Tomorrow, the 15th (Wednesday), it will rain over a wide area, with rain clouds moving from Kyushu to eastern Japan.

2026/04/14 12:22

Tomorrow, the 15th (Wednesday), the low pressure system will remain in the south of Japan and will form on the front and move east. As a result, rain is expected to fall over a wide area from Kyushu to eastern Japan. A characteristic of this rain is that warm, humid air flows toward the front, making it easy for rain clouds to develop. Particularly on the Pacific side near the front, the rain may become stronger, resulting in locally concentrated rainfall.



It will rain mainly in Kyushu in the morning, and the rain area will spread to the east as time passes. Rain will become serious in Chugoku and Shikoku around noon, and in the Kinki, Tokai, and Kanto regions from evening to night. As humid air flows into the Kanto region from the south, rain clouds are likely to form, especially in coastal areas, and may temporarily intensify at night.

Temperatures are unlikely to rise due to the rain, and it looks like it will be a chilly day in western Japan. On the other hand, in eastern Japan, the humidity is high and you may feel hot and humid even when it rains. In some areas, the rain can be heavy during the time you return home, so it is essential to prepare rain gear when going out.



The weather will start to improve in many areas the day after tomorrow. The weather is expected to continue to change periodically, so please check the latest weather information.

Today, the 14th (Tuesday), northern and eastern Japan will be mostly covered by high pressure. Meanwhile, the front is expected to remain stationary south of Honshu, and a new low pressure system is expected to form near the East China Sea above the front. As a result, the weather will be downhill in western Japan.



There are places in Kyushu where it will rain from the morning, and the rain will gradually spread to the Chugoku and Shikoku regions in the afternoon. It's a good idea to take an umbrella with you when you go out in the morning in case you get home late. Late at night, rain clouds are likely to spread over some parts of the Tokai and Kanto regions.

In the coastal areas of the Kanto region, clouds tend to spread, and there are likely to be places where thick fog forms in the morning. Please be careful of deteriorating outlook. There will be some sunny spells during the day, and it will be as warm as May.

Northern Japan will be covered by a belt-shaped high pressure system and will have sunny skies in many places. In Tohoku, the blooming of cherry blossoms was announced in Aomori yesterday, the 13th (Monday), and the blooming of cherry blossoms was also announced in Matsumae Town in southern Hokkaido on the 13th. The maximum daytime temperature is around 15c in many places, making it ideal for cherry blossom viewing in places where the cherry blossoms are at their peak.

Rainy weather continues in Kyushu due to the influence of the front. Be careful of sudden heavy rain and lightning strikes.

2026/04/13 17:18

In Kyushu, rain has been falling in some parts of Kyushu since yesterday, the 12th (Sunday), due to the influence of a front extending from the East China Sea.

2026/04/13 12:50

Tomorrow, it will be sunny and warm like spring, mainly in Honshu.
The weather is expected to improve in Hokkaido, where it is currently raining due to the influence of a low pressure system.
The weather is expected to continue to be unstable from the Chugoku region to Kyushu due to the stationary front.



There will be some clouds in Tokyo and Nagoya, but the temperature will rise to around 24c, making it as warm as early May.
In northern Japan and the Sea of Japan side, temperatures are expected to be similar to normal.



As of 12:00 today, many areas are still affected by the dry advisory issued, and caution is required as fire-prone conditions continue. Due to the combination of dry air and high pollen levels, we recommend wearing a mask and moisturizing care when going out.

Weekly weather There will be many days affected by fronts and low pressure next week. Ogasawara Islands should be careful of approaching typhoons

2026/04/12 19:22

The weather from the beginning of the week, the 13th (Monday), is expected to be cloudy on some days due to a stationary front to the south of Japan and a low pressure system moving northeast across the Sea of Japan. There is a possibility that a typhoon will approach the Ogasawara Islands around the weekend, so please be careful.



Today, the 12th (Sunday), the area around Honshu is covered with high pressure, and many places are sunny, but it is raining in Kyushu due to the influence of a front extending from the continent.
The front is expected to extend south of Kyushu tomorrow, the 13th (Monday). The weather in Kyushu and Shikoku will be cloudy and rainy.
In Hokkaido, there will be a trough in the atmospheric pressure tomorrow, the 13th (Monday), and there will be some places where it will rain.
