Aogashima Volcano is a remarkable natural formation, an active double volcano island located approximately 350 kilometers south of Tokyo. It is essentially a large volcanic caldera with a smaller, active volcano rising from its center. This geological marvel, though administratively part of Tokyo, offers a stark contrast to the bustling metropolis, providing a serene and rugged natural environment.
Visitors consistently praise the island's untouched beauty and the unique experience of being on such a geologically active site. The opportunity to hike to the rim of the inner volcano and utilize steam vents for cooking eggs is a frequently highlighted activity. Reviewers also often mention the incredible stargazing opportunities due to the complete absence of light pollution, creating a truly immersive natural experience. The island's quiet and relaxed atmosphere is a significant draw for those seeking an escape from urban environments.
Practical advice for visiting Aogashima centers heavily on its challenging accessibility. Travelers should be prepared for potential cancellations of both ferry and helicopter services from Hachijō-jima due to weather conditions like mist and strong winds. It is advisable to allocate several buffer days for travel to and from the island. Booking accommodations, such as the local 'minshukus,' and transportation well in advance is crucial, as options are extremely limited. Visitors should bring all necessary personal items, as the island has only one general store with basic supplies. A stay of at least 2-3 days is recommended to account for potential travel delays and to fully explore the island's hiking trails and natural features.
Access to Aogashima is exclusively via Hachijō-jima Island. From Hachijō-jima, visitors can take either a ferry or a helicopter. The ferry service is known for frequent cancellations (reportedly 60% chance) due to weather. The helicopter service, while more reliable (approximately 30% cancellation rate), has only 9 seats and is often booked months in advance, as it serves both residents and business travelers. There is no direct public transport from mainland Japan to Aogashima; all journeys must transit through Hachijō-jima. Travelers should confirm schedules and book tickets far in advance.
The primary complaint from visitors revolves around the extreme difficulty and unreliability of transportation to and from the island. To mitigate this, travelers should plan for significant flexibility in their itinerary, including extra days in Hachijō-jima. It is also wise to have contingency plans for accommodation on Hachijō-jima in case of extended cancellations. Patience and a flexible mindset are essential for a successful trip to Aogashima.
