Tashiro-jima (田代島) is a small island in Ishinomaki City, Miyagi Prefecture, Japan. It lies in the Pacific Ocean off the Oshika Peninsula, to the west of Aji-shima. It is an inhabited island, although the population is quite small (around 100 people, down from around 1000 people in the 1950s). It has become known as “Cat Island” due to the large stray cat population that thrives as a result of the local belief that feeding cats will bring wealth and good fortune. The cat population is now larger than the human population on the island.
