[Breaking news] Rainy season ends in Shikoku region; beware of intense heat

2026/07/12 12:19

Today, the 12th, the
meteorological observatory announced that the rainy season appears to have ended in the Shikoku region.

Shikoku region: Around July 12th (5 days earlier than normal)

*The announcement of the end of the rainy season is preliminary. It may be revisited and revised in the fall.

Today, the Shikoku region is covered by the Pacific anticyclone and is mostly sunny. In Takamatsu City, Kagawa Prefecture, the temperature was 33.6 degrees Celsius by 12:00, making it extremely hot as the rainy season ends.



For this reason, heat stroke warning alerts have been announced in multiple regions in western Japan.



For the next week, the Shikoku region is expected to be covered by the Pacific anticyclone and have many sunny days.



The middle of the week is expected to be particularly hot, with maximum daytime temperatures exceeding body temperature. Please take care of your health.

High temperatures will continue in eastern and western Japan from now until around the 18th. Be careful of heatstroke.

2026/07/12 06:33

On the 11th, the Japan Meteorological Agency announced general weather commentary regarding high temperatures.

From around the 14th (Tuesday) to the 18th (Saturday) in eastern Japan, and around the 18th (Saturday) in western Japan, there will be days covered by high pressure and warm air, so it is expected that there will be some extremely hot days with maximum temperatures of 35 degrees Celsius or higher.
Please take care of your health, such as preventing heat stroke, and managing your crops and livestock.



Looking at the forecast for the maximum temperature for the next week, it looks like Fukuoka Prefecture will continue to experience extremely hot days with temperatures above 35c until around Wednesday the 15th. There will also be days when the temperature is 38 C or 37 C, which is higher than your body temperature, so it is essential to take precautions against heatstroke.
Tokyo, Nagoya, and Osaka will initially experience midsummer days with temperatures above 30c, and from around the 14th (Tuesday) it is expected to become an extremely hot day with temperatures above 35c.
Especially in Tokyo, the temperature will rise from 30 degrees Celsius on the 13th (Monday) to 37 degrees Celsius on the 14th (Tuesday), rising by 7 degrees Celsius over the next day, so the temperature will rise rapidly as the body is still not used to the heat.
Please take precautions against the heat by staying hydrated frequently and using the air conditioner appropriately when indoors.

Also, please check the "Heatstroke Warning Alert" issued jointly by the Japan Meteorological Agency and the Ministry of the Environment, and consider refraining from outdoor activities as much as possible on the days that are announced in the target area.

[Next week will be a very hot day] Tokyo is expected to reach 36 degrees Celsius, and Nagoya is expected to reach 38 degrees Celsius every day. Beware of heatstroke! (Commentary: Weather forecaster Atsuko Miyake)

2026/07/10 15:14

One of the strongest typhoons approaching the Japanese archipelago this year is currently approaching the Okinawa region.



Typhoon No.9 is now a large and extremely powerful force.
It is located on the sea south-southeast of Miyakojima and is moving northwest at 20km/h.
The maximum instantaneous wind speed near the center is 60M.

A typhoon is expected to approach Okinawa's Sakishima Islands tomorrow (Saturday) morning, bringing with it fierce winds that could destroy some houses.
For more information about Typhoon No. 9, please also check out our YouTube Okinawa channel, where we talk about it in detail.

As a result of the indirect effects of this typhoon, high pressure is strengthening near Honshu.



This is the forecast weather map for tonight.
The area around this area is expected to be covered in high pressure and have many sunny skies into tonight.
The weather is sunny and the temperature is rising during the day.



Looking at the maximum temperature until noon, the temperature in Dazaifu City, Fukuoka Prefecture has risen to 36.0c, making it an extremely hot day since the morning.

In addition, today's temperature was 35.9c in Hita City, Oita Prefecture, making it the third consecutive day of extreme heat.



Furthermore, it looks like the heat will be severe tomorrow and the day after.
Temperatures will rise, especially in Kyushu.
This is because a high pressure system is coming directly over Kyushu.
Fukuoka is expected to experience extremely hot days tomorrow, the 11th (Saturday) at 37 degrees Celsius, and the 12th (Sunday) at 38 degrees Celsius.

Also, there are likely to be some extremely hot days, especially in the inland areas of western and eastern Japan.



At this time of year, people are not yet used to the heat, so be careful of heat stroke.
Try to stay hydrated even if you're not thirsty.
Also, when you sweat a lot, make sure to take in a moderate amount of salt.
Please do not put up with the heat and use the air conditioner.



This heat brings sudden changes in the weather.

After this, let's take a look at the rain clouds.
Rain clouds are expected to develop along the mountains near Honshu into today's evening.
It rains widely during the day in Hokkaido, but it seems that the rain will stop in many places at night.

However, tomorrow (Saturday), cold air will flow into the upper air.
Moist air will also flow in around the edge of the large high-pressure system,
which will make the atmospheric conditions unstable in northern Japan tomorrow.

Especially in the afternoon when the temperature rises, heavy rain is likely to turn into thunderstorms in some places.
Please be careful of sudden heavy rain, lightning strikes, and gusts of wind in northern Japan and Hokuriku.



Saturday and Sunday weather.
First of all, the Sakishima Islands in Okinawa will experience very stormy weather as the typhoon approaches.
Please be on guard for strong winds, high waves, and heavy rain into tomorrow (Saturday).
Flooding may occur in coastal areas due to storm surges and high waves.

It will be extremely hot in Kyushu this Saturday and Sunday. Please be extremely careful about heat stroke.
Also, although there are parts of western and eastern Japan that experience sunny skies, please be careful of sudden changes in weather along the mountains.
There will be rain and thunderstorms in northern Japan and Hokuriku.
Please be careful of lightning, gusts of wind, and hail.



Weekly forecast. Next week, the heat will become severe even in eastern Japan.
Especially on the 14th (Tuesday), the temperature in Tokyo is expected to be 36c.
In Nagoya, temperatures are expected to reach 38 degrees Celsius on the 14th (Tuesday) and 15th (Wednesday), and depending on the location, it is likely to be a "severely hot day" of 40 degrees Celsius or higher.
Please be even more careful about heat stroke next week.
