As of today, the 9th (Thursday), Typhoon No. 23 is moving north-northwest in the south of Japan.
It is expected to move northwest through the south of Japan and approach the Daitojima region and Okinawa main island region from tomorrow the 10th (Friday) to the 11th (Saturday) the day after.
Then, it will change its course to the northeast and approach the southern Kyushu/Amami region from the 11th (Saturday) to the 12th (Sunday) the next day.
Then, from the 12th (Sunday) to the 14th (Tuesday), it is expected to move eastward across southern Honshu.

Significantly higher temperature than normal; Okinawa records extremely hot days in October (weather summary September 28, 2025 - October 4, 2025)

2025/10/09 11:15

#Summary of the weather for this period (September 28th to October 4th)
The average temperature was easily covered by warm air heading towards low pressure and fronts throughout the period. Even in October, there were many places that recorded midsummer days, and there was a trend towards high temperatures nationwide. In northern Japan, eastern Japan, Kyushu, Okinawa and Amami, there were many places that were more than 2 degrees Celsius higher than normal, and in some places in Hokkaido, the temperature was more than 4 degrees Celsius above normal.

Precipitation was above normal in areas from western Japan to eastern Japan on the Sea of Japan side, which were susceptible to the effects of low pressure and fronts, and in Niigata, Matsue, and Fukuoka, precipitation was more than double normal. On the other hand, Hokkaido, the Pacific coast of eastern and western Japan, Okinawa and Amami, experienced a tendency for less rainfall, and Hokkaido in particular experienced a tendency for considerably less rainfall.

Sunshine hours tended to be higher mainly in northern Japan, Okinawa, and Amami, which were prone to being covered by high pressure. From eastern to western Japan, temperatures were at or below normal in many places, as they were susceptible to the effects of low pressure systems and autumn rain fronts, resulting in more cloudy and rainy days.



#Characteristics of pressure distribution
On the 28th, a low pressure system accompanied by a front moved eastward through the Sea of Japan from near the Korean Peninsula. A front passed through western Japan. On the 29th, a developing low-pressure system passed near Tohoku and headed east of Japan. A front extending from a low pressure system remained in the south of Japan until the 30th. On the 30th, the area around Honshu was widely covered by high pressure. Late in the evening, two low pressure systems formed near the Izu Islands and in the East China Sea. On the 1st, a low pressure system moving over the Izu Islands continued to develop and moved eastward east of Japan, accompanied by a front late at night. The low pressure area near the East China Sea became indistinct by night. A tropical cyclone has formed over the east coast of the Philippines. On the 2nd, a front extending from a low pressure system east of Japan stalled south of Honshu. Typhoon No. 21 occurred off the east coast of the Philippines. On the 3rd, the area around Honshu was widely covered by a mobile anticyclone. A front extending from a low-pressure system in the East China Sea is moving eastward over western Japan. On the 4th, an autumn rain front extended from the East China Sea to the southern coast of Honshu, and a low pressure system above the front moved eastward through the Sea of Japan. In the south of Japan, the low pressure area became a tropical cyclone and gradually approached the Ogasawara Islands.

#Precipitation
On the 28th, due to increased frontal activity, extremely heavy rain was observed in Akune City, Kagoshima Prefecture, which was close to the front, with an hourly rainfall of 52.5mm. On the 29th, rain fell mainly from western Japan to northern Japan on the Sea of Japan side due to the effects of a low pressure system and front. Extremely heavy rain was observed in Mitsui, Wajima City, Ishikawa Prefecture, with an hourly rainfall of 73.5 mm. On the 30th, heavy rain occurred in the Izu Islands near the front. Rain clouds developed locally in Hokuriku, Kinki, and Tokai regions, causing rain. On the 1st, atmospheric conditions became unstable in northern and eastern Japan due to a low pressure trough accompanied by cold air in the upper atmosphere. Torrential rain was recorded in Morino, Shiraoi-cho, Iburi region, Hokkaido, with an hourly rainfall of 124 mm. On the 2nd, atmospheric conditions became unstable in northern and eastern Japan due to the influence of cold air in the sky, and rain and thunderclouds developed. Heavy rain was observed in Matsuhama, Niigata City, Niigata Prefecture, and Imabetsu Town, Aomori Prefecture. On the 3rd, due to the effects of a low pressure system and front moving through the East China Sea, it rained mainly in western Japan, with 73.0 mm of rainfall per hour observed in Izuhara, Nagasaki Prefecture. On the 4th, it rained in western and eastern Japan due to the influence of the autumn rain front, and heavy rain of 84.5 mm per hour was observed in Kurume City, Fukuoka Prefecture.

#Temperature
On the 28th, temperatures rose on the Pacific side due to the influence of warm air heading towards the front. The temperature was observed at 31.0c in Nagoya and 30.6c in Osaka on a midsummer day. On the 29th, temperatures rose in the area south of the front from Kanto to the west. In the Kanto region, temperatures are on the verge of becoming extremely hot, with temperatures rising to 34.5 degrees Celsius in Sano City, Tochigi Prefecture, and 34.4 degrees Celsius in Kumagaya City, Saitama Prefecture. On the 30th, the warm air in the sky receded and the temperature rise slowed down, but the lingering heat was severe in the Okinawa area, with a temperature of 33.4 C observed on Kurume Island. On the 1st, temperatures in northern and eastern Japan were slow to rise due to rain, and the highest temperature in central Tokyo was 23.6 degrees Celsius, marking the first time in 112 days that it was not a summer day. On the other hand, in Okinawa, there were many points that updated the number one value in October. On the 2nd, it was a very hot day of 35.0c on Miyagi Island, Okinawa Prefecture. This is the first extremely hot day of the year in Okinawa, and the first time since records began to record an extremely hot day in October. On the 3rd, it was unseasonably warm in Hokkaido and Okinawa. The temperature was recorded at 28.2c in Sapporo and 34.2c in Naha. On the 4th, the high temperature trend continued in Hokkaido and Okinawa, with Iriomote Island recording a temperature of 34.0c, breaking the record for October.

Weather today, Wednesday, the 8th: Typhoon Northern Expressway: The weather gradually becomes rough in the Izu Islands; Northern Japan is careful of thunderstorms

2025/10/08 06:10

Today, the 8th (Wednesday), a very strong Typhoon No. 22 will head northwards south of Japan. The rain and winds will gradually increase in the Izu Islands and there is a risk of severe damage. Furthermore, Northern Japan needs to be careful of heavy rain and thunderstorms due to the impact of the front passing through.



Due to the influence of the front, rain will fall mainly in the morning, with some places causing heavy rain and thunderstorms. Be careful of lightning strikes, gusts of wind, hail, etc. The winds are strong in Hokkaido, and you need to be careful of strong winds, especially in the coastal areas.


From Kanto to Kinki, it is likely to be affected by typhoons, mainly on the Pacific side. Clouds tend to spread throughout the day and there is a possibility of rainfall, so it's safe to have rain gear when going out.
The rain and winds will gradually increase in the Izu Islands, causing rough weather. Tomorrow, the 9th, there is a fierce wind blowing, which could potentially collapse some of the homes. Take early measures to prevent typhoons.

/Chugoku, Shikoku and Kyushu are likely to have cloud-dominated skyscrapers. Some areas on the Pacific side can reach the sun in the afternoon, but there are likely some areas where showers are found. It's a good idea to carry a folding umbrella when you go out.
The temperature is high and the heat is likely to continue.
