The summer Pacific high pressure system will become more powerful towards the end of the week, and the heat will become severe in western and eastern Japan. The temperature is expected to rise to around 35 degrees Celsius in some places this weekend, so it is essential to take precautions against heat stroke.



The Pacific anticyclone is expected to gradually strengthen from today, the 6th (Monday) onwards. In the first half of the week, it is expected to spread its influence from Okinawa to western Japan, pushing the seasonal rain front northward.
From tomorrow, the 7th (Tuesday) onward, high pressure will begin to cover eastern Japan, and the second half of the week will see a wide range of sunny spells during the rainy season.

Looking at the maximum temperatures in various places, Fukuoka and Osaka cities are expected to experience midsummer days with temperatures above 30c starting tomorrow, the 7th (Tuesday).

On the 24th, extremely warm and humid air flowed in, and at 8:48 a.m., it was announced that a linear rain band had formed near the Satsuma region of Kagoshima Prefecture, and a level 4 landslide danger warning was announced for the Satsuma region. On the 25th, a level 4 flood warning was announced for the upper reaches of the Yamakuni River in Oita Prefecture due to the inflow of extremely warm and humid air. Active rain clouds continue to hang over a wide area of western Japan, from the Tokai region to Kyushu, causing heavy rain in various places. On the 26th, heavy rain exceeding 150 mm/24 hours occurred in Kumamoto, Osaka, Wakayama, Gifu, Nagano, and other areas due to the warm and humid air from Typhoon No. 7.

Weather forecast for today, the 6th (Monday): The rainy season front will continue to stagnate near western Japan. Be careful of heavy rain mainly in western Japan.

2026/07/06 05:53

Today, the 6th (Monday), the rainy season front will continue to remain stationary near western Japan. Very warm and humid air flows towards the front, causing rain over a wide area from western to eastern Japan.



In western Japan, due to the influence of active rain clouds near the seasonal rain front, there is a risk of heavy rain with thunder mainly in the morning in Kyushu, Chugoku, and Shikoku. The rain clouds that have developed are moving westward little by little, and there are likely to be places in the Kinki and Kii Peninsula where there will be heavy rain accompanied by thunder from around noon to around evening. The heavy rains have loosened the ground in some places, making it more prone to landslides, so we need to be careful and alert to landslides, and be careful of flooding in low-lying areas, flooding roads, and rising river waters.

Rain clouds will spread from Tohoku to eastern Japan, and the weather will be like the rainy season, where the rain will come and go. Please be careful of thunderstorms in Hokuriku in the afternoon. In Hokkaido, there will be a lot of clouds and there will be some places with showers in the morning.



The daytime temperature will rise to around 30c in western Japan even when it rains, and in many places in eastern Japan it will be around 25c. It looks like it's going to be hot and humid, typical of the rainy season. In northern Japan, temperatures tend to rise in areas with sunny days, and Akita's maximum temperature is expected to be 30 degrees Celsius in midsummer. Please make sure to stay hydrated frequently to avoid heat stroke.

Weather for tomorrow 6th (Monday) The rainy season continues in western and eastern Japan...

2026/07/05 17:33

The rainy season front is stationary from western Japan to eastern Japan, and the rainy season sky is likely to continue.

Rain is expected to fall over a wide area of western and eastern Japan due to the influence of the rainy season front. There is a risk of locally heavy rain in western Japan, especially in the morning. Even if there is little sunlight, it will be hot and humid during the day. Take precautions against heatstroke by using an air conditioner or dehumidifier. In the Kanto region, the weather will be unstable with rain coming and going. Even if it's not raining in the morning, bring an umbrella with you when you go out. Clouds are expected to prevail in northern Japan.
