Issued Sept 7, 2026 — Life-threatening; secure your safety now
On September 7, 2026, the Japan Meteorological Agency (JMA) issued a Landslide Disaster Emergency Warning for Niijima Village, Tokyo, in the northern Izu Islands. This corresponds to Warning Level 5, the highest of Japan's five alert levels, and means rainfall has reached a scale residents have never experienced before. In designated landslide hazard areas in particular, it is extremely likely that some form of disaster has already occurred, and lives are in immediate danger. Ordinary Heavy Rain Warnings and Landslide Warning Information tell you that danger is building. An Emergency Warning is different: it is issued for phenomena on the scale of once in several decades and signals a stage at which disaster may already be underway. It is not a cue to begin evacuating — it is the final-stage message to take life-saving action wherever you are right now. JMA states that Level 5 Emergency Warnings may also be issued for other municipalities. Because waiting for an Emergency Warning before evacuating is already too late, JMA urges everyone to follow the evacuation information their municipality has already issued, without delay. If moving to a designated evacuation site would itself be dangerous, secure your safety on the spot — for example, move to a building as far as possible from cliffs and streams. The warning was issued while it was still dark, so check your surroundings carefully before moving.
Japan's disaster alerts have similar-sounding names, and the difference between levels is hard to read — so people less used to Japanese are especially likely to assume it is still a "wait and see" stage. With a Level 5 Emergency Warning, that misunderstanding is directly life-threatening. Note two things first: this is an Emergency Warning, not an ordinary Warning, and Level 5 is the highest of the five levels. Travelers on the islands may find ferries and flights cancelled and be unable to leave. Rather than forcing your way to a port or airport, prioritize securing safety in the building you are in. If you are staying at a hotel or inn, ask the front desk or your host whether evacuation instructions have been issued. Municipal evacuation information is delivered mainly in Japanese via disaster radio and emergency alert mail, but the JMA website has an English version, and the Kikikuru real-time risk map is color-coded, so it can be read regardless of language. If your location is shaded in a dark color on the map, that alone is grounds to take evacuation action.
On Sept 12, 2026 the JMA raised Mt. Tokachidake (Hokkaido) to Eruption Alert Level 3 (do not approach the volcano). Beware large ballistic ejecta within about 3 km of Crater 62-2 — what hikers, travelers and residents should do now.
On September 11, 2026, Japan's Cabinet Office applied the Disaster Victims Livelihood Recovery Support Act to five Chiba cities hit by the August 2026 heavy rain. Households whose homes were destroyed or severely damaged can apply for support payments.
On Sept 9, 2026 Japan's Cabinet Office announced the Disaster Relief Act now applies to Nagoya City, Aichi (from Sept 8) and Yakushima Town, Kagoshima (from Sept 4) after Typhoon No. 24 and frontal heavy rain. Shelters, emergency housing and home repairs are publicly funded — foreign residents and travelers qualify regardless of nationality.
