The front is extending from central China, through Kyushu and southern Japan, and into the waters near Ogasawara. Additionally, there is a low pressure system in the East China Sea above the front, which is slowly moving eastward.
Today, the 24th (Wednesday), the rainy season front will become active and it will rain widely across western Japan. There is a risk of heavy rain in Kyushu and Shikoku, so vigilance is required.



Warm, humid air is flowing in from the south towards the rainy season front, and rain clouds have developed over Kyushu since the morning. In northern Kyushu, active rain clouds are likely to pass through the afternoon, forming linear precipitation bands, and the risk of heavy rain disasters may increase rapidly. Please try to evacuate early.
The rain is expected to spread to Shikoku and China, and even in Shikoku there is a risk of extremely heavy rain, so caution is required.

It will start raining in the Kinki region from around noon and in the Tokai region from night, and the rain will be heavier mainly on the Pacific side. Please bring rain gear when going out.

The sky in the Kanto region is dominated by clouds. During the day, the temperature will exceed 25c, making it feel a bit hot and humid.

Northern Japan and Hokuriku will be covered in high pressure and will have sunny skies in many places. It looks like it will be a comfortable experience during the day, but please be careful when choosing what to wear as the temperature difference between morning and evening is large.

It looks like Okinawa will be sunny and the blue sky will spread out. Please be careful of heat stroke.

There is a risk of a linear rain band forming in northern Kyushu. Strict vigilance against landslides will be in place until the 24th tomorrow. Also in western Japan, watch out for heavy rain disasters through the 25th.

2026/06/23 18:27

The rainy season front is expected to move north. Typhoon No. 7 is also expected to change its course to the east and head north.



Due to the influence of the seasonal rain front, western Japan will experience widespread rain. There is a risk of extremely heavy rain, especially in Kyushu and Shikoku. It is necessary to be on guard against landslides, flooding of low-lying areas, and rising and flooding of rivers. It starts raining in the Tokai region from night onwards, so if you're going to get home late, it's a good idea to bring an umbrella with you. The Kanto region will be covered in clouds and the weather will be uncomfortable. The temperature and humidity are both high, making it feel hot and humid. Hokuriku and northern Japan are covered in high pressure and the weather is heading towards recovery. The sun will shine in many places, and temperatures will rise significantly compared to today. The temperature can vary greatly throughout the day, so please dress accordingly.

[Typhoon information] New typhoon No. 8 has occurred. Be wary of double typhoon trends.

2026/06/23 13:33

As of noon today, Tuesday, the 23rd, extremely powerful Typhoon No. 7 is moving at a slow speed northwestward over the sea east of the Philippines. It is expected to continue to grow and move northward, gradually approaching Okinawa.

In addition, another typhoon No. 8 occurred in the Mariana Islands at around 9:00 a.m. today, Tuesday the 23rd. It is currently moving towards the west.

#Typhoon No.7 23rd (Tue) Noon
==================
Strength Very strong
Center location East of the Philippines
Traveling speed Northwest 10km/h

Movement speed West 15km/h
Central pressure 1004 hPa
Maximum wind speed 18 m/s (near the center)
Maximum instantaneous wind speed 25 m/s
=================



Looking at the predicted course of each typhoon, Typhoon No. 7 is expected to approach the Sakishima Islands area around the 25th (Thursday) with strong winds and strong winds. Waves are gradually increasing around the Sakishima Islands and the main island of Okinawa, and around the 25th (Thursday) there is a risk that the waves will be over 7 meters high in the vicinity of the Sakishima Islands. Strict vigilance is required against heavy rain, strong winds, and high waves. There is also a possibility that Typhoon No. 7 will approach Honshu with strong winds.
Meanwhile, Typhoon No. 8 will continue to move northwest, but is expected to change its course to the northeast around the 26th (Friday). The current forecast is that it will pass through the waters between the Izu Islands and the Ogasawara Islands, and caution and vigilance are required in the Izu Islands and the Ogasawara Islands due to heavy rain, strong winds, and high waves accompanied by swells.
The interaction between Typhoon No. 7 and Typhoon No. 8 may complicate the movement of each typhoon near Honshu. At this point, there is still a wide range of predictions about the path of the typhoon, but please be careful when predicting the path of the typhoon.

Also, as warm, humid air from the typhoon flows toward the seasonal rain front, heavy rain may occur even in areas far away from the typhoon. Please be sure to prepare for heavy rain disasters.

Weather for today, the 23rd (Tuesday): Rain in northern Japan, Shikoku, and Kyushu. Be careful of lightning and gusts of wind.

2026/06/23 08:03

Today, the 23rd (Tuesday), it will be rainy in northern Japan, Shikoku, and Kyushu. Other areas are expected to see periods of sunshine, but there will also be some rain in the Kanto-Koshin and Tokai regions.



The rainy season front extends from the continent to the south of Japan, passing through the East China Sea and south of Kyushu. There is a low pressure system in the East China Sea above the front, and it is slowly moving eastward. On the other hand, there is an anticyclone near Sakhalin that is moving south, and another anticyclone in the Sea of Japan that is slowly moving east.

Currently, it is raining in central Hokkaido, Tohoku, Hokuriku, Kinki and Kyushu.



Today, the 23rd (Tuesday), there will be a pressure trough between high pressure and high pressure from Hokkaido to the Tohoku region, and clouds will likely spread. Rain is expected to fall over a wide area. Furthermore, cold air is expected to flow into the skies over northern Japan, making the atmospheric conditions unstable, and there may be some places where it will rain and be accompanied by thunder. It is expected to rain in some places in Niigata Prefecture in Hokuriku, but the weather is expected to improve in the afternoon.

Shikoku and Kyushu are expected to experience rain as the front moves northward and a low pressure system above the front approaches from the west. There will be heavy rain in some places, accompanied by thunder. Be careful of lightning, tornadoes, strong wind gusts, and sudden heavy rain.

Other regions will experience sunny spells, but in Kanto-Koshin and Tokai areas, it will rain in places. It's safe to have a folding umbrella when you go out.

The predicted maximum temperature will be higher than normal in some parts of Kanto-Koshin and Okinawa, and will be around normal or lower than normal in other areas. From now on, it is likely that temperatures will change significantly in northern and eastern Japan due to weather changes. Please dress appropriately and be careful not to get sick due to changes in temperature.

New typhoons are expected to occur; areas near Japan should be careful of the next two typhoons

2026/06/23 05:03

The Japan Meteorological Agency has announced information on a tropical cyclone that is expected to develop into a typhoon, in addition to Typhoon No. 7, which is currently moving east of the Philippines.
Currently, the tropical cyclone is moving northwest near the Mariana Islands at a speed of 15 km/h. This tropical cyclone is expected to develop into a typhoon, with maximum wind speed near the center reaching 18 m/s at 03:00 on the 24th (Wednesday). It is then expected to move west-northwest, change its course to the north-northeast around the 26th (Friday), and head toward the waters near the Izu Islands around the 27th (Saturday).



#Tropical cyclone (as of 03:00 on June 23)
Center location: Mariana Islands
Central pressure: 1008hPa
Travel direction/speed: Northwest 15km/h
Maximum wind speed: 15m/s
Maximum instantaneous wind speed: 23m/s

The path of the typhoon is still uncertain, but there is a possibility that it will affect the Ogasawara Islands and Izu Islands.
In conjunction with Typhoon No. 7, there is a risk that it will affect areas near Japan, so please pay attention to future information.

Weather for tomorrow 23rd (Tuesday): Be careful of heavy rain in Kyushu and Shikoku

2026/06/22 18:19

The rainy season front is moving northward. Rain is expected to fall in Kyushu and Shikoku, which are close to the front, and may become heavier. Northern Japan is now in a high-pressure area, and the rain in Tohoku is likely to ease.




Okinawa/Amami receives plenty of sunlight and gets hot, so please drink plenty of water and take breaks.
In Kyushu and Shikoku, it rains intermittently, making it difficult for temperatures to rise, with many places not reaching 25c during the day. However, due to the high humidity, it is likely to be uncomfortably hot.
Western and eastern Japan will be covered in clouds, but there will be some places where the sun will reach in the afternoon, and the maximum temperature will likely exceed 25c in many places. There is a possibility of showers in the Kanto region from the afternoon. It's safe to have a folding umbrella.
The rain in Tohoku has finally subsided, and the weather will start to improve in the afternoon. There are places in Hokkaido where it rains due to the trough in the atmospheric pressure, so don't forget your umbrella.

[Typhoon No. 7] Develops into extremely strong force; fear of approaching western Japan on 27th

2026/06/22 18:00

Typhoon No. 7 is extremely strong with strong winds and is moving west-northwest in the east of the Philippines.
The central pressure is 935 hectopascals, the maximum wind speed near the center is 50 m, and the maximum instantaneous wind speed is 70 m.




There is a risk that it will approach western Japan from the 26th to the 27th.

Even if the typhoon itself is far away, the rain can suddenly intensify due to the influence of humid air, and the outside situation can change dramatically in a short period of time.
Check disaster prevention information and warnings from the Japan Meteorological Agency and local governments frequently and be prepared for changes in the situation.

Rainy season front stalls in Honshu; risk of heavy rain increases mainly in western Japan from 24th to 26th

2026/06/22 17:40

The front is stationary near Honshu, and rain and cloudy weather are expected to continue this week.

There is a risk of warning-level heavy rain in western Japan, especially from the 24th to the 26th.



Warm and humid air flows in from the southern ocean, increasing the activity of the stationary front, making it easier for rain clouds to form.
Be careful of landslides, flooding of low-lying areas, and rising river waters.



Over the coming week, there will be many cloudy and rainy days from northern Japan to western Japan, but on the 29th it is expected to be sunny mainly on the Sea of Japan side.
Other areas are likely to be cloudy, but there is a chance of sunshine.
This may be a valuable time to hang your laundry outside to dry.

Okinawa and Amami will continue to have many cloudy and rainy days.

Typhoon No. 7 (Maker Color) is heading north with strong winds, and is likely to approach Okinawa in the second half of the week

2026/06/22 07:05

As of 6 a.m. today, the 22nd, Typhoon No. 7 is located in the east of the Philippines and is moving westward at a speed of approximately 30 kilometers per hour, accompanied by strong winds.

#Typhoon No. 7 22nd (Monday) 6:00
===================/br Center position East of the Philippines
Strength Strong
Movement West 30km/h
Central pressure 955 hPa
Maximum wind speed 40 m/s (near the center)
Maximum instantaneous wind speed 60 m/s
==================



The typhoon is expected to continue to intensify and move westward until around the 23rd (Tuesday). It is then expected to change course northward around the 24th (Wednesday) and head south of Okinawa later in the week around the 26th (Friday).

Currently, there are large fluctuations in the forecast regarding the course and development of the typhoon, but there is a risk that it will approach Okinawa with strong force and bring stormy winds later this week.
There is a risk of strong rain and winds leading to rough weather, so it is a good idea to pay close attention to future typhoon information and prepare for typhoons early.
