Today the 31st (Sunday) Future weather: Kyushu to Kanto has a lot of clouds mainly on the Pacific side; Okinawa is also affected by Typhoon No.6

2026/05/31 12:44

In the afternoon of today, the 31st (Sunday), clouds are likely to remain from Kyushu to Kanto as far as the Pacific Ocean side. From Hokuriku to Kyushu, the maximum temperature will be 30 degrees Celsius or higher in many midsummer days. The area around Honshu will be gently covered by high pressure, but Typhoon No. 6 is expected to move northward south of Okinawa.



From Kyushu to Kanto, clouds are likely to increase on the Pacific side until evening. There may be rain and thunderstorms in some parts of the Kanto-Koshin region, including along the mountains, after the evening.
I think some people will be enjoying some leisure time in the mountains today on Sunday. Please pay close attention to changes in the sky. If you notice signs such as approaching black clouds, sudden strong winds, or hearing thunder, evacuate inside a building or somewhere safe.



On the other hand, it looks like the Chugoku region and Hokuriku will be clear and sunny. The wind is calm and it is expected to be a good day for washing clothes.
Also, Tohoku and Hokkaido are likely to have stable clear skies in the afternoon.
Okinawa has a lot of clouds, and there will be rain and thunderstorms here and there. At sea, swells from Typhoon No. 6 are expected to build up gradually.



Typhoon No. 6 is developing in the south of Okinawa and moving north. It is likely that there will be heavy rain in Okinawa and Amami from tomorrow June 1st (Monday) to June 2nd (Tuesday). It is better to prepare for a typhoon today.



Today, the 31st (Sunday), the heat will continue, hard to believe it is the last day of May.
From Hokuriku and Kanto to Kyushu, there are many midsummer days with temperatures above 30 degrees, so you need to be careful about heatstroke.
It is expected to be 30c in Tokyo, 31c in Osaka, and 32c in Nagoya.
As the unusually hot weather continues, please make sure to drink plenty of water and take adequate breaks.
The temperature in Sapporo is 25c, higher than yesterday, and it will be as sunny as mid-July. Please be careful not to get sick due to the sudden heat.

[Typhoon No. 6] Before the stormy weather, you should know how to use Kikikuru

2026/05/31 12:08

Typhoon No. 6 is moving north-northwest south of Okinawa.
There is a possibility that it will approach the Okinawa and Amami regions with strong winds and strong winds from June 1st to 2nd, and then approach from western Japan to eastern Japan around the 3rd.

Even if the typhoon itself is far away, the rain can suddenly intensify due to the influence of humid air, and the outside situation can change dramatically in a short period of time.



To understand the disaster risk in your area, please use the Kikikuru (risk distribution) provided by the Japan Meteorological Agency.



In Kikikuru, the risk level of landslides, inundation, and floods is color-coded, and you can check where the danger is currently high on the map using the colors.



Color is a guide for evacuation actions.

Black: Your life is in danger. Ensure safety immediately!
Purple: Evacuate everyone from dangerous areas
Red: Those who will take time to evacuate
(elderly people, people with small children, etc.)
evacuate early.
Yellow: Check the evacuation site, evacuation route, and timing

In particular, if a purple or black sign is displayed,
you must prioritize ensuring your safety, regardless of whether there is an evacuation order from the local government.



As the surrounding situation becomes difficult to understand at night, it is important to take early evacuation actions before the danger level increases. Additionally, as a typhoon approaches, there is a risk of flying objects caused by the strong winds, so please take precautions such as clearing things from your balcony and reinforcing your windows.


Typhoon No.6's course and strength may change in the future. Please stay safe while frequently checking announcements from the Japan Meteorological Agency, information from local governments, Kikikuru and typhoon information. In order to protect yourself, your family, and those around you, please prepare early and behave calmly.

If you are planning to go out, please consider taking action early or reconsidering your plans.

2026/05/31 06:31

Today, the 31st (Sunday), the area around Honshu will be covered in high pressure, but due to the effects of a trough of pressure, the sky is likely to be cloudy mainly on the Pacific side. There will be many sunny places on the Sea of Japan side. Okinawa needs to be careful of high waves caused by Typhoon No.6.



It will be sunny and blue skies will spread across the Japan Sea side of northern, eastern and western Japan. On the other hand, skies on the Pacific side are likely to be cloudy mainly in the morning. However, the weather will gradually return to sunny skies in the afternoon, so it looks like the weather will be fine for going out.

Temperatures are high in many places, similar to late July to late August. It looks like there will be some extremely hot days in Kyushu. If you are active outdoors, please take precautions against heat stroke.

Due to the influence of fronts, clouds tend to spread in Okinawa, and there will be places where it will rain. It's safe to have rain gear when going out.
In the Nansei Islands, waves are expected to gradually increase due to the effects of Typhoon No. 6, and there are expected to be some places where there will be barges at night. The wind will also be strong, so please be careful of high waves and strong winds. The typhoon will be approaching from tomorrow 1st onward, so be sure to prepare today.

Typhoon No. 6 is expected to approach western Japan with strong winds from the 2nd (Tuesday) to the morning of the 3rd (Wednesday), and to approach eastern Japan from the afternoon of the 3rd (Wednesday) to the 4th (Thursday).
A front is expected to extend to the east of the typhoon, and warm, humid air from the tropics is expected to flow toward the front. As the front becomes more active, it is likely that there will be heavy rain in some places even before the typhoon approaches.



In the Okinawa region, please take early typhoon countermeasures, refrain from going out unless necessary, and stay away from windows when indoors, and take strict precautions against strong winds.
From the 1st (Monday) to the 2nd (Tuesday), active rain clouds from the typhoon will form, and there is a risk of warning-level heavy rain. Please be extremely cautious of landslides, flooding of low-lying areas, and rising and flooding rivers.

after this, it is expected to move northward as it passes through the warm sea surface.


In particular, it is expected to become a "strong force" and increase to 970hPa on the 31st (Sunday).
Then, it continues to develop and moves south of Okinawa, dropping the central pressure to 960hPa on
1st (Monday).

It is expected to maintain its strong strength and approach the Okinawa region over the 2nd.
