Japanese Prime Minister Sanae Takaichi has urged residents to prepare for the 24th typhoon of 2026, known as Krovanh, and a potentially prolonged period of heavy rain.
In a statement posted on X, Takaichi said the typhoon was expected to approach the Okinawa and Amami regions, urging residents in affected areas to stay vigilant for “sediment disasters, flooding in low-lying areas, and river swelling,” as well as strong winds and high waves.
The Japan Meteorological Agency identified the storm as Typhoon No. 24.
As of Wednesday, September 2, the storm was south of Japan and moving slowly northward.
Forecasts showed it approaching Okinawa and the Amami region around September 3 and 4, although its subsequent path remained uncertain.
Takaichi also warned that the threat could extend well beyond the areas directly affected by the typhoon.
She said a stationary weather front could become more active, producing intermittent rain across a wide area, particularly along the Pacific side of eastern and western Japan.
“In a wide area from eastern Japan to western Japan, precautions and vigilance are necessary against sediment disasters, flooding in low-lying areas, and river swelling,” she said.
The warning follows heavy rain in parts of northern Japan, where a linear band of precipitation produced intense rainfall.
Takaichi said the combination of the typhoon and the weather front could result in substantial cumulative rainfall, with the risk of heavy rain continuing through the weekend.
She also singled out the Hokuriku region, including Ishikawa, Toyama and Fukui prefectures, which experienced heavy rain recently.
“The ground has loosened due to the record-breaking rainfall so far,” she said, warning that “there is a danger of sediment disasters and the like occurring even with relatively small amounts of rain.”
The Japanese government has established an “Information Liaison Room” at the Kantei Crisis Management Centre to gather and coordinate information on the typhoon and heavy rain.
Takaichi urged residents to assess their evacuation plans before conditions deteriorate.
She asked people to use local government hazard maps to determine whether their homes and surrounding areas are safe, identify evacuation centres and routes, and confirm how they would receive emergency information.
The Japanese Prime Minister also urged residents to check emergency supplies and prepare bags containing essential items in case evacuation becomes necessary.
“Please pay close attention to disaster prevention weather information and the latest evacuation information from local governments via radio, television, the internet, and other sources,” she said.
“If you feel even the slightest danger, we earnestly request that you take prompt action without hesitation to protect your own life, acting early and decisively.”
Typhoon No. 24 was reported to have a central pressure of 996 hectopascals and maximum sustained winds of about 18 metres per second on Wednesday.
Its slow movement is a particular concern because it is expected to feed warm, moist air into the autumn rain front, potentially prolonging heavy rainfall over a broad area.
Authorities have therefore warned that significant rainfall may occur even in areas far from the typhoon’s centre, raising concerns about flooding and landslides across a wider part of Japan.
台風第24号が、4日(金)にかけて沖縄地方や奄美地方に接近する見込みです。
台風が接近する沖縄地方や奄美地方では、4日（金）にかけて土砂災害、低い土地の浸水、河川の増水に注意・警戒し、強風や高波に注意して下さい。…
