Human–bear conflict is a significant issue in Japan. Understanding genetic diversity, population structure, and local population size of the Asian black bear is essential for improving ecological knowledge and developing conservation and management measures of this species. We examined sex, mitochondrial (mt) DNA variations, and 12 nuclear microsatellite genotypes from hair-derived DNA collected in the Kiso region, Nagano Prefecture. After verifying microsatellite genotypes, we identified 30 distinct individuals (six males, 18 females) within an approximately 48 km² area. MtDNA analysis revealed that all males shared haplotype E01, while females possessed three haplotypes, including E07, detected in Nagano for the first time but previously reported in Tohoku region and Toyama Prefecture. STRUCTURE analysis did not reveal any genetic cluster in nuclear DNA, but significant spatial genetic structures were identified in both mtDNA and nuclear DNA. No evidence of a recent bottleneck was detected. This study is the first to examine the local genetic structure of the black bear in Nagano. Although no genetic clusters were detected, the estimated effective population size was not large, underscoring the importance of continued genetic monitoring. These findings provide insights into anticipating potential conflict zones and guiding conservation and management measures in the Kiso region.
