Japan has approximately 10 islands where cats significantly outnumber the human residents. These aren't cat sanctuaries — they're working fishing villages where cats gradually became the dominant animal after being introduced to control mice aboard fishing boats and in warehouses. The cats are semi-wild, friendly, and photogenic.
Tashirojima (Miyagi)
Tashirojima (田代島) in Ishinomaki City has approximately 100 human residents and several hundred cats. The island also has a cat shrine (Neko Jinja) — according to local lore, a fisherman accidentally killed a cat and built the shrine in apology. Dogs are not permitted on the island (officially to protect the cats; cats are believed to bring good fishing fortune). The island has basic accommodation for overnight stays and a handful of restaurants serving fresh seafood. Fishing is still the primary industry; cats lounge around the fishing harbor waiting for scraps. The art collective Studio Kaze built multiple whimsical cat-shaped lodges on the island.
Aoshima (Ehime)
Aoshima (青島) near Ozu city in Ehime prefecture became internationally famous around 2015 when photos of dozens of cats surrounding a mail boat went viral. The island had 15 human residents and approximately 120 cats at peak count. The cats were originally introduced to control mice aboard fishing boats. Aoshima is reachable by a small ferry from Nagahama port; the ferry runs twice daily with limited capacity. No shops or restaurants exist on the island; bring your own food and water.
Other Cat Islands
Ainoshima (Fukuoka): A small island in Shingu Bay with a sizable cat population, accessible by ferry from Shingu Port. Less crowded than the famous two. Muzukijima (Hiroshima): Cats arrived on this Seto Inland Sea island during wartime and have multiplied since. Sanagijima (Kagawa): Cats and a relatively accessible ferry service from Marugame.
Visitor Etiquette
The cats on these islands are not pets — they're semi-wild community animals. Rules common to all cat islands: don't pick up cats (they'll approach on their terms), don't bring unfamiliar cat food without knowing if it's safe for them (many residents have established feeding routines), keep noise low to avoid stressing the animals, don't bring dogs. Photography is of course welcome — these islands exist partly because of their photographic appeal.
