Aogashima

Aogashima is a remote tropical volcanic island located in the Izu archipelago, renowned for its rare double-caldera geography where an inhabited village sits entirely inside the outer crater. The island is surrounded by dramatic ocean cliffs and offers unique geothermal experiences, allowing travelers to cook meals over natural steam vents (hingya) and relax in community geothermal saunas. Visitors typically stay in traditional local minshuku and explore the breathtaking, secluded landscapes.

While commenters admire the mystical, off-the-beaten-path allure of remote Japanese destinations, many express skepticism regarding the logistics. Viewers frequently highlight that traveling to isolated islands is expensive, difficult to organize, and heavily dependent on favorable weather conditions. Others emphasize the need for realistic expectations when visiting less accessible parts of Japan over major tourist hubs.
