The Japan Meteorological Agency issued a Level 4 landslide-disaster danger warning for Asahikawa City, Hokkaido, on June 13, 2026 [1].

This high-level alert indicates a critical risk of landslides that could endanger human lives. Because Level 4 warnings serve as a primary trigger for local governments to issue formal evacuation orders, residents in high-risk zones must act quickly to ensure their safety.

Officials said that the risk of landslides that could endanger lives is increasing and strict vigilance is required [2]. The agency said that this specific warning level is the benchmark for municipalities to issue evacuation instructions [3].

Local authorities are urging people currently located in landslide hazard areas to monitor official communication channels closely. The Japan Meteorological Agency said that residents should check evacuation information provided by their local governments [4].

Asahikawa City is currently monitoring the terrain for signs of instability. The warning remains in effect as the agency tracks weather patterns that contribute to soil saturation and slope failure [1].

“Strict vigilance is required as the risk of landslides that could endanger lives is increasing.”

A Level 4 warning is one of the highest alerts in Japan's disaster management system, signaling that the window for safe evacuation is closing. By designating Asahikawa City as a high-risk zone, the agency is shifting the responsibility to local municipalities to move residents out of harm's way before landslides occur, reflecting a proactive approach to prevent casualties during extreme weather events.
