The heat has eased, and temperatures are typical of this time of year in various parts of the country. There is a large difference in temperature throughout the day in northern Japan.

2026/04/15 06:57

Yesterday, the 14th (Tuesday), the weather was sunny and warm from eastern Japan to the Kinki region, and it was the first summer day in Osaka in two weeks since March 31st. In addition, the temperature in central Tokyo reached 24.6c, which is unseasonably warm and just one step away from summer.



Today, the 15th (Wednesday), will be a day with little sunshine, with cloudy and rainy conditions from eastern to western Japan due to the influence of low pressure and fronts. The heat of the previous day will ease, and temperatures in various places will reach a maximum of around 20 degrees Celsius, which is typical for this time of year. It seems to be a relatively relaxing place.
On the other hand, sunlight is expected to reach northern Japan around mid-morning. During the day, temperatures are expected to reach mid-May temperatures in some places in the Tohoku region, and there will be a large difference in temperature between morning and evening and during the day. Please be careful not to get sick due to the temperature difference.

The predicted maximum temperature is Sapporo 15c, Sendai 17c, Tokyo 21c, Nagoya 19c, Kanazawa 18c, Osaka 19c, Kochi 20c, and Fukuoka 18c.

Today's weather on the 15th (Wednesday): Rain is expanding from the west. Wear rain gear when going out.

2026/04/15 06:33

Today, the 15th (Wednesday), the front is expected to extend from southern China to the east of Japan, and the low pressure above the front is expected to move eastward south of Honshu. As a result, there will be many places in western Japan with rain from the morning, and the weather will also go downhill in eastern Japan.



It will rain widely in western Japan from the morning. The area of rain will move eastward during the day, and it is likely to stop in some parts of Kyushu in the afternoon. Please be careful not to leave your rain gear behind when you return. The sky is likely to rain throughout the day in Chugoku, Shikoku, and Kinki.

The weather seems to be going downhill in eastern Japan. Rain clouds are expected to start forming in the Tokai region from the afternoon, and in the Kanto region from the evening. Don't forget to prepare rain gear even if it's not raining when you go out.

Although there will be some sunshine in the morning in northern Japan, the sky will gradually become cloudy. There are places on the Pacific coast and southern Tohoku where it starts to rain at night, so if you're returning home late, it's a good idea to bring a folding umbrella.

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.

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.
