Visitors can descend into these natural lava tubes, where temperatures remain chilly year-round amidst glistening ice formations and rugged rock walls. Located within the scenic Fuji Five Lakes area, exploring these ancient caverns provides a refreshing and adventurous contrast to gazing at the iconic peak from afar.
