Japan has more cat cafés than any country on earth — and it also has cat islands: small fishing communities where feline populations far outnumber human residents, the cats having been introduced over generations to control ship-rat populations. Japan’s animal islands extend beyond cats to include tame deer, rabbits, raccoon dogs, and even foxes, making the country’s island geography an unlikely platform for some of the world’s most distinctive wildlife encounters.
Aoshima (Ehime) — The Most Famous Cat Island
Aoshima, in the Seto Inland Sea off Ozu city, Ehime Prefecture, has a human population of fewer than 20 (mostly elderly fishermen) and a feline population of approximately 200. The cats live freely across the entire 1.6 km² island, sleeping in boat hulls, gathering at the harbor for the midday feeding, and greeting the ferry with cheerful indifference. There are no cars, no hotels, no restaurants, and no vending machines. Day trips only; the ferry runs twice daily from Nagahama Port (25 min, ¥240 round trip). The limited ferry capacity means morning departures sell out — arrive at Nagahama Port early.
Tashirojima (Miyagi) — Tohoku’s Cat Island
Tashirojima, off Ishinomaki in Miyagi Prefecture, has around 100 residents and several hundred cats. The island’s fishing history ties cats to luck: fishermen believed cats predicted weather and fish movements, so the feline population was protected and fed. A small Cat Shrine (Neko Jinja) near the center of the island commemorates a cat killed by a falling rock in the 18th century. Manga artist Shotaro Ishinomori (creator of Kamen Rider) designed several cat-themed guesthouses that are the island’s only accommodation. Ferry from Ishinomaki Port (75 min, ¥1,720 one-way).
Okunoshima — Rabbit Island (Hiroshima)
Okunoshima in the Seto Inland Sea was a classified poison gas production facility during World War II. After decommissioning, rabbits introduced to the island multiplied freely. Today approximately 700 semi-tame rabbits roam the island, approaching visitors for food. The Poison Gas Museum provides the island’s sobering historical context alongside the surreal pastoral scene. Camping facilities available. Ferry from Tadanoumi Port (Mihara city, JR Kure Line, 12 min crossing, ¥310). Rabbit food sold at the hotel shop.
Miyajima (Hiroshima) — Sacred Deer Island
The island of Miyajima (Itsukushima), home to the famous floating torii gate, maintains a population of free-roaming deer considered sacred messengers. Unlike Nara’s deer, Miyajima’s deer are wilder and less food-conditioned; they wander the temple precinct and ferry terminal without the aggressive snack-seeking behavior seen in Nara. The deer are protected by the Hiroshima Prefectural Otter Sanctuary status. Ferry from Miyajimaguchi (10 min).
Zao Fox Village (Miyagi)
The Zao Kitsune Mura (Fox Village) near Shiroishi city, Miyagi, houses six fox species in a semi-wild free-roaming environment. Visitors walk through the enclosure alongside over 100 foxes. A small holding area allows supervised handling of young foxes (seasonal, ¥400 extra). Entry ¥1,000. Accessible from Shiroishi-Zao Shinkansen station by taxi (30 min) or infrequent bus.
Practical Tips for Animal Island Visits
Do not feed animals human food — use designated feed sold on-site or at port shops. Wash hands before and after contact. Keep bags zipped — rabbits and deer investigate accessible items. Do not disturb sleeping or nursing animals. Most cat and rabbit islands have no medical facilities; carry basic first-aid items. Return ferries fill up on weekends — confirm the last boat time before exploring.
