Miyakejima is one of Japan's Izu Islands, an archipelago known for its active volcanic chain. This island is particularly notable for its unique geological conditions, including regular volcanic eruptions and some of the highest concentrations of poisonous gases, primarily sulfur, leaking from the ground. This phenomenon has led to a distinctive 'gas mask tourism' where visitors are advised, and residents are required, to carry gas masks at all times, creating a truly unusual travel experience.
Visitors consistently highlight the surreal and almost post-apocalyptic atmosphere of the island, which is both its main draw and a point of caution. While the constant presence of gas masks and the potential for sirens can be unsettling, many find the experience profoundly memorable and unlike any other. Reviewers often praise the unexpected natural beauty, particularly the lush landscapes and the exceptional scuba diving opportunities, which reportedly include frequent dolphin sightings. This contrast between the hazardous environment and the vibrant ecosystem is a recurring theme in visitor feedback.
For those considering a visit, it is crucial to be well-prepared. Gas masks are available for purchase at tourist shops upon arrival, which is a practical tip mentioned by those who have visited. Visitors should allocate at least a full day, if not an overnight stay, to fully appreciate the island's unique character and activities like diving. It is advisable to visit during stable weather conditions to minimize risks associated with gas dispersion. This destination is not for the faint of heart or those seeking a typical relaxing vacation; it caters to adventure seekers and those with a strong interest in geology and disaster tourism.
Miyakejima is accessible by boat or helicopter flights from Tokyo. The boat journey offers a scenic route, while helicopters provide a quicker, albeit more expensive, option. It's important to check schedules and any travel advisories in advance, as flights and ferry services can be affected by volcanic activity or gas levels. Public transportation on the island itself is limited, so planning for local transport, such as renting a car or scooter, or arranging tours, is recommended to explore effectively.
The primary complaint revolves around the inherent dangers and the unsettling nature of the environment. The requirement to carry a gas mask and the possibility of emergency sirens can be a significant deterrent for some. To mitigate these concerns, visitors should stay informed about current gas levels and volcanic activity through official channels, adhere strictly to local guidelines, and consider travel insurance that covers such unique risks. Acknowledge that this is an extreme environment and prepare accordingly.
