The autumn rain front is heading north again, and there is a risk of heavy rain in Kyushu and Tohoku from tomorrow 6th (Sunday) to 8th (Tuesday)

2026/09/05 22:48

Typhoon No. 24 will head south of Okinawa until the 6th (Sunday), then make a U-turn and slowly move northward near the Nansei Islands until the evening of the 7th (Monday), gradually turning into a tropical cyclone. Additionally, another tropical cyclone south of Japan is expected to continue moving north.



Additionally, the front that is stationary near the southern coast of Honshu is expected to remain mostly stationary until the 6th (Sunday), and gradually move northward on the 7th (Monday). Warm, moist air from around typhoons and tropical cyclones will flow toward the front, making the front very active.



Extremely heavy rain accompanied by thunder and lightning will fall on the Pacific coast of Okinawa, Amami, Kyushu and Tohoku into the 7th (Monday), with the risk of warning-level heavy rain.




After that, the total rainfall may increase until the 8th (Tuesday) depending on the path of the typhoon (or tropical cyclone) and the movement of the front.

The expected precipitation is as follows:

[Rain Forecast]

in the Tohoku region, and 80mm

in the Tohoku region.

There will be heavy rain in some places, mainly on the Pacific side of eastern Japan, such as the Kanto and Tokai regions, from the 7th (Monday) to the 8th (Tuesday), exceeding the average rainfall in a single month in September. Please be extremely careful about landslides, flooding of low-lying land, flooding of roads, and rising river waters.

The autumn rain front is expected to slowly move northward, with heavy rain at warning level expected to peak around the 7th in wide areas of western and eastern Japan.

2026/09/05 14:02

The autumn rain front is stationary in the south of Honshu, and Typhoon No. 24 is heading south in the East China Sea with late warnings.
There is a tropical cyclone in the south of Japan, and it is expected to move northward at a faster pace as it approaches the autumn rain front.
The autumn rain front, which has been stationary south of Honshu due to the influence of the tropical cyclone moving northward, is expected to move northward little by little from around the 6th to the 7th.



For this reason, heavy or very heavy rain with thunder is expected to occur in some places, mainly on the Pacific side of western and eastern Japan. Tomorrow, on the 6th, it will gradually rain in western Japan and the Pacific side of eastern Japan, and on the 7th, heavy rain is expected, especially on the Pacific side of eastern Japan. The area of rain is expected to gradually spread to the Tohoku region.



As of noon today, the 5th (Saturday), the forecast is that the peak of the rain will be from the night of the 6th (Sunday) to the middle of the morning on the 7th (Monday). In particular, heavy rain is expected in the Pacific side of eastern Japan, including the Kanto and Tokai regions, and it is likely that the timing of the heavy rain will coincide with commuting hours. There is a risk of heavy rain reaching a warning level, including in plains and urban areas.

Also, depending on the trends of the autumn rain front, Typhoon No. 24, and tropical cyclones, rain may continue after the 9th, and the total rainfall may increase further.



Past heavy rains have loosened the ground in some areas, making landslides more likely to occur even with the slightest amount of rain.Be wary of landslides, and be careful of inundation of low-lying areas and rising or overflowing rivers.
Also, please be aware of the impact of heavy rain on transportation, and be sure to check the latest weather information and typhoon information that will be updated in the future.

Record-breaking heavy rain in Yakushima, Kagoshima Prefecture; strict vigilance continues for landslides, river rises and flooding

2026/09/05 12:34

Today, the 5th (Saturday), Typhoon No. 24 is moving slowly in the East China Sea, and the autumn rain front is stationary south of Honshu. Additionally, a tropical cyclone is heading north to the south of Honshu.
Warm, humid air from typhoons and tropical cyclones is flowing toward the autumn rain front, and some places in southern Kyushu are experiencing record-breaking heavy rain.

In Yakushima, Kagoshima Prefecture, rain continued to fall due to Typhoon No. 24 and the stationary autumn rain front, and linear precipitation bands formed one after another late at night on the 4th the previous day and early in the morning on the 5th today. In Onoma, where the AMeDAS rain gauge is located, 485.5 mm of precipitation was observed in the 24 hours up to 11 a.m. on the 5th (approximately 1.7 times the normal precipitation in September), and as of 11 a.m. on the 5th, the AMeDAS rain gauge in Yakushima had recorded 423.0 mm, which is equivalent to 450.7 mm of precipitation for one month in September. Although it is a region with a lot of rain, more rainfall fell in one day than the average amount of rainfall in September in one month.

Due to this heavy rain, a temporary level 5 heavy rain special warning (switched to a warning around 7:50 a.m.) and landslide special warning were announced for Yakushima Town, Kagoshima Prefecture, just after 5 a.m. today, Saturday, the 5th.
(*At around 11:30 a.m. on the 5th, the special landslide warning changed to "landslide danger warning" and the heavy rain warning changed to level 2 "heavy rain advisory.")



Typhoon No. 24 is expected to move southward in the East China Sea, and the autumn rain front is expected to remain stationary south of Honshu. It is expected that moist air from typhoons and tropical cyclones will continue to flow toward the front. In southern Kyushu, it will continue to rain intermittently even after today, and in some places it will be heavy rain accompanied by thunder. There is a risk that the rain will continue and the total amount of rainfall will increase further.



The ground has already become loose in some places due to heavy rain, and even a small amount of rain could cause landslides. Please continue to be extremely cautious of landslides. Also, please avoid approaching dangerous slopes and flooded rivers.

Weather for the week: Next week will be a week of many cloudy and rainy days, with the autumn rain front taking center stage. Widespread risk of warning-level heavy rain on the 7th.

2026/09/05 12:30

Near Japan, the autumn rain front is likely to stay near Honshu into next week, and there will be many cloudy and rainy days over a wide area.



As of 9 o'clock, Typhoon No. 24 is heading south north of Kumejima, and the autumn rain front is extending from southern Kyushu to the southern coast of Honshu.



The typhoon is expected to move south until tomorrow the 6th (Sunday) and pass near the Nansei Islands. There is a risk that it will then change course from east to north in the south of Japan and move north toward Japan. Additionally, there is a tropical cyclone in the south of Japan, which is expected to move northward to the south of Honshu into tomorrow, the 6th (Sunday). As typhoons and tropical cyclones move northward, a front that has stalled near the southern coast of Honshu will slowly move northward from tomorrow 6th (Sunday) to 7th (Monday), and is expected to stall near Honshu next week.



Looking at the weekly weather forecast, there are many cloudy and rainy days across the country due to the influence of the autumn rain front, so it looks like it will be a week when umbrellas will be useful.
Rain clouds are likely to develop especially on the Pacific side, and there is a risk of widespread warning-level heavy rain on the 7th (Monday). In areas such as Hokuriku and southern Kyushu, where the ground has become loose due to heavy rains, even a small amount of rainfall could increase the risk of landslides. Please be careful of landslides and rising river waters.
Even after the 8th (Tuesday), it will be susceptible to the effects of autumn rain fronts and low pressure systems, and total rainfall may increase mainly from the Pacific side of eastern to western Japan. Be aware of disasters caused by long rains and prepare early by cleaning gutters and checking hazard maps.

Weather for today, the 5th (Saturday): Heavy rain warning for southern Kyushu to Okinawa

2026/09/05 06:04

The autumn rain front is expected to stay on the southern coast of western and eastern Japan. Rain will fall mainly on the Pacific side and the Kanto region. Southern Kyushu, which has already experienced heavy rain, needs to be on guard against landslides and flooding. Northern Japan, which is covered by high pressure, will have many areas where the sun will reach.



The autumn rain front will move further south and the rainy area will be smaller than yesterday, but it looks like it will be a rainy day on the Pacific side. Due to the continuous flow of warm and humid air from Typhoon No. 24, there is a risk of heavy rain from southern Kyushu to Okinawa. We need to be on guard against landslides, rising and flooding rivers, and flooding of low-lying land.
Although there are many clouds on the Sea of Japan side, there are few places where it rains, and you can expect to see occasional sunny spells. It will be hot and humid during the day as the sun shines through.
The weather in the Kanto region is likely to be dull throughout the day. Widespread rain is possible in the morning, with occasional showers possible in the afternoon. Please take an umbrella with you when you go out.
Northern Japan will be covered in high pressure and will have many sunny days. The morning is chilly and it feels like autumn. During the day, the sun will shine and the temperature will rise, and the daily temperature difference is expected to increase. Please adjust your clothes appropriately.

National weekly weather from 9/5 (Sat) to 9/11 (Fri)

2026/09/04 20:10

Due to Typhoon No. 24 and the autumn rain front, it looks like it will be a week of widespread rain. In some places, such as Hokuriku and southern Kyushu, the ground has become loose due to previous rains, so please be on guard for new disasters. Additionally, the heat is expected to subside in eastern and western Japan, giving it a bit of an autumn feel.



The autumn rain front is expected to continue moving north and south and remain near Honshu. It will continue to be rainy mainly in western and eastern Japan.
Until around the 7th (Monday), moist, warm air from Typhoon No. 24 will flow into the front, causing heavy rain, especially on the Pacific side. Additionally, a low pressure system is expected to form or pass over the front, and there is a risk of heavy rain in the Kanto region as well.
There are places in Hokuriku and southern Kyushu that have experienced heavy rains, where the ground is loose, so you need to be especially careful about landslides, flooding of low-lying areas, and rising river waters.
Typhoon No.24 is wandering around the Nansei Islands. Okinawa and Amami, which are close to typhoons, should be on guard for heavy rain, strong winds, and high waves over the weekend. Typhoon No. 24 is expected to turn into a tropical cyclone around the 8th (Tuesday).
As the autumn rain front moves southward, it looks like autumn will be felt to the north of the front. There will be no severe residual heat next week, and the maximum temperature is expected to be around 30c in both eastern and western Japan.
The location of the front and the path of the typhoon are subject to change, so please check the latest information.

Latest 1-month forecast: Severe summer heat continues into late September, with precipitation expected to increase on the Pacific side of western Japan and Kanto-Koshinetsu

2026/09/04 19:41

On the 3rd (Thursday), the Japan Meteorological Agency announced the latest monthly weather forecast for the coming month.
Temperatures are expected to be higher than average across the country, and the severe summer heat is likely to continue.



According to the results of the Japan Meteorological Agency's numerical forecast model, the high pressure is expected to be strong over the sea east of Japan, while the area near Japan is predicted to have a trough in pressure.
From northern to western Japan, warm, humid air around the high pressure will enter during the first half of the period, making it susceptible to the effects of an active autumn rain front.



Okinawa/Amami will be susceptible to the effects of typhoons and humid air, especially at the beginning of the season. In the latter half of the period, the high pressure near central China will likely cover western Japan and Okinawa/Amami.

Precipitation is expected to be higher than normal on the Pacific side of western Japan and in the Kanto-Koshinetsu region.When the autumn rain front is stationary and affected by cold and moist air in the upper atmosphere, localized heavy rain like guerrilla thunderstorms may occur.Pay attention to how the rain falls.This is also the time when typhoons tend to approach Honshu, so typhoon forecasts are announced. If you are planning to visit Japan, be sure to check the latest information.

The weather in the future will be cyclical in northern and eastern Japan, typical of this time of year.In western Japan, the weather will change every few days, but the first half of the period is expected to have fewer sunny days than normal, and the second half is expected to have more sunny days than normal. In Okinawa/Amami, it is predicted that the first half of the period will have fewer sunny days than normal years, and the second half of the period will have more sunny days than normal years.

[Typhoon + Stagnant front = Prolonged heavy rain] Warning-level heavy rain likely to continue into next week (Commentary: Weather forecaster Atsuko Miyake)

2026/09/04 13:57

From now until next week, heavy rain is expected to continue for a long time due to slow-moving typhoons and fronts.

Please be careful of landslides and other disasters, and transportation may be affected, so please pay attention to the latest information.



This is the weather map from today's 4th (Friday) to tomorrow 5th (Saturday).

There is almost no movement of the front into tomorrow, the 5th (Saturday). The
front is expected to remain active as typhoons and tropical cyclones bring moist air from the south.

The pressure distribution of a typhoon in the south and a stationary front near Honshu is a typical pressure distribution pattern that will lead to heavy rain.
As this situation continues for a long time into next week,
there is a possibility that heavy rain will continue for a long time in similar places.



Rain clouds are forecast for tomorrow (Sat).

Rain clouds associated with the typhoon and front are expected to cover a wide area from the Nansei Islands to western and eastern Japan.
There are some areas where it rains very heavily, exceeding 50mm per hour, and
In western Japan, there are some places where it rains exceeding 80mm per hour.



It will continue to rain in similar places into tomorrow (Sat).

The front is expected to move southward a little tomorrow, but
there is a risk of continued heavy rain in Miyazaki Prefecture, where the humid air surrounding the typhoon flows,
as well as Kochi on the Pacific side of Shikoku, Wakayama and Mie Prefectures on the Kii Peninsula,
.

There is a possibility that a linear precipitation belt may occur, especially from Kyushu to Shikoku and the Amami region.
If a linear precipitation belt occurs, the risk of heavy rain disasters will increase immediately.



Let's take a look at the expected amount of rain.

The expected amount of rain by tomorrow (Saturday) morning is
300 mm in Shikoku and 250 mm in southern Kyushu.
After that, heavy rain of 100mm to 200mm is expected to continue into Monday.
The total amount for the past three days is expected to be 650 mm in Shikoku.
There is a risk that around twice as much rain will fall in a month at this time of year.

The effects of long-lasting heavy rains include landslides, river flooding, flooding of houses, and flooding of roads.
Also, please be aware of the impact on transportation such as Shinkansen and airplanes.



This is the weather in various places from now on.

On Saturdays and Sundays, rain marks will be noticeable mainly in western and eastern Japan.
There are likely to be some places where heavy or extremely heavy rain will fall, especially on the Pacific side.
Please be careful of heavy rain.

In areas west of the Tokai region, temperatures will rise to around 30c, and the hot and humid conditions will continue.
Even if it is not an extremely hot day, the humidity is high, so
Please continue to be careful of heat stroke.

In Hokkaido and Hokuriku, there will be many sunny days on Saturdays and Sundays
The temperature will rise to 28c in Sapporo on the 6th (Sunday).
The sun seems to be shining brightly.



From now on, the front will remain mostly stationary near Honshu into next week.
Warm, moist air continues to flow toward this front from the south.
As long as this situation continues, it will continue to be rainy.



Looking at the weekly forecast,
it will continue to rain around Honshu for a long time into next week.
In particular, there is a risk that warning-level heavy rain will continue for a long time until around the 9th (Wednesday).
Please continue to pay close attention to the latest information.

Typhoon No. 24's path becomes complicated around Okinawa; the autumn rain front stagnates near Honshu, prolonging the effects of heavy rain

2026/09/04 13:09

Today, the 4th (Friday), Typhoon No. 24 is moving northwest of Amami City. The typhoon is moving slowly, and the warm, humid air flowing around the typhoon is activating the autumn rain front that has stalled on the southern coast of Honshu.

#Typhoon No. 24 Friday the 4th, as of noon
==================
Center location Approximately 220km northwest of Amami City
Traveling speed north-northwest 10km/h
Central pressure 992hPa
Maximum wind speed 18m/s (near the center)
Maximum instantaneous wind speed 25m/s
==================



Typhoon No. 24 is expected to change its course to the south and take an easterly course around the 6th. It is moving in a complicated manner, moving counterclockwise around Okinawa and Amami, and the current forecast is that it will turn into a tropical cyclone in the south of Japan around the 8th.

In addition to the slow movement of the typhoon, the autumn rain front is expected to remain stationary near Honshu for some time to come. Additionally, there is another tropical cyclone in the south of Japan, which may move northward little by little.
As a result of these effects, warm, humid air will continue to flow toward the autumn rain front, and heavy rain is expected to continue from western Japan to the Pacific side of eastern Japan.



Also, just after noon today, Friday the 4th, the Japan Meteorological Agency announced the "Meteorological Disaster Prevention Bulletin (Linear Precipitation Zone Immediate Forecast)" for Miyazaki Prefecture. There is a risk that a linear precipitation band will form over the next three hours in the plains and mountainous areas of southern Miyazaki Prefecture, and very heavy rain will continue to fall in similar areas.
When a linear rain belt occurs, the risk of serious landslides, flooding, and river flooding that can be life-threatening increases rapidly.



Please continue to be extremely cautious of landslides caused by heavy rain, flooding of low-lying areas, and rising and flooding rivers.
Heavy rain will continue in the Pacific Ocean region from Kanto to southern Kyushu until around the 7th, and depending on the trends of the typhoon and front, there is a risk that the total amount of rainfall will increase further in the future.
Please pay attention to the latest weather information and typhoon information that will be updated in the future, as well as evacuation information announced by local governments.
