You’ve probably never really thought about the possibility of there being bears in Japan. But if you’re planning to hike the historic Nakasendo trail or visit a scenic UNESCO village like Shirakawa-go, you may want to be prepared.

What used to be a rare deep woods sighting has shifted into a real-life safety concern that you need to know about before you head out on a hike.

The Reality of Bears in Japan

The days of assuming that bears are only in the remote mountains of Japan are over. Lately, Asiatic black bears have been venturing much closer to populated areas. They’ve even been spotted in the southern regions of Kansai and Chugoku.

With the number of sightings of black bears in Japan, the Ministry of the Environment has officially confirmed that 2025 set a new record. Japan is seeing bears move into areas where they haven’t been spotted in years, making it more important than ever to stay bear aware when exploring Japan’s countryside.

The 2025 Surge

In my years of traveling through the mountains of Gifu and Nagano, I’ve always felt that the wilderness in Japan was safe. Bears were the last thing on my mind. We used to head into the mountains at least twice a year for camping trips and hiking the Kumano Kodo and Nakasendo trails. Staying safe simply meant clipping a small bell to your pack and making a decent amount of noise.

Recent headlines about bear sightings and the 2025 data have me second-guessing my willingness to venture off into the woods. This increase is looking less like a slight uptick and more like a disaster-level surge in bear sightings and attacks.

I put this chart together to help show how the number of brushes with bears in Japan has jumped in just one year:

Fiscal Year	Total Victims	Fatalities	Reported Sightings	What Happened
2024	85	3	10,000	A relatively quiet year.
2025	230	13	36,814	Current record high.

Why the Sudden Change?

There are two reasons for this sudden surge in bear encounters. One is that the population of bears in Japan has tripled from 15,000 in 2012 to 50,000 in 2025.

But you’re not seeing more headlines just because there are more bears. The second reason is the scarcity of forest foods like acorns and beechnuts. This shortage is driving hungry bears into residential areas and popular hiking spots more than ever.

While the northern Tohoku region remains the primary hotspot for bears in Japan, it’s no longer solely a northern Japan problem. This shortage of food is pushing the bears deeper into the central and southern regions in search of food.

Tohoku Region (The North)

Between the months of April and September of 2025, there were 11,630 bear sightings in the region. Tohoku accounted for over 60% of all bear activity in Japan.

Kanto Region (Tokyo & Surrounding)

The Kanto region is home to Tokyo and has had 845 bear sightings from April to September of 2025. While bear sightings were very rare, they weren’t uncommon in the rural areas of Tochigi, Gunma, and Saitama. But the latest numbers show that bears are now venturing into the suburbs to forage, bringing them directly into densely populated residential areas near Tokyo.

2024 Sightings (April-Sept): 400
2025 Sightings (April-Sept): 845

Chubu Region (The Alps)

With deep mountain valleys sitting right next to farming villages and tourist spots, the Chubu region has a high-traffic zone for bear encounters. A lack of natural food is sending the bears into residential backyards, tourist sites, mountain trails, and town centers in search of food. Sightings in this area nearly tripled in 2025.

2024 Sightings (April-Sept): 590
2025 Sightings (April-Sept): 1,419

Kansai Region (Kyoto & Osaka)

The Kansai surge is largely driven by the same factors affecting the rest of Japan’s main island. In Kyoto, sightings have been concentrated in the northern mountains, but a few bears have wandered into the sightseeing spots of Uji and Arashiyama.

2024 Sightings (April-Nov): 600
2025 Sightings (April-Nov): 1,200

Chugoku Region (The Southwest)

The Chugoku region actually managed to dodge the worst of the 2025 surge. This area stayed relatively quiet thanks to a rare bumper crop of acorns that kept the bears fed and happy deep in the mountains. While lower than the north, sightings did slightly increase.

2024 Sightings (April-Oct): 980
2025 Sightings (April-Oct): 1,060

How to Safeguard Yourself

The increase of bears in Japan doesn’t mean you need to cancel your trip. But you may want to consider adjusting your itinerary if your plans include a hike on isolated trails like the Kumano Kodo and the Nakasendo. If you absolutely must, then handle the trails like a pro and follow these three rules:

Carry a Bear Bell & Make Noise: Most bears will avoid you if they hear you coming. Clip a bell to your backpack, and don’t be afraid to talk loudly or even clap when coming up on blind corners.
Have Bear Spray: Carry a canister of pepper-based bear spray and keep it on your belt, not buried in your bag.
Follow Strict Food Management: Don’t hike with exposed food, food wrappers, or fruit. To an urban bear, a small scent is a meal invitation.

Take Aways

The surge of bears in Japan isn’t a blown-out-of-proportion news story. It’s a real shift in the Japanese landscape. The biggest thing to keep in mind is that the old line between the woods and the suburbs has blurred. Whether you’re on a remote hiking trail or in a popular mountain village, stay bear aware.
