Yururi islet and Moyururi islet are uninhabited islets off Nemuro Peninsula. Yururi islet is 168.88 ha and Moyururi islet is 31ha. Both islets appear to be around 40 m high round islets with cliffs. The cliffs are breeding sites for northern seabirds. The center of Yurui island has high moor vegetation, and marine vegetation and alpine plants are on the edge of the islet because pastured horses prevent an overgrowth of Bamboo grass. On the contrary, Moyururi islet is covered with Sasa veitchii var. because there are no large grass-eating mammals. The islands are closed to the public.
