Cat Island Japan: Visiting Aoshima and Ehime's Feline Islands

9 min read

What Is Aoshima Cat Island

Aoshima (青島) is a tiny fishing island in Ehime Prefecture's section of the Seto Inland Sea (瀬戸内海) where cats outnumber humans by roughly 6 to 1. According to Setouchi Travel, the island is home to approximately 100 cats and fewer than 15 permanent residents — most of them elderly. The island became internationally famous after photos went viral on social media, earning it the nickname Neko no Shima (猫の島, "Cat Island").

Aoshima is not a cat cafe or a themed attraction. It is a real fishing village in a state of natural decline. There are no shops, no restaurants, no vending machines, and no accommodation on the island. Visitors come for the cats and the experience of a remote Seto Inland Sea island, but the infrastructure is minimal. If you are looking for a polished tourist experience, this is not it. If you want to see what a genuine cat island looks like — quiet, slightly overgrown, and full of curious felines — Aoshima delivers.

The cats arrived generations ago, likely kept to control rats on fishing boats and around the port. With the human population declining over decades, the cats stayed and multiplied. A neutering program was implemented in 2018 to control the population, but the island remains one of the most concentrated cat communities in Japan.

Getting to Aoshima From Matsuyama

Train to Iyo-Nagahama Station

Aoshima is accessed from Nagahama Port in Ozu City. From Matsuyama Station, take the JR Yosan Line to Iyo-Nagahama Station (伊予長浜駅). The journey takes approximately 60-80 minutes depending on the service. Iyo-Nagahama is a small station — when you exit, the port is within walking distance.

If you are coming from further afield, Matsuyama is the main gateway to this part of Ehime. From Hiroshima, you can reach Matsuyama by ferry or Shinkansen plus JR connections. From Osaka or Tokyo, flights to Matsuyama Airport are the fastest option, followed by a bus or train into the city.

Ferry From Nagahama Port

The ferry from Nagahama Port to Aoshima takes approximately 30 minutes. According to H.I.S. and multiple visitor reports, the ferry typically operates only 2 round trips per day with very limited passenger capacity. The boat is small — if it fills up, you wait for the next one or miss the trip entirely.

Ferry pricing was not confirmed in official sources at the time of writing — check locally at the port or search for current schedules online before your visit. The schedule can change due to weather, and rough seas in the Seto Inland Sea can cancel sailings.

The critical point: plan your entire day around the ferry schedule. If you miss the return ferry, there is nowhere to stay on the island. Arrive at Nagahama Port well before the departure time, especially on weekends and holidays when visitor numbers increase.

What the Island Is Actually Like

The Cats: What to Expect

When you step off the ferry, cats will likely be waiting at the port. They are accustomed to visitors and many are friendly, approaching for food and attention. The cats roam freely across the island — on paths, around the port area, on walls, under abandoned structures, and in gardens.

The experience is not a petting zoo. These are semi-feral cats living outdoors. Some are friendly and will sit on your lap; others are skittish and prefer distance. The cats are generally healthy, and the 2018 neutering program has helped stabilize the population. You will see cats of all colors and temperaments.

Many visitors on Reddit note that bringing cat food or treats enhances the experience — cats on Aoshima are used to visitors sharing food. Buy cat snacks at the port or bring your own from the mainland, as there is nothing available on the island.

The Village: A Real Community

Aoshima is a functioning, if diminished, fishing village. The remaining residents are mostly elderly, and the island shows signs of depopulation — overgrown paths, abandoned houses, and quiet streets. According to GaijinPot Travel, visitors should respect the community and avoid treating the island as a playground.

The island is small enough to walk around in under an hour. There is a small shrine, a few occupied homes, and the port area. The landscape is typical of small Seto Inland Sea islands — rocky coastline, low vegetation, and views across the water to neighboring islands.

Remember: this is someone's home. The residents who remain are living their daily lives among the cats and the visitors. Keep noise down, stay on paths, and do not enter private property or buildings unless they are clearly open to the public.

Visitor Etiquette and Island Rules

Visiting Aoshima responsibly matters more than on most tourist sites because you are entering a tiny, vulnerable community. Guidelines:

  • Bring all supplies: water, food, sunscreen, and any medication. There are no shops or vending machines on the island
  • Take all trash with you: the island has no public waste disposal for visitors
  • Follow feeding rules: bringing cat food is generally accepted, but check any posted signs at the port for current guidelines. Do not leave food waste on the ground
  • Respect residents: ask before photographing people. The elderly residents are not part of the attraction
  • Stay on paths: do not enter abandoned buildings or private property
  • Watch the clock: keep track of the ferry return time. There is no accommodation and no backup plan if you miss the boat
  • Be quiet: the island is small and sound carries. Keep voices down, especially near homes

This is not a place to rush through. Plan for a 2-3 hour stay between ferries, bring what you need, and leave the island as you found it.

Other Cat Islands in Japan

Aoshima is one of the most famous cat islands, but Japan has several others. Each has a different character:

Island Prefecture Key Features
Aoshima (青島) Ehime Smallest, most concentrated cat population. No facilities. 30-min ferry from Nagahama
Tashirojima (田代島) Miyagi Larger island with cat shrines, manga-themed lodges, and a small shop. More tourist infrastructure
Ainoshima (相島) Fukuoka Accessible island near Fukuoka with cats, walking trails, and some dining options
Manabeshima (真鍋島) Okayama Quiet fishing island in the Seto Inland Sea with cats, fewer tourists

If Aoshima's minimal infrastructure and strict ferry schedule feel too challenging, Tashirojima or Ainoshima offer a more accessible cat island experience with some facilities. For the purest, most remote cat island visit, Aoshima remains the benchmark.

Note that Ehime's Aoshima should not be confused with other places named Aoshima in Japan — there is a more famous Aoshima beach in Miyazaki Prefecture that is an entirely different destination.

When to Visit and What to Bring

Aoshima is accessible year-round, though weather affects the experience:

Season Conditions Notes
Spring (Mar-May) Mild, pleasant Best overall season; comfortable temperatures for walking the island
Summer (Jun-Aug) Hot and humid Bring sun protection; no shade structures on the island. Rainy season (June) may cancel ferries
Autumn (Sep-Nov) Comfortable Good visiting conditions; fewer tourists than spring
Winter (Dec-Feb) Cool to cold Fewer visitors; some cats may be less active. Ferry less likely to cancel due to typhoons

What to bring:

  • Water and snacks (for yourself — there is nothing on the island)
  • Cat food or treats (bought at the port or brought from the mainland)
  • Trash bags (take everything off the island with you)
  • Sun protection in summer
  • Comfortable walking shoes
  • Camera
  • Cash (for the ferry — card payment unlikely at the port)

Allow a full day for the trip from Matsuyama, including the train to Iyo-Nagahama, waiting for the ferry, time on the island, and the return journey. The island itself only requires 2-3 hours, but the logistics fill a day.
