    <p>For a species reintroduction to be successful, understanding the minimum viable population number is important. We examined the occurrence of Eurasian otters (<i>Lutra lutra</i>) on isolated islands to assess whether they can survive in small, isolated habitats. Spraints were investigated, and DNA analysis of the cytochrome <i>b</i> region was conducted, to determine if genetic differences existed between the island and mainland otter populations. Moreover, people living on 13 islands were interviewed for a questionnaire survey. Of the 13 islands, otters were confirmed to occur on nine. Three of these islands seemed too far (≥18 km) for otters to reach by swimming across the sea. Huksan Island is most isolated, with a straight distance of 65 km from the mainland, a sea-crossing distance of 31 km. Yeoseo Island is smallest of the islands, an area of 2.5 km<sup>2</sup>. Our results validated that otter populations inhabited some of these islands. The genetic analyses of otter spraints detected four haplotypes. Furthermore, one type was found in feces from a river on the mainland, 60 km away from the coast. Isolated islands must be considered when establishing a plan to protect the otter population.</p>
