2026/02/27 12:14

[Weather points for the next week]
+March starts with clear skies and calm weather
+3rd (Tuesday) Hinamatsuri is a cold rain
+Total lunar eclipse will be visible in some places on the night of Hinamatsuri



Today, February 27th (Friday), a low pressure system west of Kyushu will move eastward, and a front will approach the Nansei Islands.

For this reason, it will rain in western Japan and the Nansei Islands,
There will be heavy rain accompanied by thunder in some places in Kyushu and Okinawa.

Please be careful of sudden intensifying rain, lightning, gusts of wind, and hail.

Tomorrow, the 28th (Saturday), the atmospheric pressure will be weak, high in the west and low in the east,
on the Sea of Japan side, rain and snow will likely fall.



At the start of March, on the 1st (Sunday), the area around Japan will be covered by high pressure, and
it is expected that sunlight will reach many areas during the day.

However, the weather changes quickly in spring, and from the 2nd (Monday), a low pressure system accompanied by a
front will approach from the East China Sea, so the weather is likely to deteriorate from the
west in many places.

In Kyushu, it will start raining as early as around noon on the 2nd (Monday), and it is expected to rain over a wide area from the 3rd (Tuesday) to the 4th (Wednesday).
There will be heavy rain, especially in western and eastern Japan, and
the rain is likely to become stronger in many places.

In addition, the rain from the 3rd (Tuesday) to the 4th (Wednesday) will be cold as cold air will be drawn towards the low pressure system.
You also need to be careful about changes in temperature.

On the 5th (Thursday), the atmospheric pressure will once again be weak, with high pressure in the west and low pressure in the east, and
rain and snow are expected on the Sea of Japan side.

The weather will change periodically over the next week.



Now, on the night of March 3rd (Tuesday), a total lunar eclipse will occur across Japan.

If you miss this lunar eclipse, the next total lunar eclipse will be on January 1, 2029, and you won't be able to see it for a while.

Currently, there are many places nationwide where it will rain on the 3rd (Tuesday), so there will be few places where you can see a total lunar eclipse.

However, the low pressure system is moving a little faster than expected yesterday, so
the possibility of seeing it on the Pacific side of western Japan and the Nansei Islands has increased.

Also, Hokkaido is less likely to have rain clouds, so there will likely be time to see a total lunar eclipse through the gaps in the clouds.

Please note that forecasts may still change in the future, so please check the latest forecast.




On March 3, 2026, around 7:00 pm, the moon will begin to appear eclipsed, and after 8:00 pm, there will be a total eclipse in which the entire moon will be in the shadow of the Earth, turning it a coppery red.

The total eclipse ends after 9pm, but you can enjoy the changing appearance of the moon until after 10pm, when the moon returns to its original full moon state.

This is a lunar eclipse that can be seen all over Japan and is easy to observe depending on the time of day.
I hope that future rain forecasts will change and more places will be able to see a total lunar eclipse.

While the weather is warming up ahead of spring, there continues to be a noticeable lack of rainfall on the Pacific side (weather summary from February 15, 2026 to February 21, 2026)

2026/02/27 07:32

#Summary of the weather for this period (February 15th to February 21st)
The average temperature tended to be above normal in many places, as low pressure and high pressure systems alternately passed near Honshu, making it easier for warm air to enter from the south. In Hokkaido in particular, there was a marked trend in high temperatures, nearly 3 to 4 degrees Celsius above normal.

Precipitation tended to be noticeably low from western Japan to the Pacific side of eastern Japan and the Pacific side of Northeastern Japan, where it was less affected by low pressure and fronts, and there were many locations where the total precipitation for the period was 0 mm. In the Sea of Japan region from Hokkaido to the San'in area, the winter-like atmospheric pressure pattern did not last long and the influence of cold air was weak, so there were many places with below-average precipitation.

Sunshine hours tended to exceed normal years because there were many days covered by high pressure mainly from western to eastern Japan, and the sunshine hours were significantly above normal mainly on the Sea of Japan side from the San'in area to Hokuriku. On the other hand, the Sea of Japan side of Hokkaido was susceptible to the effects of low pressure, so temperatures tended to be slightly below normal.



[About the weather during this period]
#Characteristics of pressure distribution
On the 15th, a low pressure system accompanied by a front moved eastward from the west of Hokkaido through the Sea of Okhotsk while developing. Another low pressure system is heading east to the south of Japan. On the 16th, the low pressure system moving through the Sea of Okhotsk further developed, forming a temporary winter-like pressure pattern near Honshu. On the 17th, high pressure gradually became dominant around Honshu, and the winter-like pressure pattern loosened. A low-pressure system formed near northeastern China in the early afternoon, and a front became apparent by late evening, and by the 18th it had strengthened as it moved through the Sea of Japan. A low pressure system also formed over the southeast coast of Kanto and on the front south of Honshu and moved eastward, forming a temporary winter-like pressure pattern near Honshu on the 19th. Western and eastern Japan were gradually covered by high pressure, but the winter-like pressure pattern centered on northern Japan continued. On the 20th, the area around Honshu was widely covered by high pressure, and the winter-like pressure pattern centered on northern Japan was gradually dissolving. In the south of Kanto, a low pressure system accompanied by a local front developed and moved east-northeast to the east of Kanto. On the 21st, the area around Honshu was widely covered by high pressure.

#Precipitation
On the 15th, it rained in the Nansei Islands due to the influence of a low pressure system, and heavy rain was observed in places such as Kaminaka, Minamitane-cho, Kagoshima Prefecture. In Hokkaido, it started raining in the afternoon, and at night the rain turned to snow. On the 16th, due to a temporary winter-like atmospheric pressure pattern, snow became heavier on the Sea of Japan side of northern Japan, mainly in the morning. After the evening, localized rain and snow fell in the southern Kanto region due to the shear line. On the 17th, snow fell from the Sea of Japan side of northern Japan to Hokuriku, and the rain and snow in the southern Kanto region had mostly subsided around noon, but in the southern Kanto region, it started raining again at night due to the influence of a coastal front. On the 18th, a front extending from a low pressure system moving through the Sea of Japan caused snow and rain mainly on the Sea of Japan side from Hokkaido to the San'in area. On the 19th, with a winter-like atmospheric pressure pattern centered in northern Japan, winds became stronger in Hokkaido, resulting in rough weather, and a temporary heavy snow warning was issued in parts of the Sea of Japan. On the 20th, there was localized rain along the Kanto coast and thunderstorms over the Izu Islands. It rained in some parts of Okinawa due to the damp air. On the 21st, the area around Honshu was covered with high pressure, and there was almost no precipitation over a wide area.

#Temperature
On the 15th, with warm air coming in from the south, it became as warm as late March to April in a wide area. In central Tokyo, the temperature was 18.4c, which is as warm as early April. On the 16th, due to the influence of cold air moving south, temperatures dropped mainly on the Sea of Japan side from Hokkaido to the San'in area. The Pacific side west of the Kanto region continues to be warmer than normal. On the 17th, temperatures dropped widely from Kanto to Kyushu due to cold air. In the Kanto region, there are many places where the temperature does not reach 10c during the day, and in western Japan, the temperature hovers just above 10c. On the 18th, temperatures rose nationwide due to southerly winds blowing toward a low pressure system. On Ishigaki Island, the Hikanzakura tree is in full bloom. On the 19th, as cold air moved southward, the cold returned to various places from the previous day, and the maximum temperature in central Tokyo was 11.1c. On the 20th, the cold weather eased somewhat in many places as the cold air moved northward. In Sendai, the flowering of Hakubai was announced. On the 21st, many places were covered in high pressure and sunny, and temperatures rose in many places. In Sapporo, the temperature rose to 7.9c, the warmest temperature of the season (as of February 21st).

1 month forecast: It will be warm nationwide at the beginning of March, and the cold will temporarily return in mid-March The trend of low rainfall on the Pacific side is likely to continue.

2026/02/26 23:32

On the 26th (Thursday), the Japan Meteorological Agency announced the latest monthly weather forecast for the next month.

Also, the whole country will be covered in warm air mainly at the beginning of the period.

Temperatures are expected to rise nationwide towards the beginning of March. In areas with heavy snowfall, the snow is expected to melt rapidly, so please be careful of avalanches and snow falling from roofs.
Also, in western and eastern Japan, when the weather gets sunny and the temperature rises, the amount of pollen scattered increases, so it will be essential to take thorough measures against hay fever.
From March 7th to March 13th, temperatures are expected to be near normal in many places, and in northern Japan, temperatures are expected to be near or below normal. The cold weather will return in mid-March, and the temperature difference is likely to increase. The second half of March will be near normal across the country, and the season will move toward spring.



Precipitation is expected to be near normal in northern to western Japan, and below normal in Okinawa and Amami. The weather changes periodically, and from around the 2nd to the 6th of the week, there will be areas that are susceptible to the effects of fronts and low pressure systems, resulting in heavy rain. However, it is not expected that the rainfall will be enough to overcome the low rainfall that has been occurring so far, and water shortages and dry weather are likely to continue. Please continue to conserve water as much as possible, and be careful when handling fire on days when the air is dry.

#Pressure distribution and waves
On the 15th, a low pressure system with a front moved eastward near the southern coast of Honshu and Hokkaido. At night, the wave height is 2 to 3 meters on the continental side of the central Japan Sea.
On the 16th, a low pressure system developed near the Chishima Islands, and the area around Japan became winter-like. North winds have strengthened, and wave heights are around 3m in wide areas of Japan.
On the 17th, a low pressure system off the coast of Kanto moved slowly eastward. Wave height around 3m near the Izu Islands.
From the 18th to the 19th, a low-pressure system west of Hokkaido developed and moved toward the waters near the Chishima Islands. From the night of the 18th to the 19th, waves exceeded 4 meters in height off the coast of the Noto Peninsula and west of Hokkaido, and on the night of the 19th, waves exceeded 6 meters in height off the coast of Sanriku.
From the 20th to the 21st, the area around Honshu was covered with high pressure, and the waves gradually became calmer.



#Sea surface temperature
Sea surface temperatures in the Japanese waters continued to be at normal levels.
The East China Sea remained in slightly high waters, while the waters near the Nansei Islands continued to be at normal levels.
South of Japan was at a normal level, and waters off the coast of the Tokai region continued to be slightly lower than normal.
East of Kanto, sea areas continue to be at normal levels.
The western part of the coast of Sanriku continued to be below normal, while the eastern part continued to be above normal.
The temperature off the southeast coast of Hokkaido was higher than normal, up to 3c higher.
Sea ice remained stagnant during this period in the waters around the Kuril Islands and the Sea of Okhotsk.

There will be a total lunar eclipse on March 3rd (Tuesday). What will the weather be like on that day

2026/02/26 13:55

A total lunar eclipse will occur next week on Tuesday night, March 3rd. This lunar eclipse is a phenomenon that can be seen throughout Japan at the same time, and occurs at times when it is easy to observe.
It begins to fade in the eastern sky at 18:50, and becomes a total eclipse at 20:04.
The total eclipse will end at 21:03, and the missing part will gradually become smaller, and the partial eclipse will end in the southeastern sky at 22:18.



As for the weather on Tuesday, March 3rd, clouds are likely to spread in many areas due to the influence of a low pressure system moving near the southern coast of Japan.
On that day, the weather is expected to deteriorate from the west, and there will be periods of rain from Okinawa to southern Tohoku. Depending on the time zone when the clouds spread, there is a possibility that there will be periods of sunshine in Okinawa, Kyushu, northern Tohoku, and Hokkaido.





However, March 3rd (Tuesday) is a little further away, so the forecast may change. Check the latest weather forecast.

A ``lunar eclipse'' is a phenomenon in which the full moon passes through the Earth's shadow, making it appear darker or eclipsed. A "total lunar eclipse" is a phenomenon in which the entire full moon, rather than just a portion of it, becomes dark.
The total eclipse of the moon appears reddish-black, a color known as ``red copper.''
This is the first total lunar eclipse that can be seen across Japan since September 8, 2025. The next total lunar eclipse to be seen across Japan will be on January 1, 2029.

Higher than normal weather expected through Saturday, 28th of the month Spring weather is in full swing in various places

2026/02/26 06:49

Today, the 26th (Thursday), there will be many places where the sun will reach during the day, and the weather will be as sunny as in March and April. On the other hand, on the Pacific side of the Kanto and Tohoku regions, winds blow from the north, so the temperature rises slowly and is likely to be typical of this time of year.

The predicted maximum temperature is Sapporo: 4c, Sendai: 7c, Tokyo: 13c, Nagoya: 19c, Kanazawa: 14c, Osaka: 17c, Kochi: 20c, Fukuoka: 18c.

In the Kanto and Tohoku regions, there is little sunlight, so it can feel cool during the day. Please stay warm.



From now on until the 28th (Saturday) of the month, temperatures will be high in various places, and the weather will be full of spring weather.
The maximum temperature in central Tokyo on Saturday the 28th is expected to be 19c, which is expected to be as warm as mid-April. In many other areas, the weather will be similar to late March to mid-April. Since the temperature can vary greatly throughout the day, it would be a good idea to choose clothes that are easy to adjust.
As the snow continues to melt in snowy areas, please continue to be careful of snow falling from roofs and avalanches.

As the month changes to March, low pressure systems and fronts are likely to pass through, and temperatures are likely to gradually return to normal.

Weather for today, the 26th (Thursday): The weather is improving in various places, but the sky looks like clouds are likely to spread in Kanto and other areas

2026/02/26 06:25

Today, the 26th (Thursday), the low pressure system and front that brought widespread rain yesterday (25th) are expected to move away to the east, and the area around Japan is expected to be covered by high pressure. The weather will improve in many places, but the sky is likely to be dominated by clouds in areas such as the Kanto region.



From Hokkaido to the Japan Sea side of Tohoku and Hokuriku, there are many places where the sun will reach and it will be sunny. Please continue to pay attention to melting snow in areas with heavy snowfall.

Moist northeast winds flow into the Pacific Ocean side of the southern Tohoku region and the Kanto region, so clouds tend to spread across the sky. There is a possibility of showers in the Tohoku region, so it is best to bring rain gear when going out.

Western Japan has periods of cloudy weather, but most of the time it will be sunny. It looks like the weather will be pleasant and sunny during the day, as warm as early April. In Kyushu, the rain spreads from late at night, so if you are returning late, it is best to bring rain gear.

Weather for the week Weather changes periodically over the next week Rain every few days

2026/02/25 13:05

From now on, until around Wednesday, March 4th next week, the weather will change periodically, and it looks like there will be many places where it rains every few days.

Today, the 25th (Wednesday), rain is falling over a wide area from Okinawa to Tohoku due to the influence of a front stationary on the southern coast of Honshu and a low pressure system moving eastward near Kyushu. Hokkaido is covered in high pressure and is mostly sunny.

After this, the front on the southern coast of Honshu will move south until the 26th (Thursday), and the weather will improve in many places, but there will still be some rain in the Kanto region until tomorrow morning.





The next day, on the 27th (Friday), rain will fall in central western Japan until the 28th (Saturday) due to the influence of a low pressure system forming near the East China Sea. On the Pacific side, there are likely to be some places in northern and eastern Japan where it will rain due to the influence of a low pressure system moving north off the coast of Sanriku.

On Sunday, March 1st, there will be high pressure from the north, and it will be sunny in many places.
On the 2nd (Monday) at the beginning of the week, the weather is likely to go downhill again from the west due to the influence of another low pressure system moving eastward from the continent. It looks like there will be widespread rain on the 3rd (Tuesday).

The rain is likely to be a blessing to the Pacific side of eastern Japan and western Japan, where there has been little precipitation so far, but it is likely that there will be localized areas near fronts and cyclone centers, so we need to be careful about how the rain falls.

Temperatures are expected to be higher than normal through early March. Especially from tomorrow until the 28th (Saturday), temperatures in many places will be similar to April.

Also, the amount of pollen scattered increases after rain. If you are sensitive to pollen, please check the latest information and take precautions such as wearing a mask and glasses when going out.

Widespread rain and snow, with some places experiencing heavy rain accompanied by thunder on the Pacific side of eastern and western Japan.

2026/02/25 09:49

A front extends from the eastern seaboard of Japan, through the southern coast of Honshu, Shikoku and Kyushu, and into the East China Sea.
Also, there is a low pressure area near Kyushu on the front that is moving east.

Currently, it is sunny in some parts of Hokkaido, but it is snowing and raining in Tohoku, it is raining widely in eastern and western Japan and the Okinawa region, and there are areas in Kyushu where storm warnings have been issued.





Today, the front will remain stationary on the southern coast of Honshu, and a low pressure system will move eastward above the front.
Rain will fall over a wide area from Okinawa to Tohoku, and there is a risk of heavy rain accompanied by thunder mainly on the Pacific side.
Also, when a low pressure system passes, the wind will become stronger, so be careful.

In the northern Tohoku region, there will be snow in some places, especially along the mountains.
It is expected to be sunny in many places in Hokkaido.
The daytime temperature will be lower than yesterday in many places, but it will be around normal or slightly higher.





Tomorrow, the front is expected to continue from the Tokai region to the Kanto region and extend into the southern seas of Japan, but it will move further south from today.
In the Kanto region, there are likely to be some areas where the front is near and it will rain, but in other areas, it will likely be sunny or cloudy.

The day after tomorrow, a low pressure system and a front are expected to approach from the west again.
As a result, there will be many places where it will rain.

Warm season forecast: Summer temperatures will rise nationwide

2026/02/24 16:37

The Japan Meteorological Agency today (Tuesday), the 24th, announced the ``warm weather forecast,'' which provides an outlook on the weather for the summer (June to August).
This summer, temperatures will be high nationwide as the country is likely to be covered in warm air. Rainfall in the summer and during the rainy season is expected to be near normal across the country.



There is a possibility that an El Nino phenomenon will occur this summer, and sea surface temperatures are expected to rise in the eastern to central equatorial Pacific Ocean. It is also expected to be low in the southeastern part of the tropical Indian Ocean. For this reason, cumulonimbus clouds will be more likely to occur near the international date line in the equatorial Pacific Ocean and over the sea east of the Philippines, but less likely to occur near Indonesia.
As a result of these effects, upper-level westerly winds are expected to flow southerly than normal over the Eurasian continent, but slightly northerly than normal near Japan. Although the Tibetan anticyclone's overhang to the north is weak, its overhang near Japan is likely to be about normal. Additionally, the Pacific anticyclone's overhang near Honshu will be somewhat strong, and its overhang south of Japan will be somewhat weak.
For this reason, the area around Japan is expected to be covered in warm air.



The average temperature in summer (June to August) is expected to be high nationwide.
Last summer was the third consecutive year of record high temperatures, breaking the record for the highest temperature in Japan. This summer is likely to be extremely hot again, so we need to be careful.

Precipitation is expected to be about normal in both summer (June to August) and the rainy season (June to July in northern, eastern and western Japan, and May to June in Okinawa and Amami).
Last year, the rainy season ended in June in many places, and eastern Japan experienced a record amount of sunshine. This year is likely to be about normal, but we need to be careful as there is a risk of heavy rain during the rainy season when the seasonal rain front becomes more active. Please check the latest weather information and prepare for heavy rain disasters.
