Bear attacks have increased in Japan, with experts linking the trend to climate shifts and habitat pressures. Here’s what travellers are doing.
Japan’s mountains and forests have always been part of the appeal, but a surge in bear encounters is adding a new layer of caution for travellers.
From April 2025 to March 2026, Japan recorded a historic high of 238 bear attacks and 13 deaths, with incidents concentrated in the Tohoku region and parts of Hokkaido.. With Japan also dealing with more bear sightings, including in areas close to people, the focus is increasingly shifting to how and why encounters are happening more often.. Misryoum reports that Japan is home to Asiatic black bears and larger Ussuri brown bears, both capable of turning up beyond traditional wilderness routes.
The rise matters for travellers because it changes the assumptions behind “safe” itineraries, even if many popular destinations remain unaffected.
Researchers and specialists point to a mix of pressures that can bring bears closer to settlements.. Climate change, habitat loss and Japan’s declining rural population are among the drivers cited for why sightings are increasing, including in urban-adjacent spaces.. Misryoum notes that conditions affecting seasonal food availability can push bears to search for resources for longer stretches of time.
In particular, experts say changes in temperature and weather patterns can disrupt the timing of key foods such as beech nuts and acorns.. When plants lose their usual seasonal rhythms, bears may find fewer nuts and may be forced to adjust their winter plans, including delaying or skipping hibernation and continuing to forage.
This is where the travel risk perception starts to differ: it is not just where bears are, but when they are moving, and what they are hunting for.
Authorities are now trying to reduce the chance of another spike in attacks by issuing warnings across parts of Tohoku as bears come out of hibernation.. Early actions also include deterrents in trouble spots and the use of licensed culling in areas considered worst-affected.. Meanwhile, Japan’s road map for bear management through 2030 includes targets for capture operations.
But experts stress that bear behavior is shaped by more than hunger alone.. Misryoum reports that bears are generally risk-averse and tend to avoid confrontation, with attacks more likely when people unexpectedly stumble on bears that cannot escape or when mothers with cubs are involved.. At the same time, forays into towns can create new patterns, especially if bears successfully find food in human areas.
For tourists, the takeaway is practical rather than alarmist: plans may need to be flexible, and basic preparation can make a difference.
Industry players say the overall risk to travellers is still manageable, with many itineraries centered on major cities and well-frequented destinations.. Travellers interviewed by Misryoum described staying cautious, reading up on what to do during an encounter, and being more selective about where to go, particularly when bear warnings are active.
Experts also emphasize that prevention will likely require both short-term and long-term steps, including habitat restoration and better land management, along with deterrents such as electric fencing where appropriate.. Misryoum notes that community engagement and education are seen as key, alongside a broader mindset shift toward coexistence, where responsibility is shared rather than framed as a problem only on the bear.
