Japan Bears: Looming Nut Shortage Sparks Attack Fears
9 Dec, 2025
Summary
- A potential 2027 beechnut harvest failure threatens Japanese black bears.
- Poor nut harvests in Tohoku correlate directly with increased bear attacks.
- Rural depopulation and climate change exacerbate bear encounters.
Japan is bracing for a potential rise in bear attacks, with researchers highlighting a projected shortage of beechnuts in 2027. This staple food for Asiatic black bears typically fails in alternating years, and a poor harvest is anticipated following a plentiful 2026.
Poor nut harvests have historically led to an increase in bear encounters. Akita prefecture alone saw 66 injuries and four fatalities this year, a sharp rise from years with abundant crops. Authorities have implemented emergency measures, including revising rules to allow police to shoot bears and deploying the military for trapping operations.
Broader issues like rural depopulation, creating easier pathways for bears into towns, and climate change are also contributing to more frequent encounters. Experts warn that even with better harvests, a significant increase in the bear population means communities remain vulnerable to future attacks.
