Japan has a remarkable concentration of small islands where feral and semi-feral cat populations outnumber human residents — sometimes dramatically. These “cat islands” (neko-jima) have attracted significant domestic and international media attention since the 2010s, generating a specific form of animal-experience tourism that draws visitors to islands otherwise unlikely to feature on travel itineraries. Beyond the famous examples, Japan’s broader tradition of treating cats as auspicious presences (the maneki-neko beckoning cat has Edo-period origins) and the cultural normalisation of community cat management create a context unique to Japan.
Aoshima (Ehime Prefecture)
Aoshima island in the Seto Inland Sea is Japan’s most photographed cat island and probably the world’s most famous. The island’s human population has declined to fewer than 20 permanent residents (all elderly), while the cat population numbers approximately 120. There is no accommodation on the island, no restaurants, and no vehicles. Cats meet the ferry as it arrives, congregate around the island’s single inhabited area, and create the closest thing to a landscape entirely organised around feline existence. Ferries run twice daily from Nagahama Port; the journey takes approximately 30 minutes. Day-trip only.
Tashirojima (Miyagi Prefecture)
Tashirojima off the Oshika Peninsula in Miyagi (part of the Sanriku coast affected by the 2011 tsunami) has maintained a cat culture rooted in its fishing history: cats were kept to protect silkworm production from mice, and local belief held that feeding cats brought good fortune in fishing. The island has a Cat Shrine (Neko Jinja) in its centre and approximately 100 cats against a human population of around 60. The island has limited guesthouse accommodation — an unusual opportunity for overnight cat island experience — and two fishing villages connected by walking paths.
Ainoshima (Fukuoka Prefecture)
Ainoshima off the northern Fukuoka coast has one of the highest cat-to-human ratios in Japan — approximately 200 cats against a human population of around 500. Unlike some cat islands where cats are semi-wild, Ainoshima’s cats are comfortable with human contact and actively seek interaction. The island has a small fishing and agriculture community, a traditional streetscape, and ferry service from Shingu Port (approximately 25 minutes). No accommodation on the island; day trips only.
Okishima (Shiga Prefecture)
Okishima in Lake Biwa — Japan’s largest freshwater lake — is the only inhabited island in the lake. Its cat population of approximately 40 against a small human community is modest compared to the Seto Inland Sea islands, but the setting (freshwater lake island, wooden fishing village architecture, mountain backdrop) is distinctively different. Accessible by ferry from Horikiri Port near Omihachiman.
Cat Cafes: Urban Alternative
For visitors without the time or inclination for island travel, Japan’s cat cafe culture provides urban cat interaction experiences. The cat cafe concept originated in Taiwan but was adopted and extensively developed in Japan from the late 2000s. Tokyo’s Yanaka neighbourhood has a traditional affinity with cats rooted in its temple-district history and maintains semi-feral community cat populations alongside several cat-themed shops and cafes. The guide to Japan dog cafes and animal cafes covers the full spectrum of Japan’s animal experience cafe culture.
