Mount Fuji's past eruptions and resulting lava flows have created multiple caves in the Fuji Five Lake region around the mountain's northern base. Today, three of these caves have been developed and opened to tourists to be explored without special equipment or guides. Take caution, however, as some of the caves have passages with low ceilings and steep steps that can be slippery when wet.
Retro buses along the Saiko Line operate between Kawaguchiko Station and the caves. For the Bat Cave get off at Saiko-Komoriana (35 minutes) in front of the cave. For the Wind and Ice Caves get off at Fugaku-Fuketsu (50 minutes) from where the Wind Cave can be reached in a few steps and the Ice Cave in a 15 minute walk eastwards along the main road.
Alternatively, the Ice Cave and Wind Cave can be accessed considerably faster by regular buses from Kawaguchiko Station in the direction of Lake Motosuko and Shin-Fuji Station. For the Ice Cave get off at Hyoketsu and for the Wind Cave at Fuketsu bus stops. The one way ride takes about 15 minutes and costs around 650 yen one way. There are departures every one or two hours.
