The Fuji Fugaku Wind Cave is surrounded by the abundant greenery of the Aokigahara Jukai forest in Yamanashi Prefecture, Japan. Once you enter the cave, it is pleasantly cool even in summer, with an average temperature of 3℃. Up until the beginning of the Showa era, it was used as a refrigerator to store the eggs of silkworms. The cave has also been designated as a Japanese natural monument.
