Sunny tomorrow (Sat)—a chance to prepare for winter; weather to deteriorate from the west on Sunday.

2026/10/02 20:21

"Due to a high-pressure system centered near the Asian mainland extending toward Honshu,
sunny skies are expected across a wide area tomorrow, Saturday the 3rd.



While lingering rain or snow is expected in parts of Hokkaido due to a low-pressure system near Sakhalin,
the weather is expected to remain stable across Honshu.



It has been a while since we've had plenty of sunshine over the weekend.
It will be a great opportunity to hang out accumulated laundry
or air out your futons.
However, mornings and evenings are expected to get colder nationwide after the weekend.
We recommend getting your winter bedding ready
or switching to your winter wardrobe this Saturday.



On Sunday, a front moving east from the mainland will cause the weather to deteriorate, starting from the west.
Rain will begin in parts of western Japan, so you will likely need your umbrellas again."

Kanto Heading into a Clear Autumn Weekend: Typhoon No. 27 Strengthens as It Moves North — Ogasawara Islands Urged to Prepare(Commentary by Meteorologist Junko Miyake)

2026/10/02 15:01

Rain fell again today in Tokyo, marking 37 consecutive days with precipitation.
It looks like this long stretch of rainy days will finally come to an end tomorrow.

Tomorrow (Saturday), a high-pressure system is expected to extend from the Asian continent.
Much of the Kanto region will likely see clear autumn skies.
Dry air will cover the area, bringing a crisp and pleasant feel to the weather truly a classic autumn day.

Typhoon No. 27
Now let's take a look at Typhoon No. 27 over the southern seas.
The typhoon is currently near the Mariana Islands, moving westward.
Its maximum sustained winds near the center are 23 m/s, and it is expected to develop a storm-force wind area soon.

By tomorrow (Saturday), it is forecast to strengthen into a "strong" typhoon,
and from Sunday the 4th onward, it is expected to intensify further into a "very strong" typhoon.

On Monday the 5th, the central pressure is projected to drop to 925 hPa.
While maintaining this very strong intensity, the typhoon is expected to approach the Ogasawara Islands quite closely between Monday the 5th and Tuesday the 6th.

After that, on Wednesday the 7th, it is forecast to weaken slightly while moving northward over the sea east of the Kanto region.

Impacts and Warnings
Due to the approaching typhoon, there is already mention of potential warning-level conditions.
In the Ogasawara Islands, waves will begin to rise on Sunday afternoon.
On Monday the 5th, winds will strengthen and storm-force conditions are expected.
By Tuesday the 6th, rain clouds associated with the typhoon's core may bring heavy rainfall.

In the Izu Islands, from Tuesday the 6th through Wednesday the 7th,
and along the Pacific side of the Kanto region on Wednesday the 7th,
waves are also expected to become high.

Since the typhoon will approach the Ogasawara Islands with very strong intensity,
residents should secure any objects that could be blown away over the weekend as part of early preparations.

Weekend Weather in the Kanto Region
On Saturday, many areas will experience clear autumn skies.
It will feel a bit chilly in the morning, so a light jacket will be useful,
but temperatures will rise above 25C in many places during the day a warm, short-sleeve kind of day.

On Sunday, clouds will be more widespread,
but rain is not expected to begin.

Weekly Outlook
At the start of next week, clouds will increase again.
Due to the influence of a front and moist air, unsettled weather is likely to return.
Depending on the typhoon's track, winds may strengthen even in the Kanto region around midweek.

Since the forecast track may change, please continue to check the latest updates.

Typhoon No. 27 Intensifies and Moves NorthPacific Coast May See Stormy Conditions Next Week(Analysis by Meteorologist Junko Miyake) Pacific Coast May See Stormy Conditions Next Week (Analysis by Meteorologist Junko Miyake)

2026/10/02 14:51

Today, the first snowfall of the season has been observed on Mt. Asahidake in Hokkaido.
It truly feels as though winter is beginning to arrive from the northern skies.



Starting this cold season, visual observations by meteorological office staff have been discontinued, and the method has been switched to using analyzed snow depth.
Because of this change, comparisons with the average date of first snowfall or with last year are no longer possible.

Meanwhile, from the Tokai region westward, skies are clear, and many areas are enjoying crisp autumn sunshine.



Through this evening, strong westerly winds will continue across Hokkaido.
Please stay alert for violent winds.
Some areas may also experience rain or thunderstorms.
Snow may continue to fall in the mountains, so drivers crossing mountain passes should be cautious of changing road conditions.



Tomorrow (Saturday), a high-pressure system will extend from the continent.
The strong winds in Hokkaido will gradually ease.
Although westerly winds may remain strong along the Pacific side of northern Japan, many other regions will see calmer conditions.
Widespread autumn sunshine is expected.

In Tokyo, today (Friday) marks the 37th consecutive day with precipitation.
However, tomorrow's clear autumn weather is likely to finally bring an end to this long streak.



Now, here is the latest information on Typhoon No. 27.

As of 9 a.m. today, the typhoon is located near the Mariana Islands and moving westward.
Its maximum sustained winds near the center are 23 m/s, and it is expected to soon develop a storm-force wind area.
The typhoon will continue to intensify as it moves north, becoming strong tomorrow (Saturday).
By Sunday the 4th, it is forecast to become a very strong typhoon, and from Monday the 5th through Tuesday the 6th, it may approach the Ogasawara Islands while maintaining very strong intensity.

After that, it is expected to weaken slightly while moving northward over the ocean east of the Kanto region.

Because the typhoon will approach while still strong, there is an increasing likelihood of warning-level conditions in various areas.



In the Ogasawara Islands, waves are expected to rise from Sunday afternoon.
There is a possibility that storm warnings will be issued from Monday the 5th through Tuesday the 6th.
In the Izu Islands, waves will increase from Tuesday the 6th, and along the Pacific side of the Kanto and Tohoku regions, waves are expected to be high on Wednesday the 7th.
In particular, the Ogasawara Islands may experience violent winds and stormy weather early next week, so please secure any items that could be blown away during the weekend.



Let's look at the weather across Japan.
Tomorrow (Saturday), many areas will see widespread autumn sunshine.
The air will become drier, bringing pleasantly crisp conditions.
In Hokkaido, clouds will be more common during the day, and brief showers may occur through the evening.

On Sunday, a front will approach from the west.
Rain is expected to begin in Kyushu from Sunday evening, and many areas in the Chugoku and Shikoku regions will see rain starting at night.



Here is the weekly forecast.
On Monday the 5th, western Japan will experience widespread rain.
On Tuesday the 6th, a low-pressure system and a front will approach, bringing rain to the Sea of Japan side of northern Japan and the Hokuriku region.

In the middle of next week, the approaching typhoon may strengthen winds along the Pacific side of the Kanto and Tohoku regions, depending on its track.

Latest One-Month Forecast: Sunny Days Expected in October; Warmer Than Average with a Slow Seasonal Progression

2026/10/01 17:54

On Thursday the 1st, the Japan Meteorological Agency released its latest one-month forecast, outlining expected weather conditions for the coming month.



Sea-level pressure near Japan is expected to remain higher than average in the coming period. Consequently, the region is likely to experience relatively frequent days under the influence of high-pressure systems. However, a pressure trough is forecast to form north of Hokkaido; as a result, Northern Japan may be susceptible to the effects of weather fronts and low-pressure systems during the latter half of the period.

Temperatures at an altitude of approximately 1,500 meters are expected to be higher than average across Northern, Eastern, and Western Japan, with the region likely to be covered by warm air.

Weather conditions are expected to fluctuate in cycles lasting a few days. However, there will likely be more sunny days than usual, and precipitation is forecast to be below average, particularly along the Pacific coast. While some areas in the Kanto region experienced record-breaking heavy rainfall in September, October is expected to see a shift toward fewer rainy days.
In Western Japan, continued caution regarding water management is advised for areas currently experiencing water shortages.



Average temperatures are expected to trend higher than normal, suggesting a slow progression of the seasons. Although the leaves on high-altitude mountains across Honshu will begin to change color in the latter half of October, the peak of the autumn foliage season is likely to arrive later than usual.
However, as this is a time of year when significant temperature differences between day and night are common, please be mindful when choosing your daily attire to avoid falling ill. In the Okinawa and Amami regions, surface air temperatures are expected to be high due to the influence of high sea-surface temperatures.

A front is passing through northern Japan; beware of thunderstorms. Cold air is expected to flow in tomorrow, the 2nd, bringing colder temperatures.

2026/10/01 12:09

Today, Thursday, a low-pressure system accompanied by a front is expected to pass through the area stretching from Primorsky Krai to the Strait of Tartary. A cold front will move across Hokkaido and northern Tohoku, causing the area of ??rainfall to gradually shift eastward. Please be alert for sudden thunderstorms.



Rain clouds associated with the cold front currently cover parts of Hokkaido and Aomori Prefecture, bringing heavy downpours to some areas.
In Imakane (Imakane Town, Setana District, Hiyama Region, Hokkaido), 23.5 mm of heavy rain was recorded in the hour leading up to 8:08 AM, setting a new record for the highest hourly rainfall for October in that location.



The rain clouds are expected to move gradually eastward from here on. As the cold front passes, some areas may experience localized heavy rain accompanied by thunder. Please be cautious of lightning strikes and sudden gusts of wind.



The low-pressure system is forecast to intensify as it moves into the Sea of ??Okhotsk by tomorrow, Friday. The pressure gradient around Hokkaido will steepen, leading to stronger winds; please be on the alert for strong winds and high waves.

Additionally, cold air is expected to flow into the upper atmosphere as the front passes. Tomorrow, Friday the 2nd, clouds will likely spread across Northern Japan?particularly along the Sea of ??Japan coast?bringing rain to some areas. Some mountainous regions might even see their first snowfall of the season.
Temperatures will drop compared to today, Thursday the 1st; highs are forecast to reach 14C in Asahikawa and 18C ??in Sapporo. With lows hovering around 10C, it will feel chilly in many places. Please adjust your clothing accordingly and take care to stay healthy.

2026/10/01 06:25

As we begin October today (Thursday), a front is expected to pass near Northern Japan. Additionally, Typhoon No. 26 is forecast to pass near Aogashima and move away to the east of Japan.



In Northern Japan, the area of ??rainfall is expected to shift across the region.
Rain is likely on the Sea of ??Japan side of Hokkaido until around midday, while the northern Tohoku region and the Pacific side of Hokkaido will see rain starting in the early afternoon. Some areas may experience heavy rain accompanied by thunder, so please be cautious of lightning strikes and sudden gusts of wind. It is advisable to carry rain gear when going out. Please also be mindful of temperature changes, as colder air will flow in after the front passes.

While many areas along the Sea of ??Japan?stretching from southern Tohoku and Hokuriku to the Chugoku region?will see sunny skies, there is a possibility of passing showers in the afternoon, so carrying a folding umbrella is recommended.

In the Kanto region, scattered showers are likely, mainly in southern areas, until the morning.
Conditions are expected to improve in many areas by the afternoon. Temperatures will rise in many places compared to yesterday, so please take care of your health.

From the Tokai region through Western Japan, sunny skies are expected to prevail throughout the day. Temperatures will reach around 30C in many areas, creating conditions where you might break a sweat if active; please take precautions against heatstroke.
