Ainoshima Island, located off the coast of Shingū Town in Fukuoka Prefecture, is famous for its population of over 230 cats, making it a paradise for cat lovers. Originally introduced to control mice, the cats on Ainoshima have multiplied and now roam freely around the island. Visitors can take a 20-minute ferry ride from Shingū Port to enjoy the company of these friendly felines, but remember not to feed them or disturb their natural habitat. With beautiful views, historical sites, and cat-themed souvenirs, Ainoshima Island offers a unique and charming experience for all animal enthusiasts.
