Japan has a bear problem, and 2026 is the year it stopped being a rural story
If you are planning an autumn trip to Tohoku, hiking Kamikochi, visiting Nikko, or simply living in a Japanese town with mountains behind it, there is one piece of news you cannot skip this year. In fiscal 2025, bears injured 238 people in Japan and killed 13 — both the highest figures ever recorded. Reported bear sightings jumped from 20,513 to 50,776 in a single year.
Those numbers are not from a remote wilderness. Bears have walked into supermarket car parks, school grounds, hot spring towns and city suburbs. In late 2025 the government took the unusual step of deploying Self-Defense Force personnel to Akita Prefecture to support local authorities.
This guide explains, in plain English, what actually changed, where the risk really is, and the specific behaviour that keeps you safe. It is written for both visitors and foreign residents, because the advice differs more than you would expect.
1｜The numbers, and what they actually mean
| Metric | FY2024 | FY2025 | Change |
|---|---|---|---|
| Reported sightings | 20,513 | 50,776 | About 150% higher |
| People injured | — | 238 | Record high |
| Deaths | — | 13 | Record high |
| Reported attacks | — | 216 | Record high |
Where the sightings were concentrated
| Rank | Prefecture | Sightings (FY2025) | Traveller relevance |
|---|---|---|---|
| 1 | Akita | 13,592 | Nyuto Onsen, Kakunodate, Lake Tazawa |
| 2 | Iwate | 9,739 | Hachimantai, Morioka outskirts, Tono |
| 3 | Miyagi | 3,559 | Naruko Onsen, Zao area |
| 4 | Niigata | 3,528 | Echigo-Yuzawa hiking trails |
| 5 | Aomori | 3,334 | Hakkoda, Oirase Gorge, Towada |
Notice that every one of those is a place tourists genuinely go. Oirase Gorge and Nyuto Onsen are on plenty of “hidden Japan” itineraries. This is why the advice matters even for a two-week trip.
⚠️ Be careful
- Two things the statistics do not show.
- Sightings are reported sightings. More public awareness means more reports, so part of the jump is reporting behaviour — but the casualty and death figures are hard numbers, and those are records too.
- Hokkaido is counted separately in many datasets because it has brown bears (higuma), which are much larger than the Asian black bears (tsukinowaguma) found on Honshu and Shikoku. Hokkaido being absent from a top-5 list does not mean Hokkaido is safe.
2｜Why it happened
Three causes are consistently cited by researchers and by the Ministry of the Environment.
| Food failure in the mountains | Poor crops of acorns, beech nuts and other autumn mast. Bears need to gain weight before hibernation, and when the mountain harvest fails they come down looking for calories. |
|---|---|
| Rural depopulation | Abandoned fields, unharvested persimmon and chestnut trees, and empty houses have created a buffer zone of easy food between forest and town. The old boundary that kept bears up the mountain has thinned out. |
| Fewer hunters, older hunters | The licensed hunter population has declined and aged sharply, reducing both culling capacity and the general wariness bears once had toward humans. |
The consequence is a generation of bears that has learned humans are associated with food and not with danger. Wildlife specialists call these “new generation bears” — animals that never learned to avoid us.
3｜When and where the risk is highest
| Factor | Higher risk | Lower risk |
|---|---|---|
| Season | September to November (pre-hibernation feeding) and April to June (post-hibernation, mothers with cubs) | Deep winter, when most bears are denned |
| Time of day | Dawn and dusk; also night in areas with habituated bears | Midday |
| Weather | Rain, wind, and beside rushing water — the bear cannot hear you coming | Still, dry, open conditions |
| Terrain | Dense brush, stream beds, ridge blind corners, fruit trees, rubbish points | Open, wide, well-used trails |
| Group size | Alone | Three or more people making normal conversation |
The single most useful line in this article is probably this one: a large majority of serious incidents involve a person who was alone and quiet. Walking in a group of three and talking normally is more protective than most gadgets you can buy.
4｜Before you go: a five-minute check
👍 Do this
- Search “[prefecture name] クマ 出没情報” — every prefecture publishes a bear sighting map, usually updated within days. Use your phone browser’s translate function.
- Check the trailhead or park website for closures. Trails do get closed at short notice in bear season and the notice is often Japanese-only.
- Ask at your hotel or ryokan front desk. Local staff know which specific trail had a sighting last week — this is better information than any national dataset.
- If you are staying in a rural area, ask whether the property has a bear bell (kuma-suzu) you can borrow. Many mountain inns keep a box of them.
- Register with your embassy travel notification service if you plan multi-day mountain hiking.
5｜On the trail: what actually works
Preventing an encounter
✅ Key points
- Make continuous noise. Talking, a bell, or a radio. Bears almost always leave if they know you are coming — the danger is surprise at close range.
- Do not use headphones. This is the most common mistake among visitors. You need to hear rustling and you need the bear to hear you.
- Avoid dawn and dusk for trail sections that pass through dense vegetation.
- Be louder near noise cover. Waterfalls, rapids, strong wind — the bear cannot hear you, so raise your voice or increase bell frequency deliberately.
- Never leave food unattended, and do not eat on a blind trail bend. Pack out every wrapper.
- Do not approach a cub. Ever. If you see a cub, the mother is nearby and you are already too close. Back away the way you came.
If a bear is in sight but has not noticed you
Back away quietly the way you came. Do not photograph it. Do not shout to “warn” it. Distance is the entire objective.
If a bear has noticed you
⚠️ Be careful
- Do not run. Bears can run far faster than any human, and running triggers pursuit.
- Do not turn your back. Face the bear and back away slowly.
- Do not scream or make sudden movements. Speak in a low, calm voice so it identifies you as human.
- Do not climb a tree. Asian black bears climb better than you do.
- Do not throw food to distract it. That teaches the bear that people mean food, and endangers the next person on the trail.
- Protect your head and neck if contact becomes unavoidable. Most serious injuries in Japan are to the face and head.
Bear spray: the honest answer
| Does it work? | It is the most effective last-resort deterrent available to a civilian, and it is used widely in Hokkaido and Tohoku. |
|---|---|
| Can I bring my own from home? | No. Pressurised bear spray cannot be carried in checked or cabin baggage on commercial flights. Buy it in Japan. |
| Where do I buy it? | Outdoor shops (Montbell, WILD-1), home centres in Tohoku and Hokkaido, and some mountain lodges. Expect roughly ¥8,000–¥15,000. |
| How do I carry it? | On a hip or chest holster where you can reach it in one second. In your backpack it is useless. |
| Can I take it home? | No — you cannot fly with it. Plan to leave or dispose of it properly before departure. |
6｜If you live in Japan: the around-the-house checklist
Residents face a different problem from tourists. The bear does not come to you on a mountain — it comes to your street, because something there smells like food.
| Attractant | Why it matters | What to do |
|---|---|---|
| Persimmon and chestnut trees | The single most common attractant at Japanese houses in autumn | Harvest early, or have unwanted fruit removed. Do not let it drop and rot |
| Kitchen waste / compost | Bears find it from a long distance | Keep indoors until collection morning. Use a sealed container |
| Pet food and bird feeders | Reliable, high-calorie, repeatable | Bring inside overnight |
| Overgrown lots and riverbanks | Provide a covered corridor right up to houses | Support neighbourhood cutting days — this is one reason the jichikai exists |
| Unused vegetable plots | Sweetcorn and fruit left standing act as a feeding station | Harvest or clear; electric fencing where available |
If a bear is sighted in your area, the local government will usually send a notice through the bousai musen (disaster loudspeakers) and the municipal app or LINE account. Those broadcasts are in Japanese only in most towns, so it is worth asking a neighbour or your city hall’s foreign-resident desk how to receive the alerts.
👍 Do this
- Register for your city’s bousai mail or LINE account — bear alerts go out on the same channel as flood and earthquake alerts.
- Learn two kanji: クマ出没 (bear sighted). If you see this on a sign or a notice board, take it literally and change your route.
- If you have children, check whether the school has changed its walking route. Many Tohoku schools switched to bus or group escorts in 2025.
- Call 110 if a bear is in a residential area. Do not attempt to chase it away yourself.
7｜Should you cancel your trip?
No — and it is worth saying that clearly, because coverage abroad has been alarming.
Japan receives tens of millions of visitors a year. Thirteen deaths in a year is a record and a genuine crisis for rural communities, but the risk to a traveller who stays on major trails, walks in a group and makes noise is very low. Tokyo, Kyoto, Osaka, Hiroshima, Okinawa and almost all standard sightseeing are unaffected.
| Trip type | Realistic risk level | What to change |
|---|---|---|
| City sightseeing (Tokyo, Kyoto, Osaka) | Negligible | Nothing |
| Hot spring towns in Tohoku | Low | Do not walk unlit paths at night; ask the ryokan |
| Day hikes in national parks | Low to moderate | Bell, group, daylight hours, check closures |
| Solo mountain hiking in Tohoku, autumn | Highest | Reconsider going solo; carry spray; tell someone your route |
| Rural cycling / camping | Moderate | Rigorous food storage, never keep food in the tent |
8｜Gear that is genuinely worth having
You do not need much. In order of usefulness for a visitor:
Bear bell (kuma-suzu)
The classic Japanese solution: a small brass bell clipped to your pack. Cheap, light, and it works because it is continuous. Get one with a silencer magnet so you can mute it in towns and on trains, where the constant ringing is considered rude.
Loud whistle
Useful both as a deterrent at distance and as a rescue signal if you are injured. Weighs nothing.
Headlamp
Not a bear tool as such, but being caught out after dark is what turns a low-risk hike into a high-risk one. A headlamp keeps your hands free and lets you keep moving.
9｜Useful Japanese for bear season
| Japanese | Reading | Meaning |

| クマ出没注意 | kuma shutsubotsu chuui | Caution: bear sighted |
| 入山禁止 | nyuuzan kinshi | Entry to the mountain prohibited |
| 通行止め | tsuukoudome | Road / trail closed |
| 熊鈴 | kuma-suzu | Bear bell |
| 熊撃退スプレー | kuma gekitai spray | Bear spray |
| クマが出ました | kuma ga demashita | A bear has appeared |
| ツキノワグマ | tsukinowaguma | Asian black bear (Honshu, Shikoku) |
| ヒグマ | higuma | Brown bear (Hokkaido) |
Frequently asked questions
Is it safe to travel to Japan in 2026 because of the bears?
Yes. The risk is concentrated in rural northern Honshu and Hokkaido, mainly in autumn and at dawn and dusk. Standard city and cultural sightseeing is unaffected. Travellers doing rural hiking should follow the precautions in this guide.
How many people were killed by bears in Japan?
In fiscal 2025, 13 people were killed and 238 injured — both record highs. Reported sightings rose from 20,513 in FY2024 to 50,776 in FY2025.
Which prefecture has the most bear sightings?
Akita, with 13,592 reported sightings in fiscal 2025, followed by Iwate (9,739), Miyagi (3,559), Niigata (3,528) and Aomori (3,334).
Can I bring bear spray to Japan on a plane?
No. Bear spray is a pressurised aerosol and cannot be carried in cabin or checked baggage on commercial flights. Buy it after you arrive, at an outdoor retailer or home centre.
What should I do if I see a bear?
Do not run and do not turn your back. Face the bear, speak calmly in a low voice, and back away slowly the way you came. Do not climb a tree, do not throw food, and do not approach a cub under any circumstances.
Do bear bells actually work?
They work by preventing surprise encounters, which cause most serious injuries. They are not a guarantee, and they are less effective near loud water or in strong wind — in those places raise your voice deliberately.
Are bears a problem in Tokyo or Kyoto?
Not in the central areas visitors use. There have been sightings in mountainous outer parts of some prefectures, but ordinary city sightseeing carries no meaningful bear risk.
Why are there suddenly so many bears?
Three factors are cited: poor autumn crops of acorns and beech nuts, rural depopulation leaving unharvested fruit trees and overgrown land between forest and town, and a declining, ageing hunter population.
Summary
- FY2025 set records: 50,776 sightings, 216 attacks, 238 injured, 13 killed
- Risk concentrates in Akita, Iwate, Miyagi, Niigata and Aomori, plus Hokkaido separately for brown bears
- The dangerous combination is autumn + dawn or dusk + alone + quiet + near food
- Make noise, walk in a group of three or more, and never wear headphones on a trail
- If you meet one: do not run, do not turn your back, back away slowly while speaking calmly
- Buy bear spray in Japan — it cannot be flown in — and carry it on your hip, not in your pack
- Residents: the fight is won at the persimmon tree and the rubbish bin, not on the mountain
- Do not cancel your trip. Change your route planning instead
