The Narusawa ice cave is a tunnel leading down to an area of 0º where icicles and ice are formed. Blocks of ice were offered to the Japanese nobility during the time when freezers did not exist, and were used to cool rooms under their houses. It’s a dangerous cave where ceilings are low and the smooth rock floor is slippery.
