When you search for "Aoshima" in Japan, you'll discover two distinct islands sharing the same name but offering completely different experiences. One island is home to a population where cats outnumber humans 20 to 1, while the other island boasts tropical beaches intertwined with ancient spirituality.

Welcome to Japan's most intriguing case of mistaken identity.

Aoshima, Ehime: Where cats rule the kingdom

Location: Ehime Prefecture, Western Japan

Population: More whiskers than people, with only 4 humans and over 80 cats. It's possibly the only place on Earth where humans are the minority.

Getting there: Take a 30-minute ferry from Nagahama Port near Ōzu City.

In the 1940s, local fishermen introduced cats to the island to manage the rat population. The cats flourished as the human population declined over the years, eventually establishing their feline kingdom on the island.

Today, Aoshima remains in a state of picturesque abandonment. There are no hotels, restaurants, or convenience stores, just aged houses, narrow pathways, and numerous cats that will curiously follow you with gentle purrs.

However, this cat paradise is facing a bittersweet reality. All cats on the island have been spayed or neutered, meaning no new generations will emerge. Biologists predict that within the next decade, this unique ecosystem may disappear entirely, especially as the last human residents age and depart.

Aoshima, Miyazaki: Tropical Serenity Meets Sacred Tradition

Location: Miyazaki Prefecture, Southern Japan

Vibes: Bohemian with a touch of spirituality

Getting there: Just a 20-minute drive from Miyazaki City, or take the JR Nichinan Line to Aoshima Station and walk five minutes to the beach.

Connected to the mainland by a short bridge, this Aoshima is surrounded by the famous "Devil's Washboard," a series of dramatic rock formations that create one of Japan's most impressive coastal landscapes.

At the heart of the island lies Aoshima Shrine, nestled in a subtropical forest that exudes an almost primordial atmosphere. The shrine's vermillion torii gate, especially during sunrise, leaves lasting memories even after you've departed.

The island's microclimate supports over 500 rare plant species, essentially forming a living botanical garden in the middle of the Pacific Ocean.

The nearby Aoshima town has evolved into southern Japan's version of California's surf culture, with consistent waves that make it a paradise for surfers of all levels. Additionally, beach yoga sessions and wellness cafes like Surf Cafe ULU and Cafe Zeal offer vegetarian cuisine and spaces for introspection.

For culinary enthusiasts, local eateries such as Amimoto and Aoshimaya serve some of the freshest kaisendon (seafood rice bowls) and sashimi you can find.

Your choice, your adventure

Choose Cat Island if: You're fascinated by the beautifully peculiar, adore cats, and wish to experience a place that is truly one-of-a-kind while you still can.

Choose Tropical Aoshima if: You're in search of a perfect blend of natural beauty, spiritual calmness, and contemporary beach culture.

Or better yet: Why choose at all? These two extraordinary islands demonstrate that sometimes the most remarkable travel stories begin with a simple case of mistaken identity.

Two Aoshimas, two worlds, infinite possibilities. Which one beckons to you?
