Cat Rock is in the ocean near the southwestern end of Rebun Island, 25 km off Japan’s northernmost city, Wakkanai in Hokkaido. Cat Rock is a 25 m tall rock, which resembles a cat sitting with her back hunched up and viewing the Sea of Japan. With the ears erected and the tail extending straight to the rear, its cute appearance excites a smile of tourists. Is she ignoring us as she feels like it? Or is she fascinated by something in the distance? It gives us various impressions according to our state of mind.
