Karurusu Ice Bamboo
In the forests near Karurusu Onsen, a small thermal resort in the mountains above Noboribetsu, ice pillars grow upwards from the ground in a rock cave during winter. In Japanese, such ice stalagmites are called Hyōjun, literally 'ice bamboo shoots' – hence the name.You can reach the cave in deep winter on guided snowshoe tours offered in Noboribetsu. Warm clothing and waterproof shoes are essential.
