Iwamatsu Dam เหตุการณ์หมีสีน้ำตาล

Iwamatsu Dam was set against fresh Hokkaido concern on November 25, 2025, when a brown bear weighing about 380 kilograms was trapped and euthanized after experts warned that some bears had not yet fattened for hibernation and may still be searching for food. That is the kind of late season movement that keeps this area on alert.

The activity around Iwamatsu Dam sits within a broader pattern across Hokkaido, with the busiest stretch landing in October 2025 and November 2025 still seeing strong reporting. Across this area, there have been 16 brown bear sightings in total, and the recent reports have come from places such as Shintoku Town, Shikaoi Town, and Kameda Park, showing that the pressure is spread across towns, roads, rail lines, and park edges.
