Where is it?

Aogashima is a small volcanic island located in the Philippine Sea, approximately 358 kilometers (222 miles) south of Tokyo, Japan. It is part of the Izu Islands, a group of islands administered by the Tokyo Metropolis. Aogashima lies around 60 kilometers (37 miles) south of Hachijojima, another island in the Izu group. Despite its proximity to Tokyo, Aogashima is quite remote, and the only way to reach it is by boat or helicopter.

What is it?

Aogashima is an active volcanic island that is unique for its double caldera, making it one of the most interesting volcanic formations in the world. The island's landscape is defined by dramatic crater walls, lush vegetation, and the dormant Aogashima Volcano, which dominates the island. The island’s steep, rugged terrain and isolated location have contributed to its small population and distinct way of life.

Key features of Aogashima include:

Double Caldera: Aogashima is the only inhabited island in the world with a double caldera. The island's landscape consists of a larger caldera that was formed by a volcanic eruption millions of years ago, and a smaller, more recent caldera within it. The inner caldera is home to the island's only settlement and a small volcanic crater, making it an incredible geological phenomenon.
Aogashima Volcano: The central volcanic feature of the island is Aogashima Volcano, a dormant stratovolcano that formed the island’s current landscape. While it has been quiet in recent times, it remains an active volcano, and the island's inhabitants are mindful of its potential activity.
Scenic Beauty: Aogashima’s steep volcanic slopes are covered in lush subtropical vegetation, including wildflowers, forests, and shrubs. The island’s dramatic cliffs and stunning ocean views make it a paradise for nature lovers and photographers. The island is relatively untouched by modern development, with few roads and buildings, adding to its charm and sense of isolation.
Population: Aogashima is home to a small, tight-knit community of around 200 residents, who mostly engage in agriculture, fishing, and tourism. The island's remote location and difficult terrain have made it challenging to develop large-scale infrastructure, and the residents are known for their self-sufficiency and resilience.
Accessibility: The island is one of the most isolated inhabited places in Japan, and getting there is an adventure in itself. Visitors can reach Aogashima by boat from Hachijojima or by helicopter from Tokyo or Hachijojima. The boat journey can take several hours, and the island’s steep cliffs and unpredictable weather can sometimes make travel challenging. Helicopter flights offer quicker access but are subject to weather conditions.

Best Time to Visit

Spring (March to May): Spring is one of the best times to visit Aogashima, as the weather is mild, and the island’s vegetation is in full bloom. This is an ideal season for hiking, sightseeing, and enjoying the island's natural beauty.
Summer (June to August): Summer brings warmer temperatures, but it can also bring more tourists and less favorable weather for travel due to the increased chances of typhoons. Despite this, the island’s vibrant greenery and outdoor activities make it a popular season for those looking to explore the island’s remote beauty.
Autumn (September to November): Autumn offers pleasant weather and is another great time for outdoor activities like hiking and enjoying the island's landscapes. The fall season also provides stunning views of the volcanic terrain.
Winter (December to February): While winter is the least popular time to visit due to colder temperatures and less predictable weather, it can still be a quiet and peaceful time to experience the island. However, the lack of direct flights and limited boat services may make accessibility more difficult.

Tips for the Trip

Traveling to Aogashima: Getting to Aogashima requires careful planning. Helicopter flights operate from Tokyo or Hachijojima, but these flights are subject to weather conditions and are often limited in availability. Alternatively, visitors can take a boat from Hachijojima, but the journey can take several hours and can be challenging in rough seas. It's essential to check schedules and weather forecasts before planning the trip.
Outdoor Activities: Aogashima offers incredible opportunities for hiking, nature walks, and volcanic exploration. Visitors can hike to the rim of the caldera or visit the volcanic crater at the island’s center. However, because the terrain is steep and rugged, appropriate footwear and preparation are crucial.
Accommodations: Accommodations on Aogashima are limited. There is a small guesthouse and a few inns where visitors can stay, but bookings should be made in advance. Because the island is so small, it is advisable to plan for a short stay to make the most of the experience.
Self-Sufficiency: Due to the island's remoteness, Aogashima is not a place for luxury travel. Visitors should be prepared for a rustic and simple experience, and they may want to bring their own food and supplies, as the local stores are limited.
Respect the Environment: Aogashima is a pristine natural environment, so visitors should be mindful of local regulations and make efforts to preserve the island's unique ecology. Take care not to damage vegetation, leave trash behind, or disrupt local wildlife.
