moving westward at a slow pace.
It is expected to continue on a westward path, crossing the 180th meridian (180E) around the 14th (Japan Standard Time) and entering the monitoring area of ??the Japan Meteorological Agency (JMA). Should "Pena" cross the 180th meridian without losing its current intensity, it will be designated and numbered as a "typhoon."



In 2026, the number of typhoons formed so far has already exceeded the annual average.
It is a rare phenomenon?occurring only about once every few years?for a tropical cyclone that forms east of the 180th meridian to cross that line and enter the Japan Meteorological Agency's monitoring area; such storms are known as "cross-boundary typhoons." However, in 2026, there has already been one instance of a "cross-boundary" typhoon-Typhoon 28, "Nolo"?which crossed the 180th meridian on October 5th. If "Pena" also crosses this boundary, it would mark the second such occurrence this year.



Current forecasts suggest that Tropical Storm "Pena" may weaken slightly around the time it crosses the 180th meridian on or about the 14th, making it uncertain whether it will officially qualify as a "cross-boundary typhoon." To be classified as a "typhoon," the maximum sustained wind speed near the center must be approximately 17.2 m/s or greater at the time it crosses the boundary.
Even if it were to become a "cross-boundary typhoon," it is sufficiently far from Japan that it is unlikely to have any impact on the weather in the vicinity of Japan thereafter.

Weekly Weather: Large temperature differences between day and night expected through this weekend; widespread rain likely on Sunday the 15th due to a low-pressure system.

2026/11/11 14:47

Through this weekend?around Saturday, the 14th?much of the area around Honshu will be under the influence of a high-pressure system. Most regions will see clear, stable weather, making it a great time for drying laundry.
However, mornings will be quite cold. Tomorrow, Thursday the 12th, temperatures in northern Japan will hover around 0C, with some inland areas dropping below freezing. Across western and eastern Japan, temperatures will widely fall below 10C; through Saturday the 14th, many areas in these regions will see morning temperatures around 10C. With significant temperature differences between day and night, please take care to stay in good health.



Around Saturday the 14th, the high-pressure system will shift east of Japan, while a low-pressure system approaches from the west. Conditions will begin to deteriorate from the west, and by Sunday the 15th, rain is expected across many regions.
As the new week begins on Monday the 16th, the weather will improve in many areas along the Pacific coast of western and eastern Japan. Meanwhile, in the regions along the Sea of ??Japan?from northern Japan through the Hokuriku and San'in areas?cold air aloft will bring chilly rain, with snow expected in Hokkaido.

Around Tuesday the 17th, a new, intensifying low-pressure system is expected to move across the Sea of ??Japan. Another low-pressure system is also forecast to form along the Pacific side, likely leading to widespread unsettled weather across the Pacific-facing regions of western and eastern Japan. Along the Sea of ??Japan, rain and snow are expected, particularly in northern Japan. From northern Japan through the Hokuriku region (along the Sea of ??Japan), conditions may become rough with strengthening winds through Wednesday the 18th; please stay updated with the latest weather information.

Impact of Typhoon 31 in the first half; winter-type pressure pattern in the latter half [Marine Summary: November 1–7, 2026]

2026/11/11 13:25

Typhoon No. 31 moved westward across the waters south of Japan, then shifted to an eastward path from the 5th onward. Near the center of the typhoon, conditions became severely rough, with wave heights exceeding 6 meters.

Below is a summary of marine conditions (November 1 - November 7, 2026).



Pressure Patterns and Waves
On the 1st, due to a low-pressure system over the Sea of ??Okhotsk, wave heights in the northern Sea of ??Japan reached 3 meters or more. From the 1st to the 6th, Typhoon No. 31 moved westward, then shifted eastward starting on the 5th. Near the typhoon's center, conditions became severely rough with wave heights exceeding 6 meters; meanwhile, on the 5th, waves along the Pacific coast of Honshu also rose to 3-4 meters. On the 6th, a ""winter-type"" pressure pattern gradually developed around Japan, leading to a steeper pressure gradient near Honshu. Rough conditions emerged in the Sea of ??Japan, with wave heights exceeding 4 meters. By the 7th, a strong winter-type pressure pattern had taken hold, resulting in severely rough seas across a wide area of ??the Sea of ??Japan, with wave heights exceeding 6 meters. Rough conditions-with waves reaching approximately 5-6 meters-were also observed off the coast of Abashiri and in the waters east of Hokkaido.

Sea Surface Temperature
In the waters north of Japan, the area where temperatures were significantly higher than average has shrunk, though temperatures remain above average across a broad region; in the western Sea of ??Japan, they were up to 3C higher than normal. In the southern East China Sea, the area with significantly above-average temperatures has also decreased. Southeast of the Kanto region, the area with significantly higher-than-average temperatures has contracted, yet temperatures remain above average over a wide area. Temperatures were up to 3C higher than average off the southeastern coast of Hokkaido, and up to 4C higher east of the Kanto region. Near the Kuril Islands and in the Sea of ??Okhotsk, the area with slightly above-average temperatures has shrunk, while the area with below-average temperatures has expanded.


Ocean Current Forecast
The Kuroshio Current will flow away from the coast along the eastern shore of Kyushu and off Cape Ashizuri, while it will flow close to the coast off Cape Muroto. Off Cape Shionomisaki, it will continue to flow close to the shore. After flowing eastward off Cape Shionomisaki, the southernmost point of the current off the Tokai region will be near 33N, 140E. Near the Izu Islands, the current will pass in the vicinity of Hachijo Island. Off the Boso Peninsula, the current will alternate between flowing away from and toward the coast. The southernmost extent of the Oyashio Current remains retracted to the east of 148E. The area covered by the Oyashio Current is significantly smaller than average. The strength of the Tsushima Warm Current is significantly greater than average.

Weather Forecast for the Tohoku Region: Beware of Morning Chills and Large Temperature Fluctuations

2026/11/11 13:01

Here is the weather forecast for the Tohoku region for today, Wednesday the 11th, and tomorrow, Thursday the 12th.



Today, Wednesday the 11th, much of Honshu is under the influence of a high-pressure system. In Northern Japan?specifically in Hokkaido and along the Sea of ??Japan side of the Tohoku region?some areas are experiencing snow or rain.



In the Tohoku region today, the Sea of ??Japan side will be mostly cloudy with localized snow or rain, though conditions will clear up in many places by the afternoon. On the Pacific side, the weather will be calm and sunny.



Tomorrow, Thursday the 12th, the Tohoku region will continue to be largely under the influence of a high-pressure system. It will be sunny during the day, especially on the Pacific side; however, morning temperatures will drop to around 0C with some inland areas falling below freezing. Please be mindful of the significant temperature difference between the morning and the daytime, and take care of your health.



Looking ahead, around the 15th, rain is expected, primarily along the Sea of ??Japan side.
That concludes the weather forecast for the Tohoku region.

Sunday the 15th is Shichi-Go-San—what’s the weather looking like for the weekend?

2026/11/11 08:53

This Sunday, the 15th, is Shichi-Go-San?a special day to celebrate the healthy growth of children and grandchildren. Many families may be planning to visit a shrine or temple for prayers.
If you are planning an outing, be sure to check the weather forecast for this weekend.

Weather for Saturday, the 14th
On Saturday, the 14th, high pressure is expected to cover areas from Eastern to Northern Japan. Much of the Kanto-Koshin region and the Pacific-facing side of Northern Japan will see clear skies, making it a great day for going out. In contrast, Western Japan and regions along the Sea of ??Japan are likely to be mostly cloudy due to the influence of moist air; northern Kyushu may even see some rain at times.
High temperatures across Eastern and Western Japan will be around 20C, making for a comfortable day. However, low temperatures in Eastern and Northern Japan will drop into the single digits?please be prepared for chilly conditions in the morning and evening.





Weather for Sunday, the 15th
On Sunday, the 15th?the day of Shichi-Go-San?a low-pressure system will move from the Sea of ??Japan toward the east of Japan, likely bringing unsettled weather across the country. While Hokkaido is expected to be cloudy, rain is forecast for most other regions, making for rather unfortunate weather for Shichi-Go-San shrine visits. If you are heading out in a kimono or formal attire, please take extra care regarding your footing and protection against the rain.

[Typhoon Information] Typhoon No. 32 has passed the Ogasawara Islands and is expected to move further away to the east of Japan.

2026/11/11 07:22

As of 6:00 a.m. today, Wednesday the 11th, Typhoon No. 32 (Champaka) is moving east-northeast at a speed of 45 km/h. It is currently located east of Chichijima Island and is maintaining a strong intensity.

Typhoon No. 32 - Wednesday, the 11th, 6:00 a.m.
------------------------------------
Center Location: East of Chichijima Island
Size: -
Intensity: -
Movement: East-northeast at 45 km/h
Central Pressure: 975 hPa
Maximum Sustained Wind Speed: 35 m/s (near the center)
Maximum Instantaneous Wind Speed: 50 m/s
------------------------------------




On Chichijima Island in the Ogasawara chain, a maximum instantaneous wind speed of 22.6 m/s was recorded as of 6:00 a.m. today, Wednesday the 11th, indicating that winds are intensifying. It is possible that even stronger winds are occurring on Hahajima Island, which is closer to the center of the typhoon.
Although the storm warning previously issued for the Ogasawara Islands was lifted early this morning (Wednesday, the 11th), a strong wind advisory remains in effect; caution regarding high winds is advised throughout the remainder of the day.

Outlook
Typhoon No. 32 is expected to move further away to the east of Japan and transition into an extratropical cyclone far to the east of the country by tomorrow, Thursday the 12th.
Even after it becomes an extratropical cyclone, the pressure gradient between it and a migratory high-pressure system over Honshu will increase. This may lead to continued high waves in the waters east of Japan, so please remain cautious and alert to the risk of high waves.

[Weekly Weather] Mostly sunny from tomorrow, the 11th, onwards; rain expected across a wide area around the 15th.

2026/11/10 17:26

Here is the weather forecast for the coming week.
Today, Tuesday the 10th, clouds spread across a wide area, with rain or snow falling in many places-primarily during the morning. However, the region is gradually coming under the influence of a high-pressure system extending from the Asian continent, and the weather is beginning to clear, starting from western Japan.

Tomorrow, Wednesday the 11th, the area around Japan will increasingly fall under the influence of this high-pressure system, bringing clear skies to many locations.
Generally fair weather is expected to continue through around Saturday the 14th. From around Sunday the 15th, however, the passage of a low-pressure system and a front is likely to cause a deterioration in weather conditions nationwide.



Tomorrow, Wednesday the 11th, the region around Japan will come under the influence of a high-pressure system. While some areas along the Sea of ??Japan-from Hokkaido through the Tohoku region and into the Hokuriku region-may see lingering rain or snow during the morning, the overall trend is toward clearing skies. Although snow may continue into the afternoon in parts of northern Hokkaido, most other areas will be generally clear, providing a good opportunity to hang laundry outside.

Meanwhile, in the Ogasawara Islands, Typhoon No. 32 is expected to make its closest approach between tonight and the early hours of Wednesday the 11th, bringing rough weather. Please exercise extreme caution regarding violent winds late tonight, and remain alert for potential landslides caused by heavy rain through the morning of Wednesday the 11th.
At sea, conditions are expected to become very rough with swells. Please remain on high alert for high waves accompanied by swells through the evening of Wednesday the 11th.



From the day after tomorrow, the 12th (Thursday), through the 13th (Friday), the area around Honshu is expected to be under the influence of a high-pressure system. While clouds may spread across parts of the Sea of ??Japan side on the 13th (Friday), other areas will likely see sunny intervals.

On the 14th (Saturday), a low-pressure system will approach from the west, and the weather in Kyushu is expected to deteriorate. Most other regions will remain generally sunny.

On the 15th (Sunday), a low-pressure system accompanied by a front is expected to move eastward across Japan. Clouds will spread nationwide, and rain is likely. Near the front and the low-pressure system, rainfall may intensify, and winds could also pick up; you will definitely need a sturdy umbrella.

On the 16th (Monday), following the passage of the low-pressure system, a "west-high, east-low" pressure pattern will develop, bringing rain or snow to the Sea of ??Japan side.

On the 17th (Tuesday), another low-pressure system will move eastward from the Sea of ??Japan, bringing widespread rain or snow.

Since the weather is likely to become unstable during the latter part of this period, it is recommended that you complete tasks such as hanging laundry outside, finishing any seasonal clothing changes, or planning outings during the first half of the period.




For the coming week, daily high temperatures will generally be around or above the seasonal average.
Today, Tuesday the 10th, saw temperatures typical of December in northern Japan-due to an influx of cold air-and in the Kanto region, where cold rain fell. However, temperatures are expected to rise again, particularly on days with clear skies.
Please note that on clear days, there will be a significant difference in temperature between the daytime and the morning or evening hours. Be mindful when choosing your attire; it is advisable to wear layers-such as a warm jacket or an outer garment-that can be easily put on or taken off.

The weather will improve today, the 10th; tomorrow, the 11th, much of the region is expected to be sunny as a high-pressure system moves in.

2026/11/10 15:19

Here is the weather forecast for Japan.
Currently, a very strong Typhoon No. 32 is moving eastward to the south of Japan, with a frontal line extending to its north.
Meanwhile, a high-pressure system is extending from the Asian continent, creating a pressure pattern characterized by higher pressure to the west and lower pressure to the east across Japan.

At present, rain or snow is falling in parts of the Hokuriku region and along the Sea of ??Japan side of Hokkaido and the Tohoku region. Rain is also occurring in the southern Kanto region and Shizuoka Prefecture. In western Japan-excluding Kyushu-much of the area is covered by clouds.



As a high-pressure system gradually moves over the region, the weather is expected to improve. Rain in the southern Kanto region and Shizuoka Prefecture is forecast to taper off by this evening, so please remember to take your umbrella with you when you head home.
However, rain or snow may continue in parts of the Hokuriku region and along the Sea of ??Japan side of Hokkaido and the Tohoku region through tomorrow, Wednesday the 11th.

In the Ogasawara Islands, Typhoon No. 32 is expected to make its closest approach between tonight and the early hours of tomorrow, Wednesday the 11th, bringing rough weather. Please remain on high alert for violent winds late tonight, and stay cautious regarding the risk of landslides caused by heavy rain through the morning of Wednesday the 11th.
At sea, conditions are expected to become very rough with swells. Please exercise caution regarding high waves accompanied by swells through the evening of Wednesday the 11th.

/>

Tomorrow, Wednesday the 11th, the area around Honshu is expected to be under the influence of a high-pressure system.
During the morning, some areas along the Sea of ??Japan-from Hokkaido through the Tohoku region and into the Hokuriku region-may see rain or snow. In the northern part of Hokkaido, snow may continue into the afternoon. Elsewhere, however, it will generally be sunny, making it a good opportunity to hang laundry outside.
Daily high temperatures will be higher than today's in many places, reaching levels typical for this time of year.



Looking ahead, the weather is expected to be mostly sunny as the region remains under the influence of high pressure. However, on Sunday the 15th and Tuesday the 17th, low-pressure systems and fronts will pass over Japan, likely bringing rain or snow across the country.



On sunny days, there will be a significant temperature difference between the morning/evening and the daytime. Please choose your clothing carefully-consider wearing a warm outer layer or items that are easy to put on and take off.

Additionally, the weather forecast for the Kanto region is also available in a video presented by an AI weather caster; please take a look.
