Japan's Bear Crisis Changes Autumn Hiking Plans as Death Toll Reaches Record 12

Record deaths cast a shadow over autumn outings

Twelve people were killed in bear attacks across Japan between April and October 2025, according to the Ministry of the Environment, a record for that period. As of November 4, the crisis was changing how people approached the country's autumn foliage season, with hikers reconsidering destinations and authorities seeking help for communities struggling to respond.

A Japan Meteorological Corp. survey found that 77 percent of hikers felt anxious about encountering bears and 52.8 percent had changed their plans. Conducted between late September and mid October through a hiking information website, the survey received 3,594 responses. Sixty percent of respondents said they went hiking at least once a month, placing regular mountain visitors at the center of its findings.

Japan's autumn trails normally attract families, day trippers and experienced mountaineers to wooded valleys and mountain ridges. This season, concern extended beyond remote forests. Bears appeared near farms, trailheads and towns, while incidents at a supermarket, an airport and a tourist bus stop brought the danger into places associated with everyday life.

The ministry recorded 108 injuries from April through September, a tally described as keeping pace with last year's high. Hokkaido and the Tohoku region of northern Honshu remained the main hotspots, but sightings and close encounters also reached prefectures around Tokyo. For residents and visitors, the immediate decisions were practical: which mountain to choose, whether to travel alone, what equipment to carry and when to turn back.

How the toll climbed through 2025

Japan experienced 219 bear attacks and six deaths in 2023, the highest attack total since national tracking began in 2006. Incidents declined the following year, before rising again in 2025. By the end of July, officials had recorded 55 attacks and three deaths. The autumn increase pushed fatalities to a record level, while injuries passed 100.

The sequence shows how much the situation worsened after summer. The death toll rose from three by the end of July to 12 by the end of October, four times the earlier figure. The April to October total was also twice the six deaths recorded in 2023, although those figures cover different lengths of time.

• 2023: Japan recorded 219 bear attacks and six deaths, with attacks reaching the highest total since tracking began in 2006.
• 2024: Incidents declined before the renewed increase in 2025.
• By the end of July 2025: Officials had logged 55 attacks and three deaths.
• By late August: Tokyo's official bear map had recorded more than 150 reports, mainly in Okutama and Hinohara.
• April through September: The Ministry of the Environment recorded 108 injuries.
• April through October: The ministry recorded 12 deaths, a record for that period.
• Late September to mid October: The hiking survey gathered 3,594 responses as concern affected autumn travel plans.

Iwate and Akita, northern prefectures with extensive mountains and aging rural communities, accounted for a large share of incidents. Both had logged thousands of sightings in recent years. In Hokkaido, reports had already reached triple digits by spring.

Tokyo's sightings were concentrated in its western mountain districts rather than its central urban streets. Okutama and Hinohara were the main locations on the official map, illustrating how bear monitoring had become part of planning an outing even within the capital's administrative boundaries.

Bears interrupt shopping, travel and sport

Yamagata Airport halted operations after a bear crossed a runway. A women's golf tournament paused when another appeared near the first tee. These interruptions placed wildlife encounters in settings far removed from the narrow mountain paths where visitors might expect them.

In the Kanto region north of Tokyo, a bear entered a supermarket and injured two patrons before escaping. In central Japan's heritage village of Shirakawa go, a tourist waiting at a bus stop was attacked and treated for injuries. The incidents added to public anxiety and prompted closures or patrols.

Schools and university campuses also paused classes following sightings on their grounds. Some mountain roads and trails closed temporarily after reports of aggressive behavior. Each disruption required local officials to make decisions about access, warnings and the availability of people trained to respond.

Autumn tourism supports rural inns, restaurants and transport services. The survey's findings show that visitors were changing travel plans, although no financial estimate of the tourism losses was given. Airport and sporting disruptions also spread concern among families and occasional visitors who seldom considered wildlife when arranging a trip.

Local authorities sought to keep popular destinations open through additional patrols, clearer signs and cooperation among rangers, police and volunteers. Some route closures were temporary, with trails reopening after sightings declined and patrols assessed conditions as safe.

Why bears are moving closer to people

Japan's two bear species occupy different areas. The Asiatic black bear is described as occurring across much of Honshu and parts of Shikoku and Kyushu, while the Ussuri brown bear lives only in Hokkaido. Estimates put the black bear population at roughly 44,000 nationwide and Hokkaido's brown bear population at around 12,000, although precise counts are difficult.

Both species use mixed forests where oak, beech and chestnut trees provide autumn food. Bears also seek food in fields and orchards near villages. When forest food becomes scarce, crops and food waste can draw them toward places where people live and work.

Poor harvests of acorns and beechnuts, known as mast failures, are becoming more frequent and widespread. Mast means the nuts and other tree foods on which bears depend during autumn. A poor season leaves animals searching more widely for calories before winter.

Warmer winters associated with climate change can delay hibernation or bring bears out earlier, extending the period when people might encounter them. Hibernation is the winter period when bears greatly reduce their activity. Changes in its timing can keep animals moving through landscapes used by residents and visitors.

Rural depopulation is changing those landscapes too. Satoyama, the traditionally managed woodland between villages and mountains, once helped maintain a buffer between human activity and wildlife habitat. As communities shrink and land becomes overgrown, that separation becomes less distinct.

Unsecured rubbish, compost and crop residue left after harvest offer easy food around settlements. River corridors and greenbelts can also provide routes through towns, bringing bears near schools and shopping streets when forest food is poor or cold weather arrives before hibernation has begun.

A fatal encounter on Mount Rausu

Hokkaido has Japan's only population of the larger brown bear species. Encounters occur in the mountains of Shiretoko and central Hokkaido, as well as on rural edges of cities including Sapporo. A fatal attack on Mount Rausu in the Shiretoko Peninsula became one of the season's most serious incidents.

A hiker aged 26 was dragged from the trail after surprising a bear around a blind corner. Search teams later recovered his body. Authorities temporarily closed the mountain, evacuated dozens of hikers by helicopter and issued a brown bear warning for the area. Trails subsequently reopened with stronger advisories and patrols.

A familiar adult female bear with two cubs had reportedly approached people before the fatal encounter and shown little fear of deterrents. Rangers and hunters removed the animals in the area after confirming their role. The outcome brought together two difficult responsibilities: protecting people and managing wildlife.

Bears that tolerate people at close range can make a sudden meeting on a narrow trail especially dangerous. Cubs add another concern because a mother may react to a person approaching her young. Blind corners and dense vegetation can leave both a hiker and an animal with little warning.

A regular visitor to Shiretoko reflected on the distance people had become accustomed to keeping from wildlife after the attack:

Now I think people, myself included, had become numb to the distance we should keep from wild animals.

Outside Hokkaido, northern Honshu continued to face frequent sightings. In Tokyo's Tama region, mountain villages also experienced periodic encounters. Hikers in Okutama were urged to carry bells, walk in groups and report fresh droppings or claw marks to local offices. Close encounters may receive little public attention, yet a surprise meeting at short range can quickly become dangerous.

Hikers change destinations, company and equipment

Choosing another mountain was the most common response among survey participants who changed their behavior, at 61.6 percent. Canceling or postponing a hike followed at 29.1 percent, while 25.2 percent chose to go with other people. Across the full survey, 52.8 percent said bears had directly affected their plans.

Those choices included avoiding routes with recent sightings, skipping dawn starts and staying closer to stations and visitor centers. Some hikers chose a different route rather than abandoning a trip altogether. Others delayed an outing or asked friends to accompany them.

Equipment and preparation also changed. The survey found that 76.2 percent carried bells or radios, 68.8 percent checked recent sighting reports before entering a mountain area and 57.4 percent said they now carried bear spray. Municipal websites and visitor center notices became part of planning a walk.

Retailers in some prefectures set aside dedicated areas for bells, whistles and spray, while a few shops offered spray rentals for short periods. Hikers increasingly kept spray within immediate reach rather than packed deep inside a bag. Groups also favored daylight starts and avoided dawn and dusk, when bears are more active.

Marked routes, fresh wildlife signs and current notices influenced decisions during the walk itself. Turning back after finding recent bear signs became part of the response. Hikers said these measures helped them feel more in control while reducing the chance of surprising an animal on a quiet trail.

Authorities expand the emergency response

The Ministry of the Environment urged people planning mountain trips to check local government websites and notices at the destination. Where sightings were frequent, it advised changing mountains or taking other precautions. Its guidance included bells or radios, bear spray, recommended routes and avoiding solo trips.

A meeting of senior officials produced a plan to recruit and fund more licensed hunters and wildlife personnel to respond to bears entering towns and farmland. Local governments increased subsidies and training for recruits, while food baited box traps were placed in areas with frequent incidents.

Japan's hunter workforce has declined and grown older, leaving municipalities dependent on volunteers for trapping and emergency calls. Some prefectures eased local gun rules to make bear removal in residential areas simpler. Officials were also considering rules allowing police officers to use rifles against bears posing an immediate threat in those areas.

Akita sought support as injuries accumulated and local responders became exhausted. The Defense Ministry was preparing to send Self Defense Forces personnel to help set traps and transport carcasses. Under current law, the soldiers would not shoot bears. Their assignment was logistical support for local teams.

Japan's defense minister described the fear residents were experiencing during a recent news conference:

Bears have been appearing in supermarkets, and there is a possibility that a bear may be in front of your house when you wake up in the morning. People are living in great fear.

Akita's governor explained the request for military assistance in a social media post and asked residents for patience as broader measures took effect:

The situation is no longer something the prefecture and municipalities can handle alone.

Authorities were also working to standardize reporting and improve coordination among police, wildlife offices and municipalities. Public messages focused on securing rubbish and agricultural food sources, alongside emergency measures to locate and remove animals near people.

Preparing for a mountain visit

Bear encounters remain uncommon for an individual hiker, but preparation centers on avoiding a surprise meeting and being ready to create distance. Local warnings matter because sightings, closures and animal movements can change the conditions on a particular route.

The advice shared by Japanese authorities and field researchers covers planning, food management and what to do when a bear appears:

• Check municipal websites, park offices and visitor centers for recent sightings and closures before leaving.
• Travel with others when possible. Walking and talking together helps signal that people are nearby.
• Make steady noise with conversation, a bell or a small radio, especially where vegetation limits visibility.
• Avoid dawn and dusk, and plan to remain on marked trails during daylight.
• Keep bear spray where it can be reached immediately. Practice removing its safety tab before the trip and consider wind direction if it must be used.
• Seal food, take away rubbish and scraps, and avoid storing food in a tent.
• If a bear appears, do not run. Back away slowly while facing it, avoid staring into its eyes and keep your voice calm.
• If a bear approaches, the advice described includes raising your arms or opening your jacket to appear larger, preparing spray and, if it continues coming, aiming low to create a cloud between you and the animal.
• Never approach a cub. Retreat along the route you came without running, and use a solid barrier to separate yourself from the area when possible.

Responses during physical contact depend on the species and the nature of the attack. The guidance described for Hokkaido's brown bears includes lying face down and protecting vital areas during a mauling, while the guidance for a persistent attack by an Asiatic black bear on Honshu includes fighting back. Whether an animal is defending itself or pursuing a person matters when choosing a response.

Research discussed in connection with injuries in Akita described less serious harm among victims who lay face down and protected their head and neck, with the account referring to brown bear attacks. The outcome was described as dependent on the circumstances. Prevention remains the central message: watch for fresh signs, make your presence known in thick brush and turn back when conditions feel unsafe.

After returning to a trailhead, visitors were encouraged to report encounters and signs to local authorities. Those reports help offices issue timely notices for the next people planning to use the route.

Keeping communities safe while protecting wildlife

Thousands of bears are culled each year, often under permits near farms and towns. Removing an animal can address an immediate danger, while food waste, poor forest harvests and shortages of trained responders continue to require attention.

Bears are a protected wildlife resource with a place in regional culture and ecosystems. They are also powerful animals capable of causing severe injury, especially when they lose their fear of people or learn to associate settlements with food. Conservation and public safety therefore meet at the same village boundaries, orchards and trails.

Longer lasting measures described in the response include maintaining satoyama buffers, securing rubbish and compost, installing electric fences around vulnerable farms and orchards, and restoring trees that produce autumn food. Training wildlife personnel and supporting new licensed hunters would also give municipalities more people to call when incidents increase.

Town edges need coordinated patrols, rapid alerts and practical prevention messages because rivers and green spaces can carry wildlife close to homes and schools. Shared information among local agencies helps residents and visitors adjust their plans as conditions change.

Japan's autumn season brought together a record death toll, changes in hiking behavior and pressure on rural response teams. Keeping access to nature open depended on immediate precautions and work to restore a safer distance between bears and daily life.
