Japan’s Ministry of the Environment has launched a nationwide survey of wild bear populations, marking the first coordinated effort to track the animals’ movements across prefectural borders—a long-standing challenge for regional authorities struggling to balance conservation with human safety. The initiative, announced in a statement last week, follows a series of high-profile bear attacks in Hokkaido, Nagano, and Akita prefectures, where officials have struggled to contain growing conflicts between expanding bear habitats and rural communities.
The survey, set to begin in April, will deploy motion-activated cameras, GPS collars, and DNA sampling across 12 prefectures, including Hokkaido, where brown bears (*Ursus arctos*) have increasingly ventured into residential areas. According to the ministry, preliminary data suggests bears are roaming up to 50 kilometers beyond traditional prefectural boundaries, complicating efforts to implement localized mitigation strategies. “Bears don’t respect administrative borders,” said a senior official from the ministry’s Wildlife Management Division, who requested anonymity. “Our goal is to map their actual ranges so we can align policies—whether that’s food storage regulations, habitat protection, or culling—without duplication or gaps.”
The push for a unified approach comes as regional governments have clashed over bear management tactics. In Hokkaido, where brown bears are classified as a natural monument, authorities have resisted culling programs favored in mainland prefectures like Nagano, where aggressive bears have killed three people in the past two years. Last month, Nagano Governor Masayoshi Takagi publicly criticized Hokkaido’s reluctance to share data, calling the lack of coordination “a national security risk for rural areas.” The ministry’s survey aims to bridge this divide by providing a standardized dataset, though it stops short of mandating uniform policies.
Scientists warn that climate change and shrinking forest habitats are driving bears into closer proximity with humans. A 2023 study by Kyoto University, cited by the ministry, found that bear sightings near human settlements in Japan’s mountainous regions have risen by 40% over the past decade. The survey will also assess the effectiveness of existing measures, such as bear-proof trash bins and electric fences, which have shown mixed results. In Akita Prefecture, where black bears (*Ursus thibetanus*) are the primary concern, local officials report that only 60% of households comply with food storage guidelines, undermining broader prevention efforts.
The data collection phase will last 18 months, with results expected by late 2026. The ministry has allocated ¥1.2 billion ($8 million) for the project, funded jointly by central and prefectural governments. However, the survey’s success hinges on cooperation from landowners, who must grant access to private property for camera installations. In Hokkaido, where land disputes are common, some farmers have already expressed skepticism, fearing the survey could justify stricter conservation laws that limit agricultural expansion.
Meanwhile, public opinion remains divided. A poll by the Asahi Shimbun last month found that 58% of respondents in bear-affected regions support increased culling, while environmental groups argue that habitat expansion and better waste management would reduce conflicts long-term. The ministry has not yet outlined how the survey’s findings will translate into policy, leaving the door open for further debate. For now, the focus remains on gathering data—though the political and ecological tensions underlying the issue are unlikely to dissipate.
