[Weekly Weather] Unsettled weather expected this week due to low-pressure systems and moist air.

2026/10/25 19:57

Today, the 25th, a front extending from a low-pressure system east of Japan remains stationary near the southern coast of Honshu.
Typhoon No. 30 is moving northeast across the East China Sea and is approaching this front.
Warm, moist air from the typhoon is flowing toward the front, resulting in heavy rainfall in some areas across eastern and western Japan.

Typhoon No. 30 is expected to continue moving eastward through tomorrow, the 26th, and is projected to transition into an extratropical cyclone by the morning of the 26th.

A new low-pressure system is forming along the front near the Izu Islands; it is expected to intensify as it moves eastward, passing to the east of Japan, through Tuesday the 27th.



As a result, significant rainfall is expected?particularly across Kyushu and the Pacific-facing regions of western Japan?with some areas likely to experience heavy rain accompanied by thunderstorms.

In eastern Japan, caution is advised through the 27th regarding the potential for lightning strikes, sudden gusts of wind, and localized heavy downpours.

Once the typhoon and low-pressure systems have passed, the weather around Honshu will clear up temporarily on Wednesday and Thursday; however, Hokkaido may see snow due to the influence of a low-pressure system near the Kuril Islands.



Later in the week, the weather is likely to deteriorate once again across the country.
Please stay alert to the changeable weather conditions and keep an eye on the latest weather forecasts.

Weather for tomorrow, Monday the 26th: Rain expected across a wide area from Eastern to Western Japan; be prepared for heavy rain.

2026/10/25 18:00

Tomorrow, Monday the 26th?the start of the new week?is expected to see widespread rain across eastern and western Japan due to the influence of a low-pressure system and a front. Meanwhile, northern Japan will largely be under the influence of a high-pressure system, bringing mostly clear skies.



An extratropical cyclone?formerly a typhoon?is expected to pass over western Japan and move toward the waters south of Honshu. As warm, moist air flows in from the south toward this low-pressure system and front, rain clouds are expected to intensify. In western Japan, in particular, there is a risk of heavy rainfall, with localized downpours potentially reaching 30mm or more?and in some areas, even 50mm or more?per hour. Please remain on alert for landslides, rising river levels, flooding, and the inundation of low-lying areas.

Northern Japan will be under a high-pressure system, with mostly clear weather. In the southern part of the Tohoku region, however, there is a chance of scattered showers by the afternoon, so it would be wise to carry a folding umbrella.

Temperatures in many areas will be lower than they were today (the 25th), and it may feel chilly throughout the day. Please dress warmly when heading out.

2026/10/23 19:44

A summary of the weather and temperatures from October 11 to October 17, 2026.

? Atmospheric Pressure Patterns
On the 11th, a pressure trough extended from west of Kyushu to the East China Sea, where a low-pressure system moved slowly northward. Typhoon No. 28 weakened into a tropical depression east of Japan. Meanwhile, a very strong Typhoon No. 29 moved northward near the Ogasawara Islands. On the 12th, a low-pressure system remained nearly stationary over the East China Sea, while the very strong Typhoon No. 29 moved northward from the vicinity of the Ogasawara Islands toward the area east of Japan. On the 13th, a low-pressure system accompanied by a front moved northeastward across the Sea of ??Japan; Typhoon No. 29 continued its northeastward path, moving from the area east of Japan to a position far to the east. On the 14th, a low-pressure system with an associated front intensified while moving north-northeast across the northern Sea of ??Japan, eventually reaching the vicinity of Sakhalin. Far to the south of Japan, near the Marshall Islands, a tropical depression moved slowly northwestward. On the 15th, a "west-high, east-low" pressure pattern (typical of winter-like conditions) prevailed near Northern Japan. Typhoon No. 30 formed near the Marshall Islands and moved westward while intensifying. On the 16th, the "west-high, east-low" pressure pattern persisted near Northern Japan, and Typhoon No. 30 moved westward near the Chuuk (Truk) Islands. On the 17th, a pressure trough existed over the region from North China to South China, situated behind a high-pressure system. A low-pressure system accompanied by a front moved northeastward through Central China.

? Precipitation
On the 11th, very heavy to heavy rainfall was recorded in areas ranging from the Amami region to the main island of Okinawa. Rain also fell intermittently in Kyushu, primarily along the Pacific coast. On the 12th, rain clouds developed near the Southwestern Islands (Nansei Shoto), with heavy rainfall recorded at three locations in Okinawa Prefecture. On the 13th, a cold front moving across the Sea of ??Japan brought rain to Kyushu starting before midday, with precipitation spreading across a wide area of ??western Japan and the Hokuriku region. On the 14th, the cold front caused rain across a large portion of Honshu, with the affected area expanding throughout the afternoon across eastern and northern Japan. On the 15th, cold air in the upper atmosphere led to scattered rain?at times accompanied by thunderstorms?along the Sea of ??Japan coast in northern Tohoku and across Hokkaido. Additionally, a trough of low pressure brought moderately heavy rain to the Izu Islands. On the 16th, as a low-pressure system passed over northern Japan and a cold front moved southeast across the Sea of ??Japan, a band of rain clouds stretched from the Tohoku region to the southern Sea of ??Japan coast, bringing heavy rain accompanied by thunderstorms. On the 17th, a high-pressure system covered much of Honshu, resulting in virtually no significant precipitation anywhere.

? Temperatures
On the 11th, temperatures reached 30C or higher?classified as a "midsummer day"?in some inland areas of Kyushu and the Chugoku region, with some locations recording temperatures 5?7C above the seasonal average. On the 12th, Honshu was under the influence of a high-pressure system, bringing clear skies and sunshine to many areas. In parts of central Hokkaido, the Chubu region, western Chugoku, and northern Kyushu, temperatures were significantly higher than the seasonal average. On the 13th, southerly winds blowing toward a low-pressure system over the Sea of ??Japan caused temperatures to rise along the Sea of ??Japan coast of Honshu due to the Foehn effect. On the 14th, temperatures rose in areas where warm air flowed in from the south; however, following the passage of the front, cold northerly winds moved in, causing temperatures along the Sea of ??Japan coast to rise only slightly from the afternoon onward. On the 15th, many areas from Kyushu to the southern Tohoku region experienced clear, sunny weather. Temperatures reached 25C or higher?classified as a "summer day"?in several locations, primarily along the Pacific coast of western Japan, including a high of 25.4C in Nagoya, Aichi Prefecture. On the 16th, temperatures reached 26.6C in Tokyo, 26.7C in Nagoya, and 25.8C in Osaka?marking "summer days" (temperatures of 25C or higher) across these locations. On the 17th, temperatures dropped below freezing at about five locations in Hokkaido. During the day, however, areas that received sunshine saw temperatures climb above 25C.



? Weather Summary for the Period (October 11 ? October 17)
Average temperatures across the country were either slightly higher than or above the seasonal norm. Northern Japan, in particular, was frequently covered by warm air, leading to temperatures that were higher than average in many areas. In Hokkaido, locations such as Asahikawa and Kushiro recorded temperatures more than 3C above the seasonal average.
Precipitation was generally below the seasonal norm nationwide, as many areas were under the influence of high-pressure systems; this was especially true along the Pacific coast, where rainfall was significantly lower than average. Conversely, the Southwestern Islands (Nansei Shoto) were more affected by moist air, resulting in rainfall that was slightly above the seasonal average.
Sunshine duration was above the seasonal norm in many areas?particularly across Honshu?due to the frequent presence of high-pressure systems. In the region stretching from the southern part of the Tohoku district to the Kinki district, sunshine duration was more than 1.5 times the seasonal average, with many areas experiencing clear, pleasant autumn weather.
