1-month forecast High temperatures expected nationwide West and East Japan have many cloudy and rainy days Expect water shortages to be resolved

2026/03/19 21:13

On the 19th (Thursday), the Japan Meteorological Agency announced the latest one-month forecast, which shows the weather outlook for the next month.



From now on, western and eastern Japan are expected to gradually experience a trough in atmospheric pressure, making them more susceptible to the effects of fronts and cyclones. Additionally, a low pressure system will be located in the north of Japan, and the cold air will be less likely to move south. As a result of these effects, warm southerly air heading toward low pressure systems and fronts will easily enter the Honshu area, and temperatures are expected to be higher than normal nationwide. The area around Okinawa and Amami will likely be covered by high pressure.



The Pacific side of western and eastern Japan will be susceptible to the effects of fronts and low pressure. Fronts are likely to form near Honshu, and the weather is likely to be more cloudy and rainy.
As a result, precipitation for the month will tend to be around normal or slightly higher than normal, mainly from the Pacific side of western Japan to eastern Japan. Rainfall has been low since mid-November last year, but the water shortage seems to be improving little by little. However, there is a possibility that the effects of light rain will remain in some areas, so caution is required in some areas.

On the 19th, it was announced that cherry blossoms would bloom in Tokyo and Hiroshima. All the locations where cherry blossoms have been announced so far are at least 5 days earlier than normal. As temperatures continue to rise across the country, cherry blossoms will begin to bloom at a rapid pace, and many places will reach their peak. As we enter April, it is likely that some places in western and eastern Japan will experience "summer days" with maximum temperatures of 25 C or higher.

2026/03/19 14:41

Today we will tell you the latest forecast for cherry blossom blooming in the Shikoku region in 2026.



Cherry blossoms bloomed in Kochi on March 16th, making it the top blooming cherry tree in Japan for
Someiyoshino.

In addition, cherry blossoms have bloomed in Nagoya, Gifu, and Kofu, and today, cherry blossoms bloomed in Tokyo.

In various places, the flowers are blooming about a week earlier than normal.
When will the flowers bloom in the Shikoku region




The next flowering area in the Shikoku region after Kochi is Matsuyama, which is predicted to be around March 22nd.

Next, the flowers will bloom in Takamatsu around March 24th, and in Tokushima around March 27th.
We think that Tokushima will bloom a day or two earlier than expected.



There are standards for cherry blossom blooming.
This is a specimen tree that is used by the Japan Meteorological Agency to monitor flowering conditions.
A state in which 5 to 6 flowers have bloomed is called flowering.
The tree is said to be in full bloom when more than 80% of the buds are open.
The number of days from flowering to full bloom depends on the weather and location, but on average it takes about a week.
It would be a good idea to plan for cherry blossom viewing from late March to early April.



However, it seems that there will be few good days for cherry blossom viewing in March.

Looking at the weather forecast for the next 10 days, it seems that the three-day weekend starting tomorrow from the vernal equinox will be sunny for a longer period of time than the first half of
.

On the last day of the holidays, the 22nd (Sunday), a low pressure system approaches from the west, and the weather is going downhill.
It will rain from the night of the 22nd (Sunday) to the morning of the 23rd (Monday).

Low pressure systems will continue to arrive periodically next week, bringing rain, so
there will be fewer cherry blossom viewing days under blue skies.

However, although it will be cloudy on the 24th (Tuesday),
we can expect clear skies,
and the sunny skies will continue around the 28th (Saturday) and 29th (Sunday),
so it would be a good idea to plan cherry blossom viewing around here.

However, the forecast may still change, so please check the latest information and enjoy cherry blossom viewing.

[Breaking News: Cherry Blossoms Blooming in Tokyo] Are there not many good days for cherry blossom viewing this year When is it recommended (Commentary: Weather forecaster Atsuko Miyake)

2026/03/19 14:09

Today, March 19th (Thursday) at 2:00 pm, it was announced that cherry blossoms have bloomed in Tokyo.
In Tokyo, the flowers bloomed 5 days earlier than normal and 5 days earlier than last year.
Including the locations where it has bloomed so far,
is blooming about a week earlier than normal.



Let's take a look at the flowering forecast for areas that have not yet bloomed.

It is expected that Hiroshima will bloom soon, on March 20th, the day of the vernal equinox.

Fukuoka is expected to arrive around the 20th or 21st.

The cherry blossom front is expected to bloom in Osaka around March 25th, and as the cherry blossom front moves north,
in Sendai, it is expected to bloom around April 3rd.
The cherry blossom front is likely to enter the Tohoku region and Michinoku soon in April.
It is around April 13th in Akita and around April 26th in Sapporo.

This year, it is likely that many places will bloom about a week earlier than normal or even earlier than normal.

The news about the cherry blossoms blooming continues to arrive, and
I am wondering when I can enjoy cherry blossom viewing.



From here on out, low pressure systems will arrive periodically,
and the weather will continue to be prone to rain until the middle of next week.

A low-pressure system will develop around the 23rd (Monday), so strong winds will blow that will blow away the flowers. However, the cherry blossoms, which have only recently bloomed, will not fall right away.

It looks like we can still enjoy cherry blossom viewing at the end of March.



As of 2:00 pm today, March 19th, the forecast is that there will be clear skies around the 24th (Tuesday),
and cherry blossom viewing will be enjoyable in western and eastern Japan.

From around the 25th (Wednesday), a low pressure system will pass near Honshu again, so the weather will continue to be prone to rain.
However, in western Japan, the next Saturday and Sunday,
28th (Sat) to 29th (Sun), will be sunny and you can enjoy cherry blossom viewing.

Eastern Japan will also be sunny around the 29th (Sunday), so you can enjoy cherry blossom viewing and cherry blossom viewing at night.

Today is a sunny day of spring from western Japan to eastern Japan, and temperatures remain high even during the three-day weekend.

2026/03/19 07:01

Today, the 19th (Thursday), it will be clear and sunny from western to eastern Japan, and temperatures will rise. It looks like it will be a warm day for this time of year, comparable to early to mid-April in many places. During the day, the weather will be relatively pleasant and sunny. In northern Japan, the temperature will rise slowly due to the influence of cold air in the upper atmosphere, and it will likely be colder than usual for this time of year.

The predicted maximum temperature in each region is Sapporo: 6c, Sendai: 15c, Tokyo: 19c, Nagoya: 18c, Kanazawa: 13c, Osaka: 17c, Kochi: 20c, Fukuoka: 16c.



On the 20th (Friday), the first day of tomorrow's three-day holiday, cold air is expected to flow into northern Japan, and temperatures are expected to reach normal levels in many places until the 21st (Saturday), but on the 22nd (Sunday), warm air will flow in from the south, causing temperatures to rise again in many places.
On the 22nd (Sunday), Sapporo is expected to have a maximum temperature of 11 degrees Celsius, which is likely to be the first double-digit temperature this year.
As the snow continues to melt in areas with heavy snowfall, it is important to be careful about snowmelt disasters.
Also, cherry blossoms were announced to bloom in Kochi, Gifu, and Kofu on the 17th, and in Nagoya on the 18th. The cherry blossoms will continue to grow this weekend, and it looks like there will be some places where you can receive news.
It would be a good idea to go see cherry blossoms during the three-day weekend.

Weather for today, the 19th (Thursday): Weather gradually improving from the west; rain in Kanto until morning

2026/03/19 06:25

Today, the 19th (Thursday), the low pressure system and front that brought rain over a wide area the previous day (18th) will gradually move away to the east of Japan, so the weather will improve in many places during the day, even if there is still rain in the morning.



Clouds tend to spread in Hokkaido due to the influence of cold air above, and there are likely to be places where it will snow or rain. Please pay attention to changes in the sky.

The sky in Tohoku is dominated by clouds on the Sea of Japan side. There will be some rain and snow until the morning, but it is expected to stop by the afternoon. Sunshine will reach the Pacific side.

Although there will be some areas of eastern and western Japan where the rain will remain until the morning, the weather will gradually improve and many areas will see sunshine in the afternoon. Please be aware that in the Kanto region, there is a risk of strong rain and wind during commuting hours. Also, please be careful not to leave your rain gear behind when you return.

Clouds tend to spread in Okinawa, and there are times when it rains, so please prepare rain gear when going out.

[Forecast for cherry blossom blooming in the Chugoku region] Will it be early this year When is cherry blossom viewing (Commentary: Weather forecaster Atsuko Miyake)

2026/03/18 14:16

Today we will tell you the latest forecast for cherry blossom blooming in the Kyushu region in 2026.



Yesterday, cherry blossoms bloomed in Nagoya.
Including the locations where it has bloomed so far,
is blooming about a week earlier than normal.
What will happen to the cherry blossoms in the Chugoku region


This year's cherry blossoms are expected to bloom earlier than normal in the Chugoku region.

The reason why the forecast is earlier than normal in the Chugoku region is that the temperature in February of this year was higher.



Let's take a look at the maximum temperatures since February 1 of this year compared to normal years at Hiroshima in Sanyo and Matsue in Sanin.

Temperatures were warmer than normal in Sanyo, especially from mid-to-late February, and even in Sanin, there were days when temperatures were 5 to 10 degrees Celsius above normal.

The cold weather returned in March, but the unusually warm weather in February seems to have helped the cherry blossom buds grow smoothly.
For this reason, we expect the flowers to bloom earlier than normal.



Let's take a look at the flowering forecasts for each region.

The earliest flowering area in the Chugoku region is predicted to be in Hiroshima on March 20th, the vernal equinox.

Next, Shimonoseki is expected to arrive around March 24th,
Matsue around March 26th, Tottori around March 27th, and Okayama around March 28th.
However, I think that Okayama will bloom a day or two earlier.



There are standards for the blooming of this cherry blossom.
This is a specimen tree that is used by the Japan Meteorological Agency to monitor flowering conditions.
A state in which 5 to 6 flowers have bloomed is called flowering.
Also, the same tree is said to be in full bloom when more than 80% of its buds are open.

The number of days from flowering to full bloom depends on the weather and location, but
on average it takes about a week.
It would be a good idea to plan for cherry blossom viewing from late March to early April.



Let's take a look at the detailed weather ahead.
There will be widespread rain this afternoon, followed by heavy rain tonight.
If you will be returning home late, please bring a large umbrella.

It looks like the rain will stop at dawn on the 19th (Thursday).
The weather will improve during the day tomorrow, with sunny skies returning.

On Friday the 20th, the vernal equinox, both the Sanyo and Sanin areas will be sunny, and the sun will feel warm during the day.

The clouds will increase towards the end of the three-day weekend, but the weather will not deteriorate.
The front will remain stationary in the first half of next week, making it cloudy and rainy.
However, the temperature will be high, and it will be warm enough to make the cherry blossom buds swell.

[Rain clouds spreading from the west] There are some places where the rain is getting stronger tonight. What will the weather be like for the 3-day weekend (Commentary: Weather forecaster Atsuko Miyake)

2026/03/18 14:01

The Pacific side of western and eastern Japan has been experiencing low rainfall since last fall.

Today, rain clouds are spreading from the west,
It looks like it will be a ``blessing rain'' for areas that have had little rain.



This is what the rain clouds look like at 11am.
There are rain clouds over western Japan due to low pressure and fronts.
However, there are no very well-developed rain clouds, and it is only a light rain of around 1mm per hour.



After this, it will start raining in the Kinki and Tokai regions in the evening, and
it will start raining in Hokuriku at night.

By the time the date changes, there are likely to be some places in Kyushu, Shikoku, and the Tokai region where
there will be heavy rain accompanied by thunder.
Please be careful of sudden rain, lightning, and gusts of wind.

When the date changes to tomorrow,
it will start raining in the Kanto and northern Tohoku regions, and
it is likely to snow in some places in the northern Tohoku region and high mountains.

There are likely to be some places where the rain peaks during the dark hours of the night.
However, the rain clouds that have developed are expected to move out to the eastern sea by tomorrow morning.



The low pressure system and front will move away from Honshu tomorrow night.
As the weather is covered by high pressure from the west, the weather is expected to improve from the west tomorrow.



Today, rain clouds will spread from the west,
It will rain from Kyushu to Tohoku.
In Shikoku, there is a risk of heavy rain accompanied by thunder late at night, so please be careful about how it rains.

Temperatures will be high even with rain,
Western and Eastern Japan will likely reach 15c to 20c.



The rain tomorrow will last until morning,
It will be sunny in many places during the day.
In Hokkaido and northern Tohoku, cold air will move in in the afternoon,
There are likely to be some places where it will snow or rain.

The warm air remains,
daytime tomorrow will be as warm as mid to late April.
Please wear clothes that are easy to put on and take off tomorrow.



Weekly weather.
For the three-day weekend starting on the 20th, the vernal equinox, the Pacific side is expected to be sunny for the first half of the day,
being covered by high pressure.
In the latter half of the holidays, the sun is likely to reach even the Sea of Japan side of northern Japan.

For the first half of next week, the front will remain stationary near Honshu,
and the weather will continue to be cloudy and rainy.

Heavy rain will occur over a wide area from today 18th (Wednesday) to tomorrow 19th (Thursday)

2026/03/18 12:52

Rain is expected to fall over a wide area from today, the 18th (Wednesday) to tomorrow, the 19th (Thursday), due to the effects of a low pressure system and front passing near Honshu.
After this, the high pressure system covering the area around Honshu will move to the east of Japan, and the low pressure system with a front from the East China Sea will approach the area around Kyushu. The area of rain will gradually spread from western Japan to eastern Japan and northern Japan.



Rain has already begun in some places in the Kyushu and Kinki regions. After this, the rain is expected to spread to the Tokai and Hokuriku regions by the afternoon of Wednesday the 18th, and rain and snow are expected to start falling in the Kanto and Tohoku regions late at night. Even in areas where it's not currently raining, it's safe to go out with an umbrella.



Please be aware that in the Kyushu, Shikoku, Kinki, and Tokai regions, from tonight until dawn on the 19th (Thursday), the rain will temporarily intensify as a front passes through, and it is likely that there will be some places with thunderstorms.



In the morning of tomorrow, Thursday the 19th, snow and rain will begin to fall in southern Hokkaido. In the Hokkaido region, another low-pressure system is approaching from the coastal region, and there will be snow and rain in some places in the afternoon, mainly on the Sea of Japan side.
Clouds tend to spread even on the Japan Sea side from Tohoku to Hokuriku, and there are some places where it will continue to rain or snow, but the weather will gradually improve in the afternoon.

The rain in western and eastern Japan is expected to stop by the afternoon of tomorrow, the 19th (Thursday).

In the Okinawa region, clouds will likely spread tomorrow (Thursday, the 19th) due to the influence of the front, and there will be some places where it will rain for a while.

[Kyushu Cherry Blossom Forecast] When will cherry blossoms bloom and be in full bloom this year (Commentary: Weather forecaster Atsuko Miyake)

2026/03/17 14:13

Yesterday, March 16th (Monday), cherry blossoms bloomed in Kochi, Gifu, and Kofu, and in Kofu, it was the earliest blooming in recorded history.
In various places, the flowers bloomed about a week earlier than normal.



This year, the Kyushu region is also expected to bloom at a normal level and earlier than normal.

The reason for the forecast being earlier than normal is that
the temperature was higher this February.

Let's take a look at the highest temperatures in Fukuoka and Kagoshima as representative locations in Kyushu since February 1 of this year compared to normal.



It was especially warm from mid-February to late February,
There were days when the temperature was 5 to 10 degrees Celsius higher than normal.

Although the cold weather returned in March, the warmth of February seems to have helped the cherry blossom buds grow smoothly.
For this reason, we expect the flowers to bloom earlier than normal.




Now, let's take a look at the flowering forecast for each region.
The earliest place in the Kyushu region that is predicted to bloom is March 20th, the spring equinox in Fukuoka.
Next, the flowers are expected to bloom in Nagasaki on March 21st,
Miyazaki, Kumamoto and Saga around March 22nd,
Oita around March 25th, and Kagoshima around March 26th.

There are standards for this cherry blossom blooming.
This is a specimen tree that is used by the Japan Meteorological Agency to monitor flowering conditions.
A state in which 5 to 6 flowers have bloomed is called flowering.
The tree is said to be in full bloom when more than 80% of the buds are open.

The number of days from flowering to full bloom is about one week, depending on the weather and location.

From now on, the temperature is going to be high, and the cherry blossom buds are going to swell all at once.




Let's take a look at the future weather in the Kyushu region.

Today, the 17th (Tuesday), it will be sunny, but tomorrow, the 18th (Wednesday), a low pressure system and a front will pass and there will be widespread rain.
It looks like there will be heavy rain in some places, accompanied by thunder.
The rain is likely to stop on the afternoon of the 19th (Thursday).

The spring equinox on the 20th (Friday) is expected to be broadly sunny and
with a maximum temperature of around 20c.

Although there will be more clouds towards the end of the three-day weekend,
temperatures will be on the higher side, and news of cherry blossoms blooming will continue to arrive.

Severe drowning in the south of Japan due to low pressure [Ocean summary (March 8-14, 2026)]

2026/03/17 12:43

Due to the effects of two low-pressure systems near Ogasawara, waves were high in a wide area on the Pacific side, and there were areas in the east of Japan that were heavily flooded and areas in the south of Japan that were severely flooded.
The following is a summary of the ocean (March 8-14, 2026).



#Pressure distribution and waves
On the 8th, the pressure distribution near Japan was high in the west and low in the east, and waves were high in a wide area around Japan.
On the 9th, the pressure pattern of high in the west and low in the east loosened from the west, and waves in the sea near Japan remained calm at night.
On the 10th, a low pressure system accompanied by a front developed and moved eastward east of Japan. From the 11th to the 12th, this low pressure system slowed down east of Japan.
To the east of Japan, the sea area with high waves gradually expanded, and the area of barges around the low pressure area also expanded.
On the 13th, a low pressure system with a front moved eastward south of Japan, and another low pressure system moved northeast east of the Kuril Islands.
The gradient in atmospheric pressure between these low pressure systems and the continental high pressure system increased, causing waves to rise in the seas near Japan.
On the 14th, two low-pressure systems near Ogasawara caused high waves across the Pacific Ocean.
There was a sea area in the east of Japan that was heavily flooded, and in the south of Japan that was severely flooded.



#Sea surface temperature
Sea surface temperatures in the Japanese waters expanded to areas where they were higher than normal in the northern and western regions.
The East China Sea continued to be slightly higher than normal.
The waters around the Nansei Islands continued to be at normal levels.
The southern part of Japan is at normal levels, and off the coast of the Tokai region, areas slightly lower than normal have expanded.
The sea area from the east of Kanto to the southern part of the coast of Sanriku continued to be significantly warmer than normal, with temperatures up to 4 C higher than normal.
The northern Sanriku coast, the southeastern coast of Hokkaido, the waters around the Chishima Islands, and the Sea of Okhotsk were at normal levels, but the sea ice area gradually expanded in the waters near the Chishima Islands and the Sea of Okhotsk.
