Expert: Why Japan's bear problem is here to stayーNHK WORLD-JAPAN NEWS

Key Concepts

• Human-Wildlife Conflict: The increasing frequency of negative interactions between humans and bears.
• Habituation: The process by which bears lose their natural fear of humans due to proximity and lack of negative reinforcement.
• Bear Management Personnel: Specialized staff trained to mitigate bear-human conflicts.
• Breeding Season Dynamics: Seasonal behavioral changes in bears that increase the likelihood of human encounters.

1. Current State of Bear-Human Conflicts in Japan

Fiscal year 2025 marked a record-breaking period for bear-related casualties in Japan, resulting in 13 deaths. Recent incidents highlight the severity of the situation:

• Iwate Prefecture: An 85-year-old man was found dead, with evidence suggesting he was dragged through the woods; a bear was located in the immediate vicinity.
• Okutama (Western Tokyo): A body was discovered 100 meters from a hiking trail, with animal prints indicating a large predator was responsible.
• Tourist Vulnerability: The threat extends beyond local residents, as evidenced by a recent attack on a foreign hiker in Okutama.

2. Factors Driving Increased Encounters

Experts identify several biological and environmental drivers for the surge in incidents:

• Breeding Season: During this period, adult males roam extensively in search of mates. This forces younger bears and mothers with cubs to navigate different territories, often leading them into human-populated areas.
• Population Growth: Data indicates a rising bear population in Japan, with sightings in March doubling compared to the previous year.
• Loss of Fear (Habituation): Bears are increasingly born and raised near human settlements. Unlike previous generations, these bears do not perceive humans as a threat, leading to a dangerous lack of wariness.

3. Safety and Coexistence Guidelines

Experts emphasize that bears are wild animals, not creatures to be approached or fed. Key recommendations include:

• Respecting Wildlife: Acknowledging that bears are part of the natural ecosystem and must be allowed to live naturally.
• Adherence to Guidelines: Hikers and locals must strictly follow local safety protocols and maintain a safe distance from any bear sightings.
• Public Awareness: There is a critical need for the government to better educate tourists on the risks and proper conduct when entering bear-inhabited regions.

4. Long-Term Strategic Countermeasures

The expert, Sato, argues that the issue cannot be solved immediately and requires a sustainable, long-term strategy focused on coexistence. The proposed framework includes:

• Professionalization: Establishing stable, specialized roles for bear management personnel to ensure effective, consistent intervention.
• Regional Investment: Investing in local communities to ensure they are well-prepared and resilient against bear incursions.
• Government Roadmap: The Japanese government has approved a plan to triple the number of local bear management personnel to approximately 2,500 by the year 2030.

Synthesis and Conclusion

The rise in bear-human conflicts in Japan is a multifaceted issue driven by population growth, behavioral changes in bears, and increased human encroachment into wildlife habitats. The transition of bears from fearful, wild animals to habituated creatures near towns necessitates a shift in strategy. By moving away from reactive measures toward a long-term, professionalized management system—supported by government investment and public education—Japan aims to foster a landscape where humans and bears can coexist safely.
