Aogashima: The unique Island with a “Volcano within a Volcano”

Aogashima, an extraordinary volcanic island, is home to some of Japan’s most resilient inhabitants, who live atop an active volcano.

A Remote Volcanic Marvel

Located over 350 km south of Tokyo, Aogashima is the most isolated island in the Izu Archipelago. Rising dramatically from the Pacific Ocean, the island is believed to have formed from layers of volcanic deposits, creating rugged cliffs of hardened lava. Its most remarkable feature? A smaller volcanic crater nestled inside the larger main crater—earning it the nickname of a “double volcano.”

Designated as a Class-C active volcano by the Japan Meteorological Agency, Aogashima’s last eruption in the 1780s caused significant devastation, claiming half of its population. The survivors abandoned the island for decades, and it wasn’t until 50 years later that people gradually returned. Today, the island’s population hovers around 200 residents.

Life on a Volcano

The island’s dual volcanic structure, with its inner crater known as Maruyama, makes it resemble something straight out of Jurassic Park. This unique landscape also inspired the setting for the fictional town of Itomori in the popular anime movie Your Name (Kimi no Nawa).

Due to its steep cliffs and isolated location, Aogashima is nearly inaccessible. Visitors must first travel to Hachijojima Island, 60 km away, and take a single daily helicopter ride that accommodates just nine passengers. However, weather conditions like high winds or dense fog often cancel these flights, adding to the island’s mystique.

A Small Yet Self-Sufficient Village

The island hosts Aogashima Village, Japan’s smallest village, which despite its size, has a post office, restaurants, and a school. However, the only school on the island has just 25 students, and once they turn 15, they must leave for high school elsewhere. This exodus contributes to the island’s steadily declining population.

The volcanic activity is both a challenge and a resource for the islanders. Geothermal energy is used for cooking, heating, and even powering the island’s sauna—offering both residents and visitors a chance to relax in mineral-rich waters. Campers can also cook meals over volcanic steam, making for a unique culinary experience.

A Tranquil Escape

While Aogashima lacks traditional tourist attractions, its allure lies in its isolation, natural beauty, and serene environment. Visitors come to disconnect from the chaos of modern life and immerse themselves in the island’s tranquility.

One highlight is sampling Aochu, a local liquor distilled from sweet potatoes and barley, said to have a uniquely earthy flavor unlike any other spirits in Japan.

The scenery on the island is extremely peaceful and poetic.

Aogashima’s rich folk traditions often reflect themes of farewells and departures, mirroring the reality of its residents, many of whom eventually leave the island for mainland Japan. Yet for those who visit, Aogashima is a sanctuary of peace, seclusion, and natural wonder, offering a rare glimpse into life atop an active volcano.
