Overnight, evacuation orders spread across Chiba and Yokohama as Typhoon No.25 (Dujuan) moved north maintaining large, strong force, with forecasters warning of the year's heaviest rain and linear rainbands for Kanto-Koshin and Tokai.
By midday the focus shifted to the Izu Islands, where the Meteorological Agency issued a Level 5 landslide special warning for Oshima Town, prompting an emergency press conference and the government to upgrade its liaison office, followed by record short-time downpours near Mikurajima.
Through the afternoon into night the storm made its closest approach to Kanto, bringing flooding of the Koito and Takasaki rivers and emergency safety orders in Kimitsu, Sodegaura, Ichihara, Otaki and Sakura. Landslides in Yokosuka and Chiba left one dead and four missing, with evacuation orders to over 1.9 million, before Oshima's warning was downgraded to Level 4.
