History

13-JAN-1957 cave discovered during limestone quarrying.
1961 designated a Hokkaido Natural Monument.

Description

Tōma cave is named after nearby village Tōma. Located on the northernmost Japanese Island Hokkaido, and rather high up in the mountains, is an example for an sub arctic cave. Speleothems growth in this cave is the lowest of all Japanese show caves. The town Thoma has ski lifts and in winter the landscape is normally covered with snow.

The cave was originally named Ezo Cave or "dragon in a coil". Because the passages resembled two dragons who were huddled together in sleep. Until today there are lots of dragon depictions around the cave, although it was renamed in 1961 when it was designated a Hokkaido Natural Monument.

The cave is used to age a local specialty, sake which is named Ryunozumi or Ryo No Izumi. The Junmai Daiginjo liquor is produced by the Takasago Brewery in Asahikawa City during the winter season. The constant temperature in the cave and the mysterious power of the limestone cave bring a rich and mellow taste.
