Japan has at least 15 notable cat islands, but they vary enormously in accessibility, atmosphere, and the type of experience they offer. This comparison helps you choose.
Most Accessible
Ainoshima (Fukuoka) wins for ease of access: 17 minutes by ferry from Shingu Port, which is just 25 minutes from Hakata Station. You can visit on a half-day trip from Fukuoka.
Enoshima (Kanagawa) and Onomichi (Hiroshima) are technically not "islands" in the traditional sense — they're connected to the mainland and have regular cat populations plus full tourist facilities.
Most Remote/Authentic
Tashirojima (Miyagi) and Aoshima (Ehime) offer the most dramatic cat-to-human ratios and feel genuinely remote. Both require ferry rides and advance planning.
Manabeshima (Okayama) is far enough from the tourist trail that you'll likely be one of very few visitors, even on weekends.
Best for Photography
Aoshima: Cats against ocean and abandoned village backdrops. The gathering at the ferry port is iconic.
Tashirojima: The cat shrine in the forest offers atmospheric shots. Natural, less "touristy" feel.
Best for Families
Ainoshima: Short ferry, flat terrain, has vending machines and a small shop. Easy day trip.
Okishima (Shiga): Only 10 minutes by ferry on Lake Biwa. Calm, safe, and family-friendly.
Best Combined with Other Sightseeing
Onomichi: Famous for its temple walk, literature museum, and the Shimanami Kaido cycling route — plus cats.
Enoshima: Combine with the shrine, observation tower, and nearby Kamakura temples.
Our Recommendation
First-time cat island visitor? Ainoshima for easy logistics or Tashirojima for the full experience.
