Recently, Japanese media has highlighted a sharp increase in bear-related incidents. Between April and October this year alone, 176 bear-related accidents resulted in 196 victims—marking the most severe numbers for this period since statistics began in 2006.
For travelers planning to visit Japan—especially those interested in nature, hiking, or rural destinations—understanding the current bear situation and necessary safety measures is extremely important.
Why Are Bears Appearing So Frequently? The Reasons Behind the Increase
In recent years, bear sightings and human–bear conflicts in Japan have increased significantly. This isn’t due to a single cause; instead, it reflects changes in both the natural environment and human society.

- Food shortages in the mountains: Bears traditionally rely on nuts such as acorns, chestnuts, and walnuts. In recent years, climate change and extreme weather have led to poor nut harvests, forcing bears to leave the mountains and search for food in human-populated areas.
- Ecological and demographic changes: Rural depopulation and the shrinking buffer zones between forests, farmland, and residential areas mean that boundaries once separating humans and wildlife are fading. As a result, bears are no longer limited to deep mountains—they now appear near villages, small towns, roads, and even the edges of residential zones.
- The rise of “urban/rural bears”: Some bears have become less fearful of humans and human sounds, venturing into populated or tourist areas. This increases the likelihood of encounters with ordinary travelers.
In other words, you might encounter a bear even if you are not deep in the mountains—especially in areas where nature and residential zones overlap.

What Should Travelers Do? Practical Safety Tips
Below are essential precautions for travelers heading to rural areas, hiking trails, or mountain regions in Japan:
- Check local bear alerts before you go: Many prefectures and towns post updates on their websites, social media, or public notice boards.
- Avoid high-risk times and locations: Bears are more active at dawn, dusk, and night, and near forests or rivers. Stick to daytime, well-traveled, and familiar routes whenever possible.
- Avoid attracting bears: Do not leave food, garbage, fruits, or nuts outdoors. Always secure food properly and take your trash with you.
- Bring bear safety gear: In bear-active regions, consider legal and effective tools such as bear spray. Learn how to use them properly in advance.
- If you encounter a bear, stay calm: Do not run. Slowly back away without turning your back. Avoid shouting or waving aggressively. Prepare your bear spray if you have one.

Essential Pre-Trip Checklist for Independent Travelers

Japan offers more than its bustling cities and convenient transportation. Its forests, mountain trails, and hot spring towns offer a deeper, quieter side of the country. But the recent increase in bear sightings is an important safety concern for anyone exploring rural regions.
We hope this guide helps you prepare well and enjoy your trip safely while creating wonderful memories.
