Weather for today, the 10th (Monday) Typhoon No. 13 is moving away, and Typhoon No. 15 is approaching

2026/08/10 06:30

Typhoon No. 13 is expected to head towards the continent, while Typhoon No. 15 is expected to move northward through the east of Japan and approach Honshu.



Due to the influence of the high pressure system extending from Primorye towards Sakhalin, many places on the Sea of Japan side will receive sunlight. On the other hand, on the Pacific side, there will be many hours of cloudy weather due to the influence of humid air. Winds will gradually become stronger on the Northeast Pacific side towards the end of the night. Please be careful of high waves in coastal areas. It will be safer if you prepare for a typhoon early.
There is a risk of sudden changes in the weather in eastern Japan from the afternoon. Please take a folding umbrella with you when you go out.
In eastern and western Japan, temperatures are expected to drop slightly, but it is expected to be extremely hot. Please be careful of heat stroke.
Typhoon No. 13 will move away from the mainland, but rain will remain in Okinawa. Be careful of the sideways rain. The waves will continue to be high, so please do not get close to the sea unnecessarily.

How many typhoons are approaching Japan

2026/08/09 22:34

We are currently in the middle of typhoon season! ! Three typhoons are occurring near Japan. When a typhoon makes landfall, the area is directly hit by strong winds and heavy rain, potentially causing significant damage. However, surprisingly few typhoons make landfall. First, let's talk about the typhoon's landfall.

Typhoon landfall, approach, and passage have different definitions.
"Landfall" refers to when the center (eye) of a typhoon reaches the coastline of Hokkaido, Honshu, Shikoku, and Kyushu.
"Approaching" refers to the state in which the center of the typhoon approaches within a 300 km radius of the location or area. "Approaching" is used not only when approaching mainland Japan, but also when approaching islands such as Okinawa and the Ogasawara Islands.
"Passage" is used when the center of a typhoon crosses a small island or peninsula and returns to the sea in a short period of time. For example, when passing through the main island of Okinawa, it is expressed as "passing through" rather than "landing."

Actually, 608 typhoons occurred from 2001 to 2025. On average, about 24 typhoons occur each year. Among them, 292 typhoons approached. Approximately half of the typhoons approached within a 300km radius of Japan. There were 75 typhoons that made landfall, making up only about 10% of the total.

When it comes to where typhoons land, the overwhelming majority are in Kagoshima Prefecture. Next are Kochi prefecture, Wakayama prefecture, Shizuoka prefecture, and Nagasaki prefecture. The only typhoon that made landfall in 2026 was Typhoon No. 6, which made landfall in Wakayama Prefecture.

As of 2026, 16 typhoons have occurred. This year, the El Nino phenomenon is expected to occur and there will be more typhoons. As the number of typhoons increases, the number of typhoons that make landfall will also increase. Let's take proper measures and prepare for the coming typhoon.

[Triple typhoon] Affects the weather during the Obon period - Typhoons No. 13, No. 15, Tropical cyclone

2026/08/09 13:19

Typhoon No. 13, which is large and extremely strong, is expected to maintain its strong strength on the 9th and move slowly westward through the East China Sea.



Extremely strong winds will continue in the Okinawa region into the 10th, and the sea will be flooded with heavy rain. Heavy storms are expected in the Amami region on the 9th. Additionally, on the 9th, atmospheric conditions in the Okinawa region will become extremely unstable due to the influence of rain clouds that have developed around the typhoon, and there is a risk of intermittent heavy rain.

The typhoon is expected to gradually move away from the Okinawa and Amami regions, but we still need to be on guard against disasters caused by heavy rain, strong winds, and high waves.

Meanwhile, Typhoon No. 15 is moving westward over the eastern seaboard of Japan, and is expected to change its course to the north-northwest on the 10th, approaching the coast of Sanriku, and heading northwest off the coast of Sanriku on the 11th. The weather during the Obon holiday may be affected, so if you are planning leisure activities in the mountains, rivers, or the sea, please consider reconsidering your plans based on the latest forecast.



Furthermore, a new tropical cyclone that is expected to develop into a typhoon is moving eastward near Ogasawara.



Depending on its path, Japan may be affected, so pay attention to the latest typhoon information.

The heat around Honshu is severe from Tohoku to Kyushu, and there are likely to be places with extremely hot days of over 35c. Be careful not to get heat stroke, drink plenty of water and take adequate breaks.



In the afternoon, atmospheric conditions will be unstable due to cold air in the upper atmosphere, rising temperatures during the day, and moist air. The probability of lightning strikes is high across a wide area from northern to eastern Japan, with the probability of lightning occurring in some places exceeding 90%, especially in the southern Tohoku, northern Kanto, and Koshin regions. In the afternoon, rain clouds and thunderclouds are likely to develop mainly inland and along mountains, and there are likely to be some places where there will be very heavy rain accompanied by thunder. Be careful of sudden changes in the weather in the afternoon, and be careful of sudden rain and thunderstorms even in the plains.
Lightning, tornadoes, and other violent gusts may occur, so if you see signs of a sudden change in weather, such as approaching black clouds or hearing thunder, please take precautions to ensure your safety by evacuating to a sturdy building.

There is a risk of a linear rain belt forming in Niigata Prefecture. Be careful of flooding in low-lying areas and rising water levels in rivers.

2026/08/08 15:54

At 3:08 p.m., the Japan Meteorological Agency announced the immediate forecast for a linear precipitation zone, saying, ``In Chuetsu, Niigata Prefecture, there is an increasing possibility that a linear precipitation zone will occur within the next three hours, and extremely heavy rain will continue to fall in the same place.There is a risk that the risk of life-threatening disasters will rapidly increase.''
At 3:20 p.m., it was announced that ``heavy rain is falling in the vicinity of Nagaoka City, Niigata Prefecture, at a rate of about 100 mm per hour, and the risk of disaster is rapidly increasing'', announcing a record-breaking heavy rain event in a short period of time.

The atmospheric conditions in Niigata Prefecture are extremely unstable, and thunderclouds are developing near Chuetsu.
AMeDAS observed a torrential rain of 89.0 mm at Sumon in Uonuma City, Niigata Prefecture in the hour ending at 3:20 p.m., making it the heaviest rainfall ever observed at this location.

In Kaetsu, Chuetsu, and Joetsu, please be careful of flooding of low-lying land and rising water in rivers until late at night on the 8th today, and in Chuetsu, be careful and be on guard against landslides until late at night on the 8th today.
Also, in Niigata Prefecture, there is a risk of lightning, tornadoes, severe gusts of wind, and hail late into the evening of today, the 8th, so please be careful.

#What is record-breaking heavy rain information

It is announced by the Japan Meteorological Agency when short-term heavy rain that only occurs once every few years is observed and analyzed.

If the rainfall standards are met and the "danger" (purple) status of
Kikikuru (danger distribution) appears during the heavy rain warning announcement, the name of the observation point, city, town, etc. where the
heavy rain was observed will be clearly stated.

Rainfall standards are determined for each prefecture/prefecture forecast area, based on the historical record of first or second place in hourly rainfall.

#Record heavy rain information has been announced for areas where...

It means that heavy rain is falling that can lead to landslides, inundation of low-lying land, and flooding.

Let's check where the risk of disaster is actually increasing
Kikikuru (risk distribution).
