Fuji Five Lakes Wind Cave

On a relatively warm day in February I took a day trip towards the Fuji Five Lakes area to visit the so-called wind cave. This is an underground lava cave, in which the temperature pretty much stays around zero degrees throughout the whole year and it is therefore used for storage. While the official name of this particular cave is wind cave (fuketsu - 風穴), I would rather call it an ice cave. In any case it was fascinating, not too cold and there were stalagmites and stalactites everywhere, which you can touch or even lick them if you're close enough. I highly recommend it to anyone interested in caves or natural parts of Mount Fuji.
