If you have been planning a trip to Aoshima based on viral photos of cats swarming ferry passengers, you need to read this before booking anything. The island you saw in those videos is already gone.
Aoshima, a tiny island in Ehime Prefecture on the coast of Shikoku, became internationally famous around 2013 when tourists discovered its enormous cat-to-human ratio. At its peak, over 200 cats roamed an island with fewer than a dozen human residents. Travel blogs, YouTube videos, and social media posts turned Aoshima into one of Japan's most searched tourist destinations.
But the Aoshima of 2026 is a fundamentally different place. The cat population has dropped to roughly 80 as of December 2024, the human population stands at just 4 permanent residents, and the island has publicly stated that the cats will be gone within the next few years. Anyone visiting with expectations shaped by old photos will be disappointed.
This is not a tragedy in the way Western media often frames it. It is the result of deliberate choices made by local authorities and residents who decided that a managed, humane decline was better than an uncontrolled colony. Understanding that context matters if you are considering a visit.
Why the Cat Population Is Declining
The Spay and Neuter Program
The turning point came in 2018, when authorities launched a large-scale trap-neuter-return (TNR) program on Aoshima. By October 2018, over 210 cats had been sterilized. The goal was never to remove the cats from the island but to prevent further population growth that the island's infrastructure could not support.
With no new kittens being born and natural attrition taking its course, the population has been declining steadily. Most of the remaining cats are elderly. There is no secret or scandal here. This is simply what happens when you sterilize an entire colony and let biology run its course.
The Human Population Crisis
Aoshima's human story is arguably more dramatic than its feline one. The island once supported a fishing community of several hundred people. Like many of Japan's remote islands, depopulation hollowed it out over decades. By the time the cats became famous, the human population was already in single digits.
As of December 2024, only 4 people live on Aoshima year-round. The island has no school, no medical facility, no post office, and no economic activity beyond the ferry service. When the remaining residents can no longer live there, the island will almost certainly become uninhabited. The cats, dependent on human feeding, will not outlast the humans.
Japanese Values of Stewardship
Western visitors sometimes react to Aoshima's decline with alarm, interpreting it as abandonment or cruelty. That reading misses the cultural context entirely.
The decision to sterilize the cats rather than relocate them or let them breed uncontrolled reflects a Japanese approach to animal stewardship that prioritizes humane outcomes over sentimentality. The cats are still fed and cared for by volunteers and the remaining residents. They are living out their natural lives in the only home they have known. The decision was to let the colony end gracefully rather than perpetuate a situation that was becoming unsustainable for both cats and people.
What Aoshima Looks Like Now (2026)
Forget the images of cats flooding the dock. Here is what you will actually find.
The Cats
You will see cats, but far fewer than the famous photos suggest. Expect to encounter 20 to 40 cats during a visit, depending on the weather, the time of day, and the season. The cats tend to cluster around the port area where they are fed, and they are less energetic than younger cats in colony photos from years past. Many are visibly elderly.
The cats are generally friendly toward humans and accustomed to visitors. Some will approach you. Others will ignore you entirely. The frenzied, swarming behavior that made Aoshima famous is largely a thing of the past.
The Island
Aoshima is small. You can walk the entire island in under an hour. There is a single path that loops through the settlement, past abandoned houses, and along the rocky coastline.
There are zero commercial facilities on Aoshima. No restaurants. No cafes. No shops. No vending machines. No public restrooms beyond a basic toilet near the port. No accommodation of any kind. You cannot buy food or water on the island.
This is critically important to understand: Aoshima is not set up for tourists and never was. It is a dying residential island that happens to have cats.
The Atmosphere
Despite everything, or perhaps because of it, Aoshima has a haunting beauty. Overgrown gardens, rusting bicycles, and crumbling stone walls give the island a post-apocalyptic stillness that some visitors find deeply moving. The cats moving silently through the ruins create an atmosphere unlike anything else in Japan.
If you go with realistic expectations and a genuine appreciation for what the island represents, you may find the experience more profound than a simple animal encounter.
How to Visit Aoshima
Getting to Nagahama Port
Aoshima's ferry departs from Nagahama Port in Ozu City, Ehime Prefecture, on the island of Shikoku.
From Tokyo:
| Route | Time | Cost (approx.) | |-------|------|-----------------| | Haneda Airport to Matsuyama Airport (flight) | 1h 40min | ¥15,000-30,000 | | Matsuyama to Iyo-Nagahama (JR Yosan Line) | ~1h 10min | ¥1,280 | | Tokyo to Matsuyama (Shinkansen + limited express) | 4-5h+ via Okayama | ¥18,000-22,000 |
From Matsuyama, take the JR Yosan Line to Iyo-Nagahama Station. The port is a 5-minute walk from the station.
The Ferry
| Detail | Info | |--------|------| | Departures from Nagahama | 8:00 AM, 14:30 | | Return from Aoshima | 8:35 AM, 16:15 | | Journey time | ~35 minutes | | Round trip fare | ¥1,360 | | Capacity | 34 passengers | | Reservations | Not accepted (first come, first served) |
This is the single most important logistical detail: the ferry holds only 34 passengers and does not accept reservations. During peak seasons and weekends, people queue well before departure. If the boat is full, you do not go.
The practical ferry option for most visitors is the morning departure at 8:00 AM, which gives you the full day on the island, with the return at 16:15 PM. The afternoon departure at 14:30 gives you only about 90 minutes on the island before the last return, which is workable but tight.
What to Bring
Because there is nothing available on the island, your packing list is non-negotiable:
- Water: At least 1 liter, more in summer
- Food: Enough for the full day (lunch and snacks)
- Sun protection: Hat, sunscreen, long sleeves in summer
- Rain gear: Weather changes quickly on the Seto Inland Sea
- Comfortable walking shoes: Paths are uneven and occasionally steep
- A bag for your trash: There are no bins on the island. Carry everything out
- Cat treats: Optional, but the cats will appreciate them. Dry treats are best
Do not bring dogs or other animals.
The Visitor Paradox
Here is the uncomfortable truth: Aoshima still receives an estimated 150,000+ visitors annually. For an island with 4 residents, no infrastructure, and a declining cat population, that number is staggering.
The ferry's 34-seat limit acts as a natural throttle, but the sheer volume of people attempting to visit creates its own problems. Litter, disruption to the remaining residents, and stress on elderly cats are ongoing concerns.
The island has posted signs asking visitors to be respectful. The remaining residents have expressed mixed feelings about the tourism that their cats have attracted. They appreciate the attention and the ferry revenue that keeps the service running, but the constant flow of visitors to what is, fundamentally, their home can be intrusive.
Ethical Considerations for Visitors
If you decide to visit Aoshima, keep these principles in mind:
- 1This is not a theme park. Aoshima is a real place where real people live. Treat it the way you would treat a stranger's neighborhood, not a zoo.
- 1Do not chase, pick up, or disturb sleeping cats. Many are elderly and may have health conditions. Let them come to you.
- 1Leave no trace. Bring all your trash back to the mainland. This includes food packaging, bottles, and anything the cats do not eat.
- 1Respect private property. Many buildings on the island are abandoned but still private property. Do not enter them for photos.
- 1Keep noise levels down. With 4 residents, every sound carries. Remember that someone lives within earshot of wherever you are standing.
- 1Consider the timing of your visit. If you are going primarily for Instagram content, ask yourself whether adding to the foot traffic on a dying island is worth it for a few photos.
Should You Still Visit Aoshima?
This is a question only you can answer, and we think the honest answer depends on your motivations.
Yes, if you have a genuine interest in Japanese island culture, depopulation issues, or animal welfare and want to witness a unique moment in time before it ends. Aoshima in its twilight years has a melancholic beauty that rewards thoughtful visitors.
Maybe not, if your primary goal is to be swarmed by cats for photos. That experience no longer exists on Aoshima, and you will likely be disappointed. Cat cafes in Tokyo or Osaka offer more predictable cat interaction if that is what you are looking for.
Definitely not, if you are unwilling to bring your own food and water, cannot handle basic outdoor conditions, or are traveling with young children who need facilities.

Alternatives to Aoshima
If you want a cat island experience with more cats, more facilities, or a less fraught ethical dimension, consider these options:
Tashirojima (Miyagi Prefecture)
Tashirojima has roughly 100 cats and 60-70 human residents. It has a restaurant, guesthouses, the famous Manga Island accommodation, and a beloved cat shrine. The island is larger, more accessible from Tokyo via Sendai, and set up to handle visitors far better than Aoshima. It is the cat island we recommend most often for first-time visitors. Read our full guide to staying overnight on Tashirojima.
Ainoshima (Fukuoka Prefecture)
A short ferry ride from Kitakyushu, Ainoshima is easier to reach from western Japan and has a more relaxed, less touristed atmosphere than either Aoshima or Tashirojima.
Other Cat Islands
Japan has over a dozen islands known for cat populations. For the full list with transport details, cat populations, and difficulty ratings, see our complete cat islands directory.
The Bigger Picture
Aoshima's story is not really about cats. It is about the quiet disappearance of rural Japan, a process that is reshaping hundreds of communities across the country. Over 400 inhabited islands in Japan are projected to become uninhabited within the next few decades. Aoshima is simply the most visible example because its cats made it famous.
Visiting Aoshima with that awareness transforms it from a quirky day trip into something deeper. The empty houses, the elderly cats, the four remaining residents holding on to their home: it is a microcosm of demographic shifts that are redefining what Japan looks like in the 21st century.
If you go, go with respect. And if you decide not to go, that is a perfectly valid choice too.
