Aogashima

Aogashima is a small volcanic island about 9km in circumference, floating at the southernmost tip of the Izu Islands, about 360km south of central Tokyo. With a population of just about 170 people, it constitutes Japan's least populated municipality, 'Aogashima Village'. Due to the difficulty of access, it is known as 'the hardest island to reach in Japan' and 'a remote secret island', and in recent years has become a dream destination for travelers seeking mysterious landscapes and unique culture.

The island's greatest feature is its 'double caldera' formation, which is rare even globally. Within the outer rim mountains stands another volcanic cone called Maruyama, with settlements and farmland spreading within, creating a magnificent landscape that evokes the heartbeat of the Earth. From the observation point 'Otonbu', the entire double caldera comes into view, and combined with the expansive blue Pacific Ocean, a breathtaking panorama spreads before you.

At Maruyama in the center of the island, there is a 'Natural Sauna' that utilizes geothermal heat from volcanic activity, allowing visitors to experience a natural sauna using steam that erupts from the ground. Recently gaining attention as a Geopark, volcanic formations such as fumaroles, lava flow traces, and caldera walls can be observed up close. At night, with virtually no light pollution, a starlit sky and the Milky Way appear crystal clear, and it is also known as a prime spot for stargazing.

Access from the mainland requires traveling to Hachijo Island by plane or ship, then proceeding to Aogashima via helicopter (Tokyo Island Shuttle, capacity 9 people) or a ferry boat 'Aogashima-maru'. The ferry has a low operation rate of approximately 50-60%, easily suspended depending on waves, so visits require flexible schedules and mental preparation. There are no traffic lights or convenience stores on the island, and accommodation is limited to just a few guesthouses. While mobile signals are available, complete silence isolated from urban hustle and bustle prevails.

Aogashima's 'Aochu' shochu, made from sweet potatoes grown by island residents using ancient methods with barley koji, is known as an elusive premium spirit and is popular as a souvenir. For travelers seeking unexplored lands, Aogashima is literally 'an island everyone should visit once in their lifetime'. Everyone is surely amazed that such a primitive and mystical place still exists within Japan.
