Yahagi River เหตุการณ์หมีดำ

Yahagi River opened the recent record with a mother and cub seen in Achi on March 11, 2026, which is the most concerning kind of encounter for hikers because it suggests a family group was moving through the area. Other fresh reports followed in Ena on February 1, 2026, in Nakatsugawa 千旦林 on January 9, 2026, and in Nakatsugawa 茄子川 on January 3, 2026, showing that bears have continued to appear across the river corridor into winter and early spring.

The busiest places in this stretch have been Achi, Ena, Nakatsugawa, and Shimojo, with the heaviest run of reports landing in November 2025 and October 2025, then easing through December 2025, January 2026, and February 2026. Across 309 total black bear sightings here, the pattern points to repeated activity near settled ground and along the valleys rather than a single isolated spot.
