Across Japan's coastline, at least 15 islands have earned the designation "cat island" — but ferry frequency ranges from 12 trips per day to just 2, cat populations span from a few dozen to over 120, and some have full tourist facilities while others lack a single vending machine. Choosing the wrong one can mean a wasted day trip.
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 the one the guidebooks skip.
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.
