Two Japanese black bears (Selenarctos thibetanus), an adult male and an adult female with a cub, were radio-tracked in Omote-Nikko, Tochigi Prefecture in summer 1978. The male spent three days in an area of about 26 ha around the trap site of Ide-sawa, and moved to the south slope of Mt. Tanze two kilometers in distance from the trap site. He spent there 10 days in an area of about 38ha. Then his radiocollar dropped out. On the other hand, the female spent three days in an area of about 20ha west of the trap site of Ohsawa, and then disappeared. However, she was sighted with new two cubs on the ton of Mt. Tanze in the next summer.
