Northern Japan is as cheerful as May, with temperatures expected to be similar to late June in Tokyo over the weekend.

2026/04/09 07:06

Today, the 9th (Thursday), a high pressure system will cover northern Japan and the Kanto region, and sunshine is expected to reach the area during the day. As warm air flows in from the south, temperatures are expected to rise, with many places in northern Japan reaching a maximum of over 15 degrees Celsius, and many places expected to experience temperatures similar to early to mid-May. The temperature difference between morning and evening and during the day will be large, so please be careful of the temperature difference.
The Kanto region also has many sunny spells during the day, and it will be warm, typical of this time of year.
Western Japan will have a cloud-dominated sky, but the temperature will be around 20c in many places, and it is likely to be as warm as normal in many places.

The predicted maximum temperature is Sapporo 17c, Sendai 19c, Tokyo 20c, Nagoya 21c, Kanazawa 22c, Osaka 21c, Kochi 20c, Fukuoka 20c.



This weekend, from the 11th (Saturday) to the 12th (Sunday), the temperature is expected to reach +12c at an altitude of around 1500m, which is warm for this time of year and is expected to flow into the vicinity of Japan. As the area around Japan is covered by high pressure, the weather will improve in many places, and it is likely to be unseasonably hot in many places this weekend.

On Saturday the 11th, temperatures are expected to exceed 20c from western Japan to eastern Japan and the southern part of Tohoku. In central Tokyo, the expected maximum temperature is 27c, which is similar to late June. This is the time when people are not used to the heat yet, so those who exercise should be careful to avoid heat stroke by drinking plenty of water.
The warm weather will remain on the 12th (Sunday), with temperatures expected to be similar to those from May to early June, mainly in northern and eastern Japan. It is expected that it will be summer in Nagoya and Osaka as well.
Then, from around the 13th (Monday), a low pressure system will approach from the west, resulting in cloudy and rainy weather, and temperatures are expected to settle down to normal levels.

Today's 9th (Thursday) weather The weather is going downhill from the west, sunny in northern Japan

2026/04/09 06:30

Today, the 9th (Thursday), the high pressure system that brought sunny skies yesterday (8th) will move away to the east of Japan, and low pressure systems and fronts will move eastward from the west. In northern Japan, which is covered by high pressure, many places will be sunny, but in western and eastern Japan, the weather will go downhill.



Northern Japan will be covered in high pressure and will have sunny skies in many places. Although there will be times when clouds will spread out, the weather does not seem to deteriorate. However, please be careful of strong winds in Hokkaido, as the winds are stronger mainly in the coastal areas.

On the other hand, the weather in western and eastern Japan is gradually going downhill.
In Kyushu, it is expected to start raining around noon, with heavy rain expected at night. Be careful of lightning strikes, gusts of wind, and sudden heavy rain.
The rain is expected to spread over Chugoku and Shikoku in the evening, and from the Kinki region to the Tokai region and Hokuriku region by late evening. It looks like there will be places in the Kanto region where it will start to rain late at night. It is expected that it will be sunny in many places, especially in eastern Japan, during the day, but please prepare rain gear for the time you return.

Okinawa will be sunny and the sun will shine.

Weekly weather Low pressure and fronts pass periodically; weather will deteriorate over a wide area on the 10th (Friday)

2026/04/07 19:42

Today, the 7th (Tuesday), low pressure systems moved east-northeast around Hokkaido and the southern coast of Honshu, bringing rain to many places across the country. In northern Japan and the Hokuriku region, there are places where snow is falling, mainly along the mountains, due to the influence of cold air in the sky.

After this, a high pressure system will emerge from the west and is expected to cover the Honshu region by tomorrow, the 8th (Wednesday). The weather will improve in many places, and it will be sunny in many places. However, please be aware that near northern Japan, there is a large gradient in atmospheric pressure between the high pressure overhanging from Honshu and the low pressure near the Sea of Okhotsk, and winds are expected to increase.



Over the next week, low pressure systems and fronts will periodically pass near Japan, and there will be days when the weather will deteriorate.

On the 9th (Thursday), a low pressure system with a front will move eastward from near the Yellow Sea. It will start raining in the afternoon in western Japan.

On the 10th (Friday), a low pressure system will move toward the Sea of Japan and continue to develop as it moves northeast. Rain will fall over a wide area near Japan as the front passes. Please be careful as the rain may become heavier temporarily. It is also possible that low pressure and winds blowing toward the front will cause torrential rain. Please check the latest information and be careful when going out.

On Saturday the 11th, the weather will improve in western and eastern Japan, but there will still be some rain in northern Japan and the Hokuriku region. In addition, strong winds will continue in the Hokkaido region, which is close to a low pressure system.

12th (Sunday) The area around Honshu will be covered in high pressure and it will be sunny in many places, but a front is expected to extend from the continent to the south of Kyushu. There will be some places in the Kyushu region where it will rain.

From Monday 13th to Tuesday 14th, a front will extend from the continent to the southern coast of Honshu, and a low pressure system will form above the front, which is expected to move eastward. Rain is expected to gradually spread from western Japan to northern Japan.




Temperatures are expected to be around average or high in many places throughout the period.
In particular, on the 9th (Thursday), the temperature will be 21c in Sendai, the same as late May, 18c in Sapporo, 22c in Kanazawa, and 27c in Naha, the same as mid-May.
On the 11th (Saturday), the temperature in Tokyo will be 26c, which is similar to mid-June, and it will be a cheerful weather ahead of the season.
This is the time when you are not used to the heat yet, so please take precautions against heatstroke by taking frequent breaks and hydrating.

Weather for today, the 7th (Tuesday): Widespread rain, but the weather is improving from the west; the night is getting colder and stronger.

2026/04/07 06:26

Today, the 7th (Tuesday), a front and low pressure system are expected to move south of Honshu. In addition, another low pressure system will move over the northern Sea of Japan and near Sakhalin, respectively. As a result, rain is expected to fall over a wide area from western to northern Japan. However, it looks like the weather will start to improve from the west in the afternoon.



It's a rainy day in northern Japan due to the influence of the low pressure system and shear line moving through the Sea of Japan. Winds are strong in coastal areas, and on the Pacific side of Tohoku, please be careful of traffic disruptions and damage to buildings caused by strong winds from the west.
As cold air flows in at night, there will be places where it snows along the mountains. Please be aware of changes in the weather.

In the Kanto region, clouds tend to spread throughout the day, and the sky is likely to rain towards the evening. Please bring rain gear when going out.

West of the Tokai region, the weather is improving from the west. There will be some rain in the Tokai and Hokuriku regions in the afternoon and in western Japan until around noon, but the sun will gradually return. Please be careful not to leave your rain gear behind when returning home.

The temperature will be lower than the previous day in various places, and many places will have temperatures typical of this time of year during the day. It is expected to be even colder in the morning as cold air moves in at night. Please be careful when choosing your clothes.

The front is moving south across the East China Sea, and there is a risk of warning-level heavy rain in southern Kyushu and the Nansei Islands from now until the 7th.

2026/04/06 21:28

A low-pressure system accompanied by a front is located in the East China Sea and is moving eastward, and is expected to move southward in the East China Sea and pass near the Nansei Islands by early morning on the 7th.
As warm, humid air flows toward this low pressure system and front, atmospheric conditions will become extremely unstable in southern Kyushu and the Nansei Islands.
As a result, cumulonimbus clouds will develop locally in Kagoshima Prefecture through the evening of tomorrow 7th and in Okinawa Prefecture through tomorrow 7th, and there is a risk of thunderstorms, tornadoes, and other violent gusts.



[Rain Forecast]
In Kagoshima Prefecture, from the early evening of the 6th today to the early afternoon of the 7th tomorrow, and in the main island of Okinawa and the Sakishima Islands until the 7th tomorrow, very heavy rain or torrential rain accompanied by localized thunderstorms is expected to occur, with the risk of warning-level heavy rain. If rain clouds develop more than expected or if heavy rain continues to fall in the same area, a heavy rain warning may be issued.

A day full of spring sunshine, sweaty and cheerful during the day

2026/04/06 12:06

Today will be covered in high pressure and the weather will be calm and sunny across the country.



It is expected to rain in Kyushu from late at night.
If you will be returning home late, it is a good idea to have a folding umbrella.



In addition to the warm air flowing in from the south, the weather will be sunny and the sunlight will be strong. As a result, temperatures will continue to be warmer than normal in many places as they were yesterday, and temperatures are expected to be similar to late April to mid-May.
In Nagoya, the forecast is for a summer day of 25c, and it looks like the temperature will be similar to mid-May.

There is a possibility that yellow dust from the continent will fly in, mainly in western Japan.
Please be careful of dirt on futons, laundry, cars, etc., worsening of visibility,
If you have a respiratory disease, please be careful of worsening symptoms.
As the temperature rises, more pollen is expected to be scattered, so if you are sensitive, please take appropriate precautions when going out.

Weekly weather The weather changes frequently in short cycles. Be careful of stormy weather on the 9th and 10th.

2026/04/06 07:29

From now on, the weather will change in short cycles, and when a low pressure system passes near Honshu on the 9th to 10th, there is a possibility of rough weather.



Today, the 6th (Monday), it will rain from evening to night in the Nansei Islands, Kyushu, and Hokkaido. In the early hours of tomorrow, the 7th (Tuesday), there is a risk that extremely heavy rain of over 50mm per hour will fall in southern Kyushu, so caution is advised. On the 7th, the rain will spread further, with some places experiencing rain and thunderstorms in eastern and northern Japan. In Hokkaido, due to the influence of cold air in the upper atmosphere, it is likely that there will be snow in some places, mainly in northern Hokkaido, into the 8th (Wednesday).

The next day, the 8th (Wednesday), will be covered by high pressure, and the weather is likely to improve in many areas. However, the next day, the 9th (Thursday), the next low pressure system will approach from the west, so it would be a good idea to take advantage of the sunshine by drying your laundry outside.

On the 9th (Thursday), the weather will be downhill in western Japan due to the effects of low pressure and fronts. The low pressure system is expected to develop as it passes through the Sea of Japan, and there is a possibility of rough weather on the 10th (Friday), mainly on the Sea of Japan side. Please pay close attention to future weather information as the rain and wind may become stronger and waves may become higher at sea.

From now on, the temperature will be higher than normal, and there will be many summer days with temperatures above 25c. However, on the 7th (Tuesday), a strong cold air will temporarily flow in, and there are likely to be places where the temperature will drop significantly compared to the previous day, the 6th, especially in areas along the Sea of Japan such as northern Japan and Hokuriku. Please choose your clothing carefully.

Tomorrow, the 6th (Monday), the weather from western to eastern Japan approaches a summer day with temperatures of over 25 degrees Celsius, and the weather in Hokkaido and western Japan is on a downward slope.

2026/04/05 21:02

Tomorrow, the 6th (Monday), which marks the end of the week, warm air from the south will easily enter the Honshu area, and in many places in western Japan and the Pacific side of eastern Japan, temperatures will be higher than on the 5th (Sunday). Temperatures in many areas will be similar to those in May, and there are likely to be some summer days with temperatures above 25c. You may be able to go without a jacket during the day, but be sure to stay hydrated.



It is expected to be sunny in many places in the morning, but there is a possibility that yellow dust from the continent will fly in, mainly in western Japan. Please be careful of dirt adhering to laundry or cars, worsening of visibility, and worsening of symptoms if you have a respiratory disease. Cedar pollen and cypress pollen continue to scatter, so if you are sensitive, please take sufficient precautions when going out.



In western Japan, rain clouds associated with low pressure and fronts will gradually approach from the afternoon. In the Nansei Islands and Kyushu, it will start to rain from evening to night, and there will be some places with thunder. In southern Kyushu, there is a possibility of extremely heavy rain of over 50 mm per hour late at night, so please be careful about how the rain falls. It seems that there will be places in the Chugoku and Shikoku regions where it will start raining late at night.
In Hokkaido, a low pressure system moving across the continent and a trough of pressure associated with the low pressure system are approaching. There will be places on the Sea of Japan side where it will start to rain late at night. If you're going to be returning home late, it might be a good idea to bring an umbrella with you.

Today, the 5th (Sunday), the weather will improve in the Kanto region, but be careful of sudden rain.

2026/04/05 11:57

Yesterday, the 4th (Saturday), the passage of a low pressure system and front caused widespread rain across the country. In the Kanto region, the rain stopped on the morning of today, the 5th (Sunday), and the weather started to improve. After this, the sunshine is expected to return, and temperatures are expected to rise, especially in inland areas, leading to summer days in some places. However, there are likely to be some areas where it will rain from the evening onwards, so please be careful of sudden rain or lightning.





This is the weather, maximum temperature, and precipitation probability in the Kanto region today, the 5th (Sunday). Temperatures in inland areas are expected to rise by 10 degrees Celsius compared to yesterday, resulting in summer days of 25 degrees Celsius in some places. I think many people go out to see the cherry blossoms on Sunday, but this is the time when people are not used to the heat yet, so be sure to take frequent breaks and stay hydrated.



Today, the 5th (Sunday), the weather is expected to improve and it will be a good day to go out, but in the Kanto region, especially inland areas, you should be careful of sudden rain from the afternoon onwards. In the Kanto region, atmospheric conditions will become unstable due to the effects of rising temperatures on the ground, moist air, and cold air above, making it easier for rain clouds to develop.
It is expected to rain in some places in the northern Kanto region from the afternoon, and in the southern part of the country after the evening, accompanied by localized thunderstorms.
Rainy conditions are likely to continue until dawn tomorrow, the 6th (Monday).
If you are planning to go out, please prepare a folding umbrella and pay attention to changes in the sky.

Temperatures will rise today on the 5th (Sunday) and tomorrow on the 6th (Monday), with some summer days in western and eastern Japan having maximum temperatures of over 25c.

2026/04/05 10:29

There is a low pressure system near Sakhalin and off the coast of Akita that is moving northeast.
Also, a front is passing through the Kanto region and extending into the Okinawa region.
Meanwhile, there is an anticyclone in the East China Sea that is moving eastward.
Currently, it is raining on the Sea of Japan side of northern Japan and the Okinawa region.



Today, the low pressure system and front will gradually move away.



There will be rain in some places on the Sea of Japan side of northern Japan, parts of western and eastern Japan, and Okinawa, but there will be many places where sunlight will reach during the day.
However, the atmospheric conditions in Okinawa are unstable and there is a risk of heavy rain accompanied by thunder, so please be careful.
The maximum daytime temperature is higher than normal nationwide, and inland areas of the Kanto region are likely to experience summer days of 25 degrees or higher





Tomorrow, the 6th (Monday), a low pressure system and front will slowly approach from the west.
As a result, it is expected to start raining in the Okinawa region in the afternoon and in the evening in Kyushu, Shikoku, Hokkaido, and Tohoku.
However, many places will be sunny during the day, and the number of summer days with maximum daytime temperatures of 25 degrees or higher in western and eastern Japan is likely to increase.
