[Latest Typhoon Information] Typhoon No. 26 is forecast to move northward while intensifying; it is expected to slow down near Okinawa, raising concerns of prolonged impact.

2026/09/26 07:16

As of today, Saturday the 26th, Typhoon No. 26 is moving in a northerly direction over the waters south of Okinawa.

# Typhoon No. 26 ? As of 6:00 AM, Saturday the 26th
====================================
Center location: South of Okinawa
Movement speed: North-northwest at 10 km/h
Central pressure: 996 hPa
Maximum sustained wind speed: 25 m/s (near the center)
Maximum instantaneous wind speed: 35 m/s
====================================



Typhoon No. 26 is expected to move northward while maintaining a gale-force wind zone. By tomorrow, Sunday the 27th, it is forecast to intensify into a "strong" typhoon, with maximum sustained winds near the center reaching 35 m/s or higher.
From the 27th onwards, the storm is expected to gradually shift its course toward the east; due to its slow movement, there is a risk of prolonged impacts in the Okinawa and Amami regions. Starting today, the 26th, coastal waves will gradually rise?accompanied by swells?and winds will also begin to strengthen. Rough weather is expected to persist around Okinawa through approximately the 29th.



Please remain alert for strong winds, high waves, and landslides associated with warning-level heavy rainfall; also, exercise great caution regarding flooding and inundation caused by rising tide levels due to storm surges.

Regarding its subsequent path, the forecast circle is large, indicating a high degree of uncertainty in the prediction. Depending on how the situation develops, the storm could approach the Kyushu or Shikoku regions and feed warm, moist air into the autumnal rain front lingering near Honshu; this could intensify the front's activity and potentially lead to heavy rainfall across Honshu.

Please pay close attention to the latest typhoon information as it becomes available.

Weather forecast for today, Saturday the 26th: A stalled autumn rain front brings steady rain across a wide area from western to eastern Japan.

2026/09/26 06:35

Today, Saturday the 26th, an autumn rain front is stalling over the main Japanese island (Honshu), stretching from western to eastern Japan. A band of rain clouds associated with this front extends from west to east, bringing rain to a wide area across these regions.



In the Kanto area, heavy rain has already been observed in some locations since the early hours of the morning; as of 6:00 AM, developed rain clouds are visible near Ibaraki and Chiba Prefectures. Rain is expected to continue, with the risk of localized heavy downpours accompanied by thunder.
Residents of Chiba Prefecture, in particular?especially in areas that previously suffered significant damage from Typhoon No. 25?should exercise extreme caution regarding the potential for new heavy rain disasters.



The band of rain clouds associated with the front is forecast to slowly move southward as the day progresses. While the rain may gradually taper off in areas facing the Sea of ??Japan, it is likely to intensify in some areas facing the Pacific Ocean. In Kyushu, heavy rain accompanied by thunder is expected in some places from midday onwards; please remain alert to changing rainfall conditions.
Even if it is not raining when you leave home, please be sure to carry an umbrella.

In Northern Japan, regions such as Hokkaido and northern Tohoku will likely see sunny skies and plenty of sunshine. However, southern Tohoku is expected to experience weather prone to rain.

Due to the rain, daytime temperatures will not rise significantly, and many areas will see a sharp drop in temperature compared to yesterday. Please not only prepare for the rain but also bring an outer layer or similar garment so you can adjust your clothing to maintain a comfortable body temperature. Meanwhile, in southern Kyushu and Okinawa, temperatures will reach 30 C or higher in many areas, making it feel hot and humid.

[Rain Warning for Rock Festival] A large-scale rock festival is taking place in Kumamoto Prefecture this weekend; be alert for localized heavy rain in the area.

2026/09/25 18:36

A rock festival hosted by a popular band is taking place in Kumamoto Prefecture this weekend. It has become a major local event, featuring a lineup of superstar artists?household names rarely seen at other rock festivals.

Here is a summary of the local weather forecast for the weekend and some tips to ensure a comfortable experience at the festival.

The weather and temperature forecast for September 26 and 27 is as follows:



Intermittent rain is forecast for both days due to an autumn rain front hovering over Kyushu, so rain gear is essential.



On September 26, the autumn rain front over Kyushu is expected to intensify, and the influx of warm, moist air from Typhoon No. 26 will likely cause the rain to become heavier.
There is a possibility of heavy downpours at the venue, so please be sure to bring rain gear such as raincoats and rain boots.



On September 27, the autumn rain front is expected to remain stationary, resulting in weather conditions similar to those of the 26th.
Rainfall is likely to intensify as the front becomes more active due to the inflow of warm, moist air from Typhoon No. 26. Just as on the 26th, please be prepared for heavy rain and remember to bring rain gear.

Regarding the festival itself, intermittent rain is expected this weekend due to an autumnal rain front.
We recommend bringing a sturdy raincoat and either rain boots or shoe covers.
It is also a good idea to bring items like Ziploc bags to protect valuables such as your wallet and smartphone. You might also want to pack spare socks.

Please keep a close eye on the latest weather updates and ensure you are in top physical condition to enjoy the best possible live music experience.

Risk of heavy rain due to successive approaching typhoons; check landslide risks on hazard maps.

2026/09/25 16:58

Typhoon No. 25, which formed in the Mariana Islands on September 16,
approached the Ogasawara Islands on the 19th,
and subsequently neared the Izu Islands and the Kanto-Koshin region on the 21st as a large, powerful storm.

The Kanto-Koshin region experienced record-breaking rainfall between the 19th and 21st, with total precipitation exceeding 800 mm in the Izu Islands, 500 mm in Shizuoka Prefecture, and 450 mm in Chiba Prefecture.

Due to this heavy rain, Level 4 landslide danger warnings were issued across 89 municipalities in seven prefectures (these warnings have since been lifted).
Over 100 landslides were reported in Chiba Prefecture, and landslides resulting in casualties occurred in Chiba, Kanagawa, and Miyazaki prefectures.

Meanwhile, Typhoon No. 26 has now formed,
and it is expected to approach the Okinawa region with strong intensity around the 27th.
Afterward, it may shift its course to the northeast and travel along the southern coast of Honshu. Depending on its path, there is a risk of heavy rain once again affecting the Honshu area.

In areas where the ground has already been loosened by previous rainfall, landslides can occur even with only a small amount of additional rain.
Please check hazard maps before heavy rain arrives to identify areas at risk.



You can search for hazard maps for your local area
using the "Wagamachi Hazard Map" (My Town Hazard Map) service.
By selecting the area you wish to check on the map,
you can view the disaster prevention page provided by the local government.

Sediment disaster hazard maps use color-coding to indicate areas requiring caution or vigilance.



Yellow: Sediment Disaster Warning Areas (areas at risk of sediment disasters)

Red: Sediment Disaster Special Warning Areas (areas where a disaster could cause building damage or pose a threat to human life)
*Note: Uninhabited mountainous areas may not be designated.



These maps also indicate evacuation shelters and assembly points, making them useful not only for understanding sediment disaster risks but also for checking evacuation routes.
Please use the hazard map as a reference to discuss disaster preparedness with your family and those close to you.



During heavy rain, please use the warnings and advisories issued by the Japan Meteorological Agency (JMA), as well as the JMA's "Kikikuru" (Landslide/Flood Risk Map) website, to help decide when to evacuate.
However, even if no official warning has been issued, it is crucial to evacuate without hesitation if you notice anything unusual about nearby cliffs or slopes.



Once a sediment-related disaster occurs, it can cause catastrophic damage to lives and property. In particular, debris flows and cliff collapses happen so rapidly that there is often not enough time to evacuate safely.

Make sure to check the risk of sediment-related disasters in your area during normal times, and commit to evacuating early when heavy rain is forecast.
We encourage you to take a look at your local hazard map.

[Kanto / Autumn Rain Front Intensifying] Rainy Weekend Ahead; Typhoon Influence Also a Concern
(Analysis by Meteorologist Atsuko Miyake)
Moist air will flow toward this front, causing it to become more active.



Here is the outlook for rain clouds later tonight.
Late tonight, rain is expected to begin in parts of the Kanto region.

After midnight and into the early morning hours on Saturday,
yellow, green, and orange shading will appear over Kanto, indicating areas where rain clouds will develop and rainfall will intensify.



Through early afternoon on Saturday, active rain clouds will continue to form, especially along the coastal areas of Chiba and Ibaraki.

From Saturday evening onward, rain clouds will gradually move away, and late at night many areas will see a temporary break in the rain.

However, on Sunday the 27th, rain clouds associated with the front will move northward again.
Kanto is expected to see widespread rain on Sunday morning.

Recently, Typhoon No. 25 brought heavy rainfall to the Kanto region, particularly in Chiba and Kanagawa, where rainfall amounts exceeded the seasonal average.



This graphic shows accumulated rainfall over the past 10 days.
Compared with the average, many areas in Kanto are shaded in dark green.
In Kanagawa and Chiba, rainfall over just the past 10 days has been five to seven times the normal amount.
The ground is already very unstable, so even light rain this weekend could trigger landslides. Please exercise caution.



Another factor requiring attention is the typhoon.
It is expected to intensify and move northward.
Around Okinawa, the typhoon will likely slow down significantly.
Although the future track remains uncertain, there is a possibility that it may affect the Kanto region in the latter half of next week.
Please continue to monitor the latest updates.



Now, let's look at the weather across the regions.
This weekend-Saturday and Sunday-many areas will experience rain.
Temperatures will also drop, and Saturday is expected to feel quite chilly.
Please take care to avoid health issues caused by sudden temperature changes.

The autumn rain front will remain stalled into next week, bringing many rainy days to the Kanto region.
In the latter half of next week, rain clouds associated with the typhoon may approach as well.
Please stay updated with the latest typhoon information.

[Front+Typhoon] Autumn Rain Front to Bring a Wet Weekend to Honshu; Okinawa and Amami Face Prolonged Severe Weather from Typhoon No. 26 (Analysis by Meteorologist Junko Miyake)

2026/09/25 14:36

This weekend, the autumn rain front is expected to become more active around Honshu.



First, here are the forecast weather charts for tonight and tomorrow night.
During the day today (Friday), Honshu will be covered by a high-pressure system from the north, bringing sunny intervals to many areas.

By tonight, a front will extend from the west, and tomorrow (Saturday) it is expected to stall from western Japan to the Pacific side of eastern Japan.

Moist air circulating along the edge of the high-pressure system, as well as warm, humid air around the typhoon, will flow toward the front. As a result, the autumn rain front will become more active, and some areas may see heavier rainfall.



Here is the rainfall forecast.
Around midnight on Saturday the 26th, rain clouds will begin to cover parts of western and eastern Japan.

In the Kanto region, rainfall may intensify from the early hours through dawn.
From morning to midday, rainfall will also strengthen in western Japan.
Kanto will continue to see areas of heavier rain, especially along the coast.



From early afternoon to evening, the rain clouds are expected to gradually move southward, and many areas will see a temporary break in the rain at night.

However, on Sunday the 27th in the morning, rain clouds associated with the front will move northward again.

During the daytime this weekend, many areas will need umbrellas.

In southern Kanto, where Typhoon No. 25 brought heavy rain recently, the ground remains very unstable. Even light rainfall could trigger landslides, so please exercise extreme caution.



Another factor requiring attention is Typhoon No. 26.

Typhoon No. 26 is currently located over the sea east of the Philippines and moving westward.
It is expected to intensify and develop a storm zone by Saturday.
After that, it may approach Okinawa and the Amami region with strong intensity.

The typhoon is currently moving at 20 km/h, but as it nears Okinawa, its speed is expected to slow to around 10 km/h and then become even slower.

This means Okinawa and the Amami region may experience a situation where the typhoon remains nearby for at least two to three days, leading to prolonged severe weather conditions.

From the 27th to the 30th in Okinawa, and from around the 28th to the 30th in the Amami region, please be alert for strong winds, high waves, and storm surges.

Depending on the typhoon's track, heavy rainfall may also become a concern in Okinawa and the Amami region.
Please continue to monitor the latest updates.



Now, here is the weather for today through the weekend.

Clouds will increase tonight, and some areas in the Kanto region may see rain.

On Saturday and Sunday, many areas from Okinawa to southern Tohoku will experience rain.
Temperatures on Saturday will be notably cool, with Osaka and Nagoya around 23C, and Tokyo and Sendai around 21C.
Be sure to prepare rain gear and bring a jacket when heading out.

Rain will continue through Sunday, and some areas will remain on the cooler side.



Here is the weekly forecast.
From Sunday the 27th through Wednesday the 30th, Typhoon No. 26 will approach Okinawa.
Please stay alert for strong winds, high waves, storm surges, and heavy rain over an extended period.

Around Honshu, the autumn rain front will remain in a stagnant pattern.
As the typhoon moves northward, the front near Honshu is also expected to become more active.
Later next week, there is a possibility that the typhoon may approach Honshu as well.
Please continue to check the latest typhoon information.

[Weekly Weather Forecast for the Kanto Region] Rain likely throughout the coming week; stay alert for Typhoon No. 26 and the autumn rain front. What precautions should be taken regarding the prolonged rainfall?

2026/09/25 14:29

The Kanto region has seen many rainy or cloudy days since the start of September, including significant heavy rainfall caused by Typhoon No. 25. Over the coming week, the region is expected to experience unsettled weather with frequent rain, driven by the autumn rain front and Typhoon No. 26.



Today, the 25th (Friday), the Kanto region is under the gentle influence of a high-pressure system, and many areas are currently seeing sunshine.
However, moist air will gradually flow in later today, leading to increasing cloud cover. Rain is expected to begin falling as the evening progresses, so those returning home late will likely need rain gear.

Tomorrow, the 26th (Saturday), a front is forecast to extend from western Japan toward the vicinity of the Izu Islands. The Kanto region is likely to experience rainy weather, so rain gear will be necessary for any outings. Please stay alert to the rainfall, as the rain may intensify locally.



Typhoons and tropical depressions are also marked as "Low" (low-pressure systems) on the map.

From the day after tomorrow, the 27th (Sunday), onwards, the autumn rain front is expected to remain stationary near the southern coast of Honshu. The Kanto region will likely see predominantly rainy or cloudy weather. Current forecasts suggest that the movement of Typhoon No. 26 will slow down near the Nansei Islands. With the autumn rain front positioned to the north of the typhoon, the warm, moist air flowing from the storm could intensify the front's activity. Localized heavy rainfall is possible around the front, so please remain cautious of the changing weather conditions. While there is still some uncertainty regarding the typhoon's path, one model (as shown in the weather map above) predicts that the typhoon will move east-northeast along the southern coast of Honshu between Friday, October 2, and Saturday, October 3. If it follows this trajectory, there is a risk of heavy rain caused by the typhoon's main rain clouds in the Kanto region.
Please check the latest weather forecasts and typhoon information, and take early precautions against heavy rain.



Regarding high temperatures, readings across the Kanto region are expected to drop significantly tomorrow, Saturday the 26th, compared to today, likely hovering just above 20C. You will need a long-sleeved outer layer.
Temperatures are expected to rise again around Tuesday the 28th, bringing back humid, sultry conditions.
Please adjust your clothing accordingly and take care to stay healthy.

# Impacts of prolonged or heavy rain and points of caution
The ground remains loose in some areas due to the heavy rain from the recent Typhoon No. 25. As rainy days are expected to continue, please avoid approaching dangerous slopes or cliffs.
Additionally, levee breaches in Chiba Prefecture have caused extensive flooding. When carrying out recovery work, please prioritize your personal safety and check the latest weather forecasts before proceeding.
# Management of fields and crops
Heavy rains?including those from the recent Typhoon No. 25?have caused damage such as field inundation and flooding of greenhouses, particularly in Chiba Prefecture.
Rainy weather is forecast to continue, and there is a risk of further heavy rain depending on frontal activity and the path of Typhoon No. 26.
It is advisable to inspect and clear drainage systems of any blockages caused by the recent heavy rains to prepare for future downpours. Prolonged rain and high humidity create conditions favorable for the spread of crop pathogens and pests, so you will likely need to take measures to address these issues.
Please also exercise great caution when entering muddy areas?whether for recovery efforts or routine farm work?or when operating agricultural machinery, as these situations can be hazardous.
When working, be sure to check the latest weather forecasts and prioritize your personal safety; also, take precautions against heatstroke by staying hydrated.

Typhoon No. 26 (Surigae): Risk of approaching Okinawa with strong intensity heading into the start of the week.

2026/09/25 06:59

As of 6:00 a.m. today, the 25th, Typhoon No. 26 is located east of the Philippines and is moving west-northwest at a speed of approximately 20 km/h.

? Typhoon No. 26: 6:00 a.m., Friday the 25th
==================
Center location: East of the Philippines
Movement: West-northwest at 20 km/h
Central pressure: 1000 hPa
Max. wind speed: 20 m/s (near center)
Max. instantaneous wind speed: 30 m/s
==================



As the typhoon moves through waters with high sea-surface temperatures, it is expected to intensify while traveling west-northwest. By Sunday the 27th, it is forecast to reach "strong" intensity and move south of Okinawa, accompanied by a zone of gale-force winds. Subsequently, it is expected to shift its course from a northerly to a more easterly direction, moving south of Japan by Tuesday the 29th.

The typhoon is expected to slow down as it approaches Okinawa, raising concerns about prolonged impacts. Effects are likely to begin around Sunday the 27th; depending on the typhoon's path and intensity, there is a risk of severe weather conditions.
Please make good use of the sunny spells expected through tomorrow and take early precautions against the typhoon in preparation for the prolonged impact.

Weather for today, Friday the 25th: Sunny and calm in Northern Japan; mostly cloudy from Eastern to Western Japan.

2026/09/25 06:30

Although a high-pressure system will cover the area around Japan today, the 25th, the influence of moist air means skies will be mostly cloudy across regions from Eastern to Western Japan.



Northern Japan will enjoy sunny and mild weather. This morning, Numakawa in Hokkaido recorded a low of -0.4C, marking the first sub-zero temperature of the season (excluding Mount Fuji). Daytime highs will reach around 20C, making for comfortable conditions, though you should be mindful of the temperature difference between morning/evening and midday.
Additionally, there is a chance of passing showers in the southern Tohoku region during the morning, so it would be wise to carry a folding umbrella when heading out.

From Eastern to Western Japan, clouds will spread, but there will also be sunny spells during the day. Daytime temperatures will be high, particularly in Western Japan, where they are expected to reach around 30C; please take precautions against heatstroke. In the Kanto region, temperatures will hover around 26C?avoiding extreme heat?but it may feel somewhat muggy. As the area of ??rainfall expands into the evening, those returning home late should carry rain gear.

Okinawa will see sunny skies in many areas. However, as passing showers may occur in the afternoon, please keep an eye on changing weather conditions.

How far will the floodwaters reach in your town? What a flood hazard map reveals.

2026/09/24 15:26

Have you ever looked at a hazard map?
These maps, created and published by local governments, show information such as local disaster risks, evacuation sites, and evacuation routes to help people prepare for natural disasters.
They provide crucial information that allows you to understand potential disaster risks in advance and take immediate, decisive action to evacuate when the need arises.

Among these, "flood hazard maps" use color-coding to indicate which areas might flood?and to what extent?in the event of heavy rain causing rivers to swell or levees to breach.
You can view them via paper maps distributed by local governments or online.
If you search for the Geospatial Information Authority of Japan's "Overlay Hazard Map" (Kasaneru Hazard Map), you can view various disaster risks layered together on a single map.





The colored areas on the map indicate zones where flooding is predicted to occur.

The phenomenon of urban areas, houses, and fields being covered by water is known as *shinsui* (inundation/flooding),
and the depth of the water (measured from the ground surface to the water level) is referred to as *shinsui-shin* (inundation depth).
These maps allow you to see at a glance how far the water might spread and how deep it could get in your area during a flood.



*Note: When roads or farmland are covered by water, the term *kansui* (surface flooding/submergence) is sometimes used.


In addition to flood hazard maps, there are also hazard maps for "internal flooding" (which occurs when rainfall exceeds the drainage capacity of the sewer system) and for sediment-related disasters (such as landslides). Depending on the region, some local governments create hazard maps covering various types of disasters?such as volcanic eruptions, tsunamis, storm surges, and irrigation pond failures?so be sure to check what is available in your area.

Hazard maps are a vital tool for disaster preparedness.



Reviewing these maps during normal times?before a disaster strikes?enables you to act without hesitation when an emergency occurs.
Use them as a starting point for discussions with your family and those close to you about important details, such as which evacuation shelter to go to and which routes to take.
