Be careful of heatstroke even in June! Prevention methods you should start right away

2026/06/26 17:50

The rainy season has begun nationwide, and it is easy to think that summer is not yet in full swing. However, June is a time when you need to be careful as the risk of heat stroke gradually increases. We will explain in an easy-to-understand manner the risks of heatstroke that lurk in June and the prevention methods you should start right away.

When you think of heatstroke, you may think of midsummer, but June is also a time when heatstroke is likely to occur, as the high humidity during the rainy season and rising temperatures coincide. Because the body is not yet accustomed to the heat, the ability to sweat and regulate body temperature is insufficient, and heat tends to accumulate in the body. Furthermore, the humidity is extremely high during the rainy season, making it difficult for sweat to evaporate. Additionally, awareness of heatstroke prevention is still low in June, and frequent hydration and dressing changes tend to be put off. As a result, there is a risk that dehydration will progress without you noticing, leading to poor health.
In this way, June is a time when you need to be careful about heat stroke, when the three factors of temperature, humidity, and being cautious are all present.

If you recognize heatstroke in its early stages and take appropriate measures, you have a higher chance of preventing it from becoming more serious. Early signs include dizziness, lightheadedness, convulsions, and unusual sweating. In the early stages, patients often do not notice any abnormalities, and elderly people and children in particular may not be able to communicate their symptoms well. It is also important for those around you to notice any abnormalities early on to prevent heat stroke.

Don't let your guard down even during the rainy season. June, when the humidity is high and the temperature starts to rise, is the perfect time to start taking measures to prevent heat stroke. We will introduce recommended prevention methods.
The first thing to do is to maintain a comfortable indoor environment by making good use of air conditioners, dehumidifiers, and fans. As the term "indoor heatstroke" suggests, if you do not use the air conditioner, you may suffer from heatstroke even at home. Especially during the rainy season, the humidity is high, making it difficult for sweat to evaporate, making it difficult for your body temperature to drop.
The second thing is frequent hydration. By the time you feel thirsty, you may already be dehydrated. Make sure to drink plenty of water throughout the day, even if you're not thirsty.
Thirdly, when you go out, use a parasol or hat to avoid direct sunlight. It has been reported that the temperature under a parasol is 2 to 5 degrees Celsius lower than in the sun. Additionally, wearing a hat can lower the perceived temperature by up to -10c.

June is a time when high humidity due to the rainy season and rising temperatures combine to cause heatstroke. It is important to take early measures and not be careless and think, ``It's not summer yet, so it's okay.'' Before the real heat hits, let's get through the summer in good health by incorporating some measures that we can easily do into our daily lives.

[Kanto] Tropical cyclone (Typhoon No. 8) approaches in the morning of the 27th (Saturday), and Typhoon No. 7 approaches in the evening, affecting transportation (commentary: Weather forecaster Atsuko Miyake)

2026/06/25 15:01

Heavy rain is likely to continue for a long time in the Kanto region from now until the 27th (Saturday) due to the rainy season front and two typhoons.
Please be aware that transportation may be affected.


The rainy season front is expected to remain near the Kanto region into tonight.
In addition, both typhoons No. 7 and No. 8 are expected to move northward from the southern sea. The extremely warm and humid air around the
typhoon flows into the front, increasing the activity of the
front.



First, let's look at the information on the approaching Typhoon No.8.
Typhoon No. 8 is expected to continue moving north without intensifying much.

It is expected to turn into a tropical cyclone off the coast of the Tokai region on the morning of the 27th (Saturday).

However, even if it turns into a tropical cyclone, very warm and humid air will flow towards the seasonal rain front that is stationary near the Kanto region, which will continue to stimulate the front.
Even after it becomes a tropical cyclone, it will bring heavy rain, so we cannot let our guard down.



Next, let's look at the information on Typhoon No.7.
After this, it is expected to approach Okinawa and Amami by tomorrow (Friday), accompanied by stormy winds.

After that, the storm area will disappear, but it is expected to quickly move across the Pacific side of western and eastern Japan.
It is expected to be closest to the Kanto region on the night of the 27th (Saturday).

However, this forecast may still change, so please continue to pay attention to the latest information.



Rain and wind forecast.
Let's take a look from midnight on the 27th (Saturday), when the rain and wind will be strongest in the Kanto region.

Rain is expected to fall widely in the Kanto region, and active rain clouds are expected to cover the Kanto region in the morning due to a tropical depression that will change from Typhoon No.8.

Shinkansen and expressways also run in the Tokai and Kanto regions, which are subject to active rain clouds.
Heavy rain and strong winds may affect transportation.



The rain will weaken temporarily in the afternoon, but then from evening to night, the rain clouds of
Typhoon No. 7 will approach. It looks like the rain and wind will become stronger again.

Rain clouds will move east towards the end of the night, but over the next three days, around 400mm of rain is expected to fall in most parts of the Kanto region.
It looks like it's going to rain quite a bit.
At this time of year, the amount of rain that falls in a month's worth is well in excess of the amount of rain that falls in one month, increasing the risk of heavy rain disasters.



Please be careful of landslides and river flooding.
If heavy rain falls in urban areas, there is a risk of large-scale flooding.
When it is raining heavily, please avoid going near underpasses.

In addition, transportation may be significantly affected on Saturdays and Sundays.
Please continue to pay attention to the latest traffic information.



, we will look at the detailed weather of each place.
It is expected that there will be heavy rain across the Kanto region until the 27th (Saturday).
Please continue to pay attention to the latest information.
And on the 28th (Sunday), the rain will stop in many places.
After that, the rainy season front will likely stay near Honshu, so
the weather will continue to be cloudy and rainy.

[Double typhoon + rainy season front] Be wary of heavy rain disasters due to long rain accumulation! (Commentary: Weather forecaster Atsuko Miyake)

2026/06/25 14:06

Heavy rain is expected to continue from now until the weekend as the rainy season front and two typhoons approach.
Please be careful of heavy rain disasters caused by long rain accumulation.



First, let's look at the amount of rain so far.
The rainy season front has been stationary and it has been raining for a long time.

The amount of rain is particularly high in Kyushu,
over the past 72 hours, more than 400 to 500 mm of rain has fallen in Nagasaki Prefecture.
All of these values have been updated to the highest in June, and this is record-breaking heavy rain.

A typhoon approaches where the ground has already become loose due to heavy rain.



Let's take a look at tonight's forecast weather map.
