Typhoon Jangmi made landfall in southern Wakayama Prefecture in western Japan on June 3, 2024 [1, 5].
The storm's arrival triggered widespread flooding and landslide threats across several regions, disrupting critical infrastructure and forcing a massive mobilization of residents to safe zones.
The Japan Meteorological Agency issued flood warnings and evacuation orders for multiple areas as the cyclone moved over the archipelago [1]. According to various reports, the scale of the displacement was significant, with figures ranging from approximately 250,000 residents [8] to as many as 370,000 people [7] forced to evacuate.
In Okinawa, the storm caused injuries to 16 people [4], while other reports said 15 people sustained minor injuries across the affected regions [3]. The storm's impact on the power grid was extensive. Some reports said 60,000 homes lost power [3]. Specific regional data shows that 17,000 households in Okinawa and more than 30,000 households in Kagoshima were affected [6].
The typhoon's path affected a broad stretch of the country, including Okinawa, Kagoshima, and Miyazaki, eventually approaching the Kanto region [1, 2, 4]. The system delivered torrential rain and strong winds that created hazardous conditions for commuters and residents alike [0, 1].
Local authorities continued to monitor the situation as the storm progressed. The combination of heavy precipitation and saturated soil increased the risk of landslides in mountainous terrain, a recurring danger during the Japanese typhoon season.
“Typhoon Jangmi made landfall in southern Wakayama Prefecture”
The landfall of Typhoon Jangmi underscores the vulnerability of Japan's southern and western prefectures to extreme weather. The disparity in evacuation and injury numbers reflects the chaotic nature of real-time disaster reporting, but the overall scale of power outages and displacements highlights the significant economic and social disruption caused by tropical cyclones in the region.
