Weekly weather: After the weather improves, be careful of cedar pollen scattering; weather is expected to deteriorate nationwide on the weekend

2026/03/02 13:09

From this weekend (Saturday) onwards, there is a possibility that the weather will deteriorate again across the country.



Tomorrow, the 3rd (Tuesday) and 4th (Wednesday), due to the influence of a low pressure system on the south coast, northern and eastern Japan will experience cold rain and snow, and there will be localized areas of heavy snow along the mountains and inland. There is a possibility of snow accumulating in some areas even on the plains, so please be careful of deteriorating road conditions. From the 3rd (Tuesday) to the 4th (Wednesday), northern and eastern Japan will experience a temporary return to cold weather, with daytime temperatures not rising much and making it feel colder. Meanwhile, the weather in western Japan is expected to improve on the 4th (Wednesday) and bring spring warmth.

On the 5th (Thursday), it will likely snow in some places in Hokkaido, but the weather is expected to improve from Tohoku to Kanto-Koshin and Hokuriku. However, after the weather improves, the amount of cedar pollen scattered tends to increase. There are some places where cedar pollen has already reached its peak, so those who are sensitive should take precautions.

Around Friday the 6th, a new front and low pressure system will approach from the west, and the weather is expected to deteriorate again from the west. The low pressure system will then continue to develop as it moves through the Sea of Japan, and is expected to pass through northern Japan around Monday the 9th of next week. On Saturday the 7th, it will rain across the country, and there will be some places in northern Japan where it will snow. Especially in Hokkaido, there is a possibility that the effects of the low pressure system will continue to bring snow and strong winds, resulting in rough weather, so please pay close attention to the latest weather information that will be updated in the future.

2026/03/02 07:34

Today, the 2nd (Monday), a low pressure system and front are approaching from the East China Sea. Developed rain clouds associated with low pressure and fronts are approaching from the west, and it is already raining in some places in Kyushu and the Nansei Islands.



The low pressure system accompanied by the front is expected to move along the southern coast of Honshu, and the rain will gradually spread over western Japan. In southern Kyushu and Okinawa, please be careful of heavy rain accompanied by thunder from noon to evening. In Chugoku, Shikoku, and Kinki, the weather will gradually change to rain from the afternoon. It is likely that there will be places in the Tokai and Kanto regions where it will start raining late at night.



Tomorrow, the 3rd, the low pressure system will continue to move along the southern coast of Honshu. From early morning until noon on the Pacific side of western Japan, be careful of heavy rain accompanied by thunder in Shikoku and the Kii Peninsula. From Kanto-Koshin to the southern part of Tohoku, there will be freezing rain and snow, and there are likely to be some places along the mountains and inland where the snow will be heavier. Because the low-pressure system is moving eastward relatively slowly, cold rain and snow are expected to continue for a long period of time from northern to eastern Japan into the 4th (Wednesday).



In particular, in northern and eastern Japan, snowfall will be heavier in localized areas, especially inland and along mountains. The snow is expected to spread to the plains, and if the snow continues to fall, there is a risk that snow will accumulate even in the plains of the Kanto region. From the 3rd tomorrow to the 4th, please be careful of deteriorating road conditions and snow accumulation.

Weekly Weather Will you be able to see the total lunar eclipse on the 3rd (Tuesday)

2026/03/01 12:38

Today, the 1st (Sunday), a low pressure system is moving northward east of Hokkaido, and a high pressure system is protruding from the continent. In northern Japan, there is a large gradient in atmospheric pressure and winds are increasing. Also, in some parts of Hokkaido, it is snowing.
The area around Honshu is covered by an anticyclone that extends from the continent, and there are many places where it is sunny. In the Okinawa region, there will be some places where it will rain due to the humid air.

Tomorrow, the 2nd (Monday), a low pressure front will form near the East China Sea and move eastward, so the weather will deteriorate from the west. Rain is expected to start falling around noon in Kyushu and gradually spread over the area. It will start raining in China and Shikoku at night.
Eastern and northern Japan will have many sunny days, but the Kanto region will be affected by humid air and will have many clouds, and there will be some areas where it may rain. There will be places on the Sea of Okhotsk side of Hokkaido where it will snow.



On the 3rd (Tuesday), a low pressure system will move eastward along the southern coast of Honshu, and the area of rain will spread from Kinki to southern Tohoku. Clouds are likely to prevail from northern Tohoku to Hokkaido as well.

On the 4th (Wednesday), the weather will improve in western Japan, and there will be some lingering rain in the Tokai and Tohoku regions. As the low pressure passes, the temperature will drop and the winter cold will likely return, so please take care of your health.

On the 5th (Thursday), many places near Japan will be covered in high pressure and it will be sunny.
From the 6th (Friday), the low pressure system will move toward the Sea of Japan and pass near northern Japan until the 8th (Sunday), so the weather is likely to go downhill again from the west.



Now, regarding the time of the total lunar eclipse on the 3rd (Tuesday), clouds are likely to spread over a wide area due to the influence of a low pressure system moving eastward.
Unfortunately, there is a possibility of rain in China, Kinki and southern Tohoku. On the other hand, we can expect periods of sunshine in Okinawa to Kyushu and parts of northern Japan, which are behind the low pressure system.



This total lunar eclipse will be observed at a time when it is easy to observe.It will begin to eclipse in the eastern sky at 18:50, become a total eclipse from 20:04 to 21:03, and then the eclipsed portion will gradually become smaller, until the partial eclipse ends in the southeastern sky at 22:18.
The total eclipse of the moon appears reddish-black, a color known as ``red copper.''
The total lunar eclipse lasts about an hour, so it might be a good idea to aim for a gap in the clouds for a chance.
Forecasts are still subject to change, so check back for the latest information.

Today is a pleasant and sunny day in eastern and western Japan.Hinamatsuri will be as cold as January in the Kanto region.

2026/03/01 07:02

Today, the first day of the month, cold air will flow mainly into northern Japan, so there will be many places in northern Japan where the temperature will be lower than the day before, and many places will experience temperatures typical of this time of year. The air seems to feel cool even during the day.

Although there are some places in eastern and western Japan where the temperature will drop from the previous day, there will be places in western Japan where the temperature will be the same as yesterday or even higher. In many places, the temperature during the day exceeds 15 degrees Celsius, so you won't need a jacket during the day to enjoy the cheerful weather.
Since the temperature difference between morning and evening and during the day is large, it would be a good idea to choose clothes that are easy to adjust.

The predicted maximum temperature is Sapporo 1c, Sendai 11c, Tokyo 18c, Nagoya 19c, Kanazawa 12c, Osaka 17c, Kochi 18c, and Fukuoka 17c.



Next week, low pressure and high pressure will alternately pass near Japan, and the weather is expected to change periodically. It's going to be a week where we need to be careful about changes in temperature, as there will be times when cold air will temporarily move south.
In central Tokyo, a low pressure system will pass through the Doll's Festival on the 3rd (Tuesday), and rain is expected. The temperature is not expected to rise, and the forecast high temperature is 9 degrees Celsius, which is expected to be as cold as mid-January. There will be a big difference in temperature from the day before, so please be careful not to get sick.

After the 4th, temperatures across the country are likely to settle down to normal. As the snow continues to melt, please be careful of snow melting disasters in areas with heavy snowfall.

Today's weather (Sunday): Widespread clear skies. Be careful of pollen scattering.

2026/03/01 06:23

Today, the 1st (Sunday), the start of March, will be sunny in many places as the area around Japan will be covered in high pressure. You need to be careful about pollen scattering especially in sunny areas.



On the Japan Sea side of northern Japan, clouds will likely spread mainly in the morning. It looks like there will be some sunshine in the afternoon. It looks like it will be sunny and blue skies on the Pacific side.

It will be sunny and sunny from eastern to western Japan. It looks like it's going to be a nice day to spend the day and go out. In sunny areas, pollen is expected to scatter, so if you suffer from hay fever, please take precautions.

The sky in Okinawa is dominated by clouds. There is a possibility of rain showers after the evening, so it is a good idea to bring a foldable umbrella with you when going out.

What do you call a day when the maximum temperature is 40c or higher "Hot day" "Super hot day" The Japan Meteorological Agency conducts a survey

2026/02/28 12:36

The Japan Meteorological Agency announced on Friday, February 27th that it will conduct a survey regarding the names of days when the maximum temperature is 40c or higher. Anyone can answer the
survey once, and the format is to select one of 13 possible names, such as "scorching hot day," "extremely hot day," "super hot day," or to write a proposed name in the free text field.
The Japan Meteorological Agency will decide based on the survey results as well as the results of interviews with experts and Japanese language experts.

Currently, days with a maximum temperature of 25 C or higher are defined as "summer days," days with a maximum temperature of 30 C or higher as "midsummer days," and days with a maximum temperature of 35 C or higher as "extremely hot days." These days are used in weather forecasts, etc., but there is no term yet for days with a maximum temperature of 40 C or higher.



In recent years, remarkable high temperatures have been recorded in summer for three consecutive years, and temperatures exceeding 40c have been observed almost every year.
Last year, daily maximum temperatures of 40c or higher were observed at 30 locations across the country. In addition, the highest temperature recorded was 41.8c on August 5th in Isesaki, Gunma Prefecture, 41.4c on August 6th in Shizuoka Prefecture, and 41.4c on August 5th in Hatoyama, Saitama Prefecture.

The summer weather forecast released by the Japan Meteorological Agency this week predicts that average temperatures will be higher than normal across the country. It looks like it will be extremely hot again this year.
Why not take the survey and be aware of how to deal with the dangerous heat

The survey will be conducted on the Japan Meteorological Agency website from February 27th (Friday) to March 29th (Sunday).

[Latest Weekly Weather] Calm weather to start March.Total lunar eclipse on the 3rd (Tuesday) Hinamatsuri.Where can you see it

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.
