Japan's Bears Surge: "Danger Season" Arrives

Japan is entering its "danger season," with October marking a period of intensified bear activity. Last year, this critical month saw a record number of fatalities from bear attacks, with seven deaths occurring in October alone. The number of reported bear sightings in October 2025, the previous fiscal year, also surged, representing over 30% of the annual total.

This year has already seen unusual bear appearances in urban areas from early spring. Cities like Sendai and Utsunomiya have reported sightings, with Kobe experiencing its first ever in June. Through July of this fiscal year, bear sightings were approximately 40% higher than in the same period last year, raising concerns about potential harm during the autumn months.

Local governments are actively implementing preventive measures. Yamagata Prefecture is clearing brush along riverbanks to deter bears from entering urban areas, while Sendai is deploying AI-powered cameras to detect and alert residents about approaching wildlife. These efforts aim to mitigate risks as Japan heads into the peak season for bear encounters.

Despite proactive measures, expert opinions vary. Shota Mochizuki of Fukushima University suggests that an abundant beech nut forecast might lead to fewer bear appearances in urban areas compared to last year. However, he also warns that an increasing number of bears are becoming accustomed to populated areas, necessitating continued caution and the use of deterrents like bear bells.
