Announced Sept 30, 2026 — 27 municipalities in Chiba, Tokyo and Kanagawa
On September 30, 2026, Japan's Cabinet Office (Director-General for Disaster Management) released the second report on how the Disaster Relief Act applies to the Typhoon 25 disaster. The legal basis is Article 1(1)(iv) of the Act's Enforcement Order, which covers situations where many people have suffered, or risk suffering, harm to life or body. Coverage now totals 27 municipalities: 15 cities, 8 towns and 1 village in Chiba (Choshi, Kisarazu, Noda, Narita, Asahi, Katsuura, Nagareyama, Kamogawa, Kimitsu, Futtsu, Sodegaura, Minamiboso, Sosa, Katori, Isumi; Sakae, Kozaki, Yokoshibahikari, Mutsuzawa, Chonan, Otaki, Onjuku, Kyonan; Chosei Village), plus Oshima Town in Tokyo and Miura and Yokosuka in Kanagawa. The key change from the first report is the addition of the two Kanagawa cities: they were damaged by Typhoon 25 and the risk of further damage rose with the following Typhoon 26, so the Act was applied with effective dates of September 20 and 21 even though the public notice came on September 30. The report also notes that the 21 cities and 4 towns in Chiba already covered for the heavy rain from August 13, 2026 continue to need relief and are therefore also covered under the Typhoon 25 disaster.
Relief under the Disaster Relief Act is designed for people actually affected on the ground, and the Act has no provision separating people by nationality or residence status. Evacuation shelters, food and drinking water, and emergency home repairs can therefore cover not only registered foreign residents but also people who happened to be in the area for travel or business. The practical obstacle is language: consultations and applications go through municipal counters, mostly in Japanese. Check first whether your city or town has a foreign-resident consultation desk, multilingual guidance or plain-Japanese materials, and bring an interpreter or use a phone interpreting service if needed. This report also covers an island area, Oshima Town in Tokyo, where travelers stranded by cancelled ferries may need shelters. The two Kanagawa cities were added because Typhoon 25 damage was compounded by the risk of wider damage from Typhoon 26 — later reports may add more areas, so keep checking your municipality and the Cabinet Office for updates.
Japan's Cabinet Secretariat and the Fire and Disaster Management Agency will hold a ballistic-missile evacuation drill in Aizubange, Fukushima on Oct 24, 2026, using a simulated J-Alert broadcast — one of 19 drills planned nationwide in FY2026.
Japan is taking public comment on draft ordinances and notices for the new disaster agency (Bosaicho), including hearing procedure rules, from September 14 to 11:59 p.m. on October 13, 2026.
From Sept 29, 2026, Japan's Meteorological Agency lowered heavy-rain warning thresholds to 70% of normal in Narita, Inzai and Sakae (Chiba) after Typhoon No. 25 breached river levees. Warnings now come with less rain.
