Narusawa Ice Cave, Ice cave in Narusawa, Japan
The Narusawa Ice Cave extends 156 meters beneath Mount Fuji, featuring basalt lava formations and natural ice pillars throughout its circular underground path.
The cave formed during Mount Fuji's major eruption in 864 CE, when lava flows created tunnels as molten rock drained away, leaving hollow spaces.
During the Edo period, the cave served as a natural refrigeration facility where ice was stored and preserved for delivery to high-ranking officials.
The cave maintains a constant temperature of 3 degrees Celsius throughout the year, with guided tours available between 9:00 AM and 4:30 PM daily.
At 21 meters below ground level, visitors discover the 'Wood Pool,' a section containing permanent ice formations next to volcanic rock structures.
