Weather in the Kanto region looks like the rainy season ahead. Be careful of heavy rain. Weekly weather in the Kanto region

2026/06/29 22:26

From now on, the front will stay near Honshu, and the Kanto region is likely to experience sluggish weather typical of the rainy season.



Tomorrow, the 30th (Tuesday), the Kanto region will be gently covered by a high pressure system centered over the Sea of Japan. On the other hand, the seasonal rain front that extends south of Japan will move northward, so it is expected to be affected by humid air. There will be periods of sunshine during the day, but clouds will likely spread. There is a possibility of rain in the evening, so it's a good idea to bring a foldable umbrella with you when you go out.



The front is expected to move further north tomorrow, July 1st (Wednesday). Clouds will likely spread over the Kanto region.

The low pressure front is expected to move eastward from the 2nd (Thursday) to the 3rd (Friday). It will rain widely in the Kanto region. Looks like it's time for an umbrella.
There is a possibility that the rain will become stronger locally, resulting in heavy rain. Please check the latest information.

After the 4th (Saturday), the front will remain stationary near Honshu, and the weather will continue to be cloudy.

Please note that the way the rain falls will change depending on the location of the front and the degree of development of the low pressure above the front, so please check the latest weather forecast and prepare for heavy rain disasters.



Even if the clouds tend to spread, the maximum temperature is expected to be higher around the 30th (Tuesday) and July 1st (Wednesday). There are some places where midsummer days are expected to reach 30 degrees Celsius, so please take precautions against heat stroke.
Even on rainy days, the high humidity makes it difficult for sweat to evaporate, making it difficult for your body temperature to drop and putting you at risk of heatstroke. Don't forget to take precautions against heatstroke, such as staying hydrated and taking breaks.

2026/06/29 12:14

The rainy season front is stationary in the south of Honshu.
Warm and humid air is flowing towards the seasonal rain front near Tanegashima and Yakushima, causing extremely unstable atmospheric conditions in Kagoshima Prefecture. As a result, cumulonimbus clouds have developed locally in the Amami region, and currently active rain clouds and thunderstorms have been observed.



Today, into the evening of the 29th, there will be localized very heavy rain accompanied by thunder and heavy rain, resulting in heavy rain.
The expected rainfall per hour on the 29th is high in places,
Kagoshima Prefecture (excluding the Amami region) 40mm
Amami region 60mm

From 12:00 on the 29th The predicted 24-hour precipitation by 12:00 on the 30th is high in some places: Kagoshima Prefecture (excluding Amami region) 120 mm
Amami region 150 mm



A level 4 landslide danger warning has been announced in the Amami region.
Please evacuate everyone from dangerous slopes and cliffs.

Also, please be careful of flooding of low-lying areas, rising river levels, lightning strikes, and strong gusts of wind such as tornadoes.
If there are signs that a cumulonimbus cloud is approaching, please take precautions such as moving inside a building.

Weekly weather: Rainy season front stagnant near Honshu; rainy days continue in western and eastern Japan; rainy season is almost over in Okinawa

2026/06/29 07:09

Looking at the weather map for the next week, it looks like the rainy season front will remain stationary near Honshu for many days. In western and eastern Japan, there will be many cloudy and rainy days, especially on the Pacific coast.

A low pressure system is expected to move over the seasonal rain front from around the 1st to the 3rd. When a low pressure system passes, the seasonal rain front becomes more active, and there is a risk of heavy rain or heavy rain accompanied by thunder. Sufficient attention must be paid to landslides, flooding of low-lying areas, and rising river waters. Even after the low pressure system passes, the rainy season front tends to remain stationary, so cloudy and rainy days are likely to continue from western to eastern Japan.
Even on rainy days, the temperature is expected to reach nearly 30 degrees Celsius in some places, and the humid, humid days typical of the rainy season will continue.

On the other hand, Okinawa is expected to have many sunny days in the future, and the end of the rainy season is expected to be near. However, Okinawa/Amami is expected to experience ``significantly higher temperatures'' than normal from around the 1st, and the Japan Meteorological Agency has released early weather information regarding high temperatures. To avoid heatstroke, please take precautions such as hydrating frequently, supplementing with salt, and taking adequate breaks.

Weather forecast for tomorrow, the 29th (Monday): Watch out for sudden rain and thunderstorms in the afternoon, especially in the inland areas of eastern Japan and Hokkaido, and along the mountains.

2026/06/28 20:38

Tomorrow, the 29th (Monday), the rainy season front will be stationary in the south of Honshu. Rain is likely to fall in Okinawa and Amami, which are close to the rainy season front, and southern Kyushu and the Amami region should be careful of heavy rain accompanied by thunder in the morning.



Western Japan is expected to be covered in high pressure and have many sunny days. In eastern Japan, clouds tend to spread around the Kanto region, and there are likely to be some areas with showers due to the influence of local fronts. In other areas, the weather forecast shows clear skies, but there is a possibility that the weather could change suddenly in the afternoon, especially in the inland areas and mountains of eastern Japan and Hokkaido.



The effects of warm, humid air brought in by typhoons and the seasonal rain front will remain in areas around Honshu, and strong cold air is expected to flow into the skies over northern Japan. As a result, atmospheric conditions become unstable and there is a high probability that thunderclouds will form and develop in the afternoon.
The Koshin region and Hokkaido are prone to sudden rain and thunderstorms, and in the Koshin region, please be careful of heavy rain accompanied by thunder. It is likely that there will be localized rain and thunderstorms in the afternoon, even in parts of the southern Tohoku region, northern Kanto region, and inland and mountainous areas of the Tokai region. Even if it's not raining when you go out, it's a good idea to carry a folding umbrella.

The rainy season front is stagnant. Okinawa region should be careful of heavy rain today, the 28th. Heavy rain is expected in southern Kyushu and Amami regions into tomorrow 29th.

Today, the 28th (Sunday), atmospheric conditions in the Okinawa region have become extremely unstable due to the influence of moist air flowing into the front.

In the Yaeyama region, be careful of flooding of low-lying areas, rising water levels, and flooding of rivers, and be careful of landslides.
In the main island of Okinawa, be careful of landslides, flooding of low-lying areas, and rising river waters.
Even in the Miyakojima region, be careful of landslides and avoid flooding of low-lying areas.

In the Yaeyama region and Okinawa main island region, please be careful of strong gusts such as lightning and tornadoes on the 28th (Sunday). If there are signs that a cumulonimbus cloud is approaching, please take precautions such as moving inside a building.
Also, in the Miyakojima region, you need to be careful about lightning strikes, gusts of wind, and sudden heavy rain under developed cumulonimbus clouds.




Southern Kyushu and Amami regions also need to be careful of lightning, tornadoes, violent gusts, and sudden heavy rain through tomorrow, the 29th (Monday).
The rainy season front is expected to move northward to Tanegashima and Yakushima areas by tomorrow.
