Using geographic information system (GIS), potential habitats in Japan were identified by applying the environmental conditions of otter habitats in Korea. A land use map of Korea was classified into four categories: city, grassland, forest, and water body. Based on the distribution of otter spraints, the optimal habitat conditions for otters were determined. The optimal habitat determined in Korea and Japan was similar to each other. It is unclear if mountain areas would be suitable as they were not surveyed. These findings confirmed that the current environmental conditions of Japan satisfied the conditions for otter survival.
