Toma Limestone Cave
当麻鍾乳洞
A rare limestone cave in Hokkaido, with well-preserved stalagmites, columns and “Dragon Palace”-like chambers. It is designated a Hokkaido natural monument.
Toma Limestone Cave was discovered in 1957 during quarrying. It is about 135 m long and formed in limestone roughly 200 million years old. Its chambers include the Dragon Palace and the Snow Hall, where stalactites, stalagmites and columns stand in dense forests. Because it was discovered late and is strictly managed, it is well preserved and designated a Hokkaido natural monument. The cave stays at about 8°C year-round, so bring a light jacket even in summer. It is open from late April to October, and admission is about ¥500–600. It is located in the mountains of Toma Town, about 40 minutes by car from Asahikawa Station and about 30 minutes from Asahiyama Zoo, so you will need a car.
Opening hours
