Ainoshima Island

Ainoshima Island, located in the Shibushi Bay off the coast of Fukuoka Prefecture, Japan, has earned its reputation as one of Japan's "cat islands." The island's feline population dramatically increased after 1945, when cats were introduced to control rodents in the local fishing industry. Today, cats outnumber human residents by approximately six to one, with the island's human population standing at roughly 200 people while an estimated 1,200 cats roam freely across the island.

The island serves as a living example of harmonious coexistence between humans, animals, and nature. The cats have become a defining characteristic of Ainoshima, attracting visitors who seek unique wildlife encounters in an authentic fishing village setting. Unlike more commercialized destinations, Ainoshima maintains its traditional character as a working fishing community, offering visitors a glimpse into rural Japanese island life alongside interactions with its friendly cat population.

Visitors can explore the island on foot, as it measures approximately 500 meters in diameter and can be walked around in roughly 30 minutes. The experience centers on observing and photographing the cats in their natural environment, wandering through narrow village lanes, and enjoying coastal views. The island features a small shrine, traditional fishermen's houses, and scenic walking paths. Visitors should bring their own food and water, as the island has no shops, restaurants, or vending machines. Feeding the cats is permitted, though visitors are encouraged to bring appropriate cat food rather than human snacks.

Ferry service to Ainoshima operates from Shingu Port in Fukuoka, with the journey taking approximately 23 minutes. Shingu Port is accessible via train on the JR Kashii Line to Saitozaki Station, followed by a 15-minute walk to the port. Ferries run several times daily, though schedules vary by season and weather conditions. There is no admission fee to visit the island itself. Visitors should plan their trip carefully around ferry schedules to ensure return transportation, and should respect the island's residents by keeping noise levels down and disposing of all trash properly.
