Japan’s natural beauty is legendary—think snow-capped peaks in Hokkaido, ancient forests in Tohoku, and serene hiking trails that draw millions of visitors each year. But in recent months, those idyllic scenes have been overshadowed by a wave of unsettling news: bears venturing into neighborhoods, attacking hikers, and even disrupting airports. If you’re planning a trip to Japan or just keeping up with global wildlife stories, you might be asking yourself, “Why are there so many bear incidents in Japan right now?” It’s a question that’s been echoing across social media and international news outlets, especially as sightings hit record highs in 2025. As someone who’s always fascinated by how humans and nature coexist (or clash), I’ve dug into the latest reports, expert insights, and on-the-ground accounts to break it down.
The Alarming Numbers: A Record-Breaking Year for Bear Encounters
First off, let’s talk stats because they paint a vivid picture. In the fiscal year ending March 2024, Japan recorded a whopping 219 bear attacks—the highest since tracking started in 2006—with six fatalities. That’s a sharp rise from previous years, where incidents hovered around 100 to 150 annually. Fast-forward to 2025, and while attacks have dipped slightly to about 58 by the end of August (with two deaths), sightings have exploded to unprecedented levels. From April to July alone, there were 12,067 reported Asian black bear sightings, the most since records began in 2009. In Hokkaido, sightings topped 100 by April, and urban encounters—like a bear casually strolling across Yamagata Airport’s runway in June—are becoming disturbingly common.
These aren’t just rural problems. Bears have been spotted in downtown areas, golf courses, and even near Tokyo’s suburbs. In August 2025, a fisherman in Okutama got clawed across the face by what seemed like a cub, and a women’s golf tournament in Miyagi was halted mid-game by a wandering bear. Social media is rife with videos and warnings; one X post from April showed a bear roaming a temple in Morioka, while others share graphic survivor stories to raise awareness. For an international audience, this might evoke images of grizzly tales from North America, but Japan’s bears—mainly the Asiatic black bear on Honshu and the larger Ussuri brown bear in Hokkaido—are more elusive by nature. Yet, with encounters up, authorities have declared “bear emergencies” in places like Hokkaido, and even rolled out AI warning systems to detect and deter them.
Food Shortages: Climate Change and Nature’s Unpredictable Cycles
At the core of this surge? Hungry bears. These animals depend on seasonal “mast” crops like acorns, beechnuts, and berries for up to 80% of their diet. But in 2025, experts predict a severe failure in beech nut production across Tohoku’s mountains, much like the disastrous 2023 harvest that triggered the previous spike. Climate change is a big culprit here—warmer temperatures, erratic rainfall, and shorter winters disrupt tree cycles, leading to inconsistent food supplies. Bears, facing starvation, emerge from hibernation earlier, forage longer into the fall, and wander farther from their habitats in search of alternatives like unsecured trash, farm crops, or even pets.
Professor Koji Yamazaki from Tokyo University of Agriculture, a leading bear expert, explains that these aren’t “man-eaters” but desperate opportunists. In years with poor mast, bears raid orchards and villages, sometimes mistaking humans for threats. This fall’s forecast for Tohoku suggests more trouble ahead, with bears potentially delaying hibernation altogether. Interestingly, a good crop in some areas last year led to more cubs surviving, swelling populations and intensifying competition for food this season. It’s a cycle that’s hard to predict, but one that’s exacerbated by global warming—something we all need to address for wildlife worldwide.
Human Factors: Depopulation, Aging Society, and Encroaching Habitats

Japan’s demographic challenges are adding fuel to the fire. The country is aging rapidly, with rural areas depopulating at an alarming rate. Abandoned farmlands and overgrown fields create a “no-man’s land” that bridges bear territories and human settlements, making bold incursions easier. In Hokkaido, the brown bear population has doubled to about 11,700 since 1990, while black bears nationwide are estimated at 44,000—triple the 2012 figure. Fewer people mean less deterrence; gone are the days of bustling farms that kept wildlife at bay.
Compounding this is Japan’s shrinking hunter base. Hunting licenses have halved since 1975, and most hunters are now over 60, struggling to manage the over 9,000 bears culled last year. In July 2025, a hunter went missing in Hokkaido during a spate of attacks, highlighting the risks and shortages. The government has responded by designating bears as “managed wildlife” in early 2025, covering culling costs and easing rifle rules, but it’s a band-aid on a deeper issue. Culturally, Japan reveres nature—bears feature in Ainu folklore as sacred spirits—but balancing conservation with safety is tricky. Recent X discussions reflect this tension, with users debating everything from “urban bears” to calls for better prevention.
Staying Safe: Practical Tips for Hikers and Travelers
If you’re visiting Japan, don’t let this deter you—most areas are bear-free, and attacks remain rare compared to encounters. But in hotspots like Hokkaido’s Shiretoko National Park, Iwate, Akita (which saw 40% of 2023 sightings), or Tokyo’s Tama region, preparation is key. Carry bear spray (legal and available at outdoor shops), bells, or horns to make noise—bears avoid surprises. Travel in groups, stick to trails, and avoid dawn/dusk hikes. If you spot one, back away slowly without eye contact or running; playing dead works for brown bears but fight back against black bears. Check local alerts via apps or the Environment Ministry’s bear map, and secure food waste at home. For cultural sensitivity, remember that in indigenous Ainu communities, bears are respected—learn about this heritage to appreciate Japan’s deep connection to its wildlife.
Frequently Asked Questions (FAQs)
1. Are bear attacks common for tourists in Japan?
No, they’re extremely rare for visitors who stick to popular, patrolled trails. Most incidents involve locals in rural areas. In 2025, out of thousands of sightings, only a fraction led to attacks, and hikers with proper precautions are safe.
2. What should I do if I encounter a bear while hiking in Japan?
Make noise to avoid surprising it, then slowly retreat while facing the bear. Don’t run or climb trees—bears are faster. Use spray if it charges. For black bears, yell and fight back; for brown bears, play dead. Always check regional advisories first.
3. How is climate change contributing to more bear incidents?
Warmer weather causes mast failures, reducing natural food and forcing bears into human areas. Shorter winters mean earlier activity and delayed hibernation, increasing overlap with people. Experts link this to broader global patterns.
4. Has the Japanese government taken steps to address the bear surge?
Yes, in 2025, bears were reclassified for better management, funding culls and easing hunting rules. AI systems, emergency declarations, and public education campaigns are in place. Sightings are monitored via apps to warn communities.
In the end, this bear boom underscores a global truth: As our world changes, so do our interactions with wildlife. Japan’s story is a call to action—protect habitats, adapt to climate shifts, and respect the wild.
