Developments: 2. In August 2026, the Japan Coast Guard issued a second-level alert and evacuation advisory for various ports in the Izu Peninsula and Izu Islands, including Shimoda Port, due to an approaching typhoon. Maritime instructions required vessels of 1,000 tons or more to evacuate outside offshore breakwaters. By early September 2026, Typhoon 24 (Klovane) and associated rain fronts triggered widespread emergency warnings. The Japan Meteorological Agency issued a Level 5 landslide special warning—the highest possible level—for the Izu Islands, specifically affecting Oshima, Niijima, and Toshima, warning that lives are in “imminent danger” due to unprecedented rainfall. Niijima recorded 485mm of rain within a 24-hour period. In Tokyo, Level 4 evacuation instructions remained in effect for landslide-prone areas in Kita Ward, affecting approximately 5,200 residents, while authorities warned of potential flooding near the Zenpukuji River in Suginami Ward. Other regions facing high risks include Kanagawa (Fujisawa, Zushi, Hayama, and Miura), Fukushima (Iwaki City and Hirono Town), Chiba (Sanmu City and Kamogawa), and Miyagi (Ishinomaki and Marumori Town). The extreme weather has caused significant logistical and infrastructure disruptions. JR East implemented planned service suspensions on several major lines, including the Shonan-Shinjuku, Keihin-Tohoku, and Tohoku Main Lines. Commercial facilities like Atre Ueno have announced temporary closures or modified hours. Furthermore, logistics companies including Japan Post and Yamato Transport have reported delivery delays and service suspensions due to road restrictions and ferry cancellations. Numerous schools in Tochigi, Tokyo, Yokohama, and Saitama have also announced closures. As of September 6, 2026, the impact has turned fatal; in Fukushima Prefecture, a woman in her 60s died after her vehicle became trapped in a flooded underpass in Iwaki City. The government has established a liaison headquarters to coordinate emergency responses as the rain front continues to move north. ## Claims - A Level 5 special landslide warning was issued for the Izu Islands, including Niijima.
