About the Cats on Ainoshima

The cats on Ainoshima are extremely used to humans to the point that some might even approach you and rub themselves against you!

Originally, the Ainoshia’s residents introduced cats to the island to protect their fishing gear and crops from mice. Without many natural enemies and being fed well, the number of cats on Ainoshima multiplied.

Tip: It is best not to visit Ainoshima on a hot day because the cats will hide in the shade.

We also want to note that sterilization surgery was performed on the cats on Ainoshima in 2021. The island has been advertised as a cat’s paradise globally. But there are way too many cats on the island than the carers can care for. This has resulted in some cats being malnourished and/or sick. Thus, the hard decision was made by Ainoshima’s residents.

Things to Watch out for on Ainoshima

  • Please don’t feed the cats for their health
  • Don’t try to catch them and bring them somewhere else. They have their territory

It is probably best to only play with the cats that approach you at their own will. For those who want their own space, let’s leave them alone and take photos of them from a distance. This is especially important if you see a cat family. Trying to touch the little kitten will result in an attack from the mother cat.

Important: Although there are restaurants on Ainoshima Island, the main dishes on the set menus are either sashimi or meat dishes. If you are strict with your vegetarian diet, bring your food because the noodle soup broth also contains seafood extract.

Cycling Around Ainoshima Island

Important: The bicycle rental service is currently suspended until further notice.

Ainoshima has a circumference of around 6 km. The best way to enjoy what the island has to offer is probably hiking through the 5.4 km promenade for your chance to meet the wild animals (other than cats) and historical heritage.

As it will take around 2 to 3 hours to stroll through the promenade, how about renting a bicycle to reduce travel time between the small attractions on Ainoshima Island?

The service is available between 10 am and 5 pm (4:30 pm from November to February). The cost is 500 yen for 2 hours for standard bikes and 1,000 yen for 2 hours for electric-assisted bikes.

Close to the ferry terminal, there is a shrine called Wakamiya Shrine. On the precinct, there is a sacred tree called ‘Umino Shiba’ (産の柴). An interesting custom is that the locals use the tree’s leaves as a charm for safe delivery.

Dragon Lord Rock (龍王石)

At the south end of Ainoshima, a Dragon Lord Rock is enshrined. The locals treat the rock as an object of worship for the God of Water named Hachidai Ryūō (八大龍王).

With most islanders working as fishermen, the rock has been revered. A Ryūō Festival is held on the 15th of November to pray for a good fish catch for the following year.

Even if you don’t believe in the myth of a dragon lord, we would still recommend you pay the rock a visit for the magnificent ocean view from where the rock is. Also, while it is hard to tell the size of the rock from a photo, with a height of 216 cm, it is taller than most of us!

Tōmi Guardhouse Ruins (遠見番所跡)

After the Shimabara Rebellion (島原の乱) in 1638, Japan entered an era of national isolation. To monitor the arrival of foreign ships, five guardhouses were established in Fukuoka Prefecture, and one of them is on Ainoshima.

The guardhouse was built on high ground at an elevation of 77 meters. This was so the guards could see as furthest as possible.

Back then, two guards and three foot soilers were stationed at the guardhouse each day. Fukuoka Domain’s ship would be dispatched if a foreign ship was discovered to chase the unwelcome ship away.

Nowadays, you can still see the stonewalls of the guardhouse. Next to it, a white lighthouse replaces the guardhouse.

Taikō Shioi’s Stones (太閤潮井の石)

Although Toyotomi Hideyoshi united Japan, he wasn’t satisfied. So in 1592 and 1597, he sent troops to Korea, hoping to expand the territory of Japan.

On the way to Nagoya Castle (名護屋城) in Saga Prefecture, he stopped by Ainoshima. It is said that Hideyoshi piled thousands of stones and prayed to the Thousand-arms Kannon statue for victory and safe sailing.

At where Hideyoshi made the prayer, a shrine (Iwamiyamiya Shrine, 岩宮神社) was erected.

Ana Kannon (穴観音)

Close to Taikō Shioi’s Stones, there is a cave underneath a cliff that enshrines a Kannon Bodhisattva. The cavern used to be accessible. However, after a recent earthquake, it was determined to be too dangerous to go down the small path, and entry is currently forbidden for your safety.

Ainoshima Stone Tumuli (相島積石塚群)

The tumuli in the southeast of Ainoshima were determined to be the graveyard between the 4th to the 7th century. A total of 254 tombs were discovered during research. Unlike other ancient tombs in Japan that cover the stone chamber with soil, the entire tomb is made of stones on Ainoshima.

Due to its uniqueness, the Tumuli was determined to be a National Historic Site in 2001.

Hanagurise Rock (鼻栗瀬)

Around 300 meters from Ainoshima’s southeast coast, there is a gigantic basalt. The sea cave with a height of 200 meters looks similar to a monocle, which is why the locals called it Megane Rock (めがね岩).
