Toma shonyudo, Limestone cave in Hokkaido, Japan.
The cave system extends through five chambers over 135 meters, displaying natural limestone formations shaped by underground water effects.
Workers discovered the cave during limestone quarrying operations on January 13, 1957, leading to its designation as a Hokkaido Natural Monument in 1961.
Local sake producers age their Ryunozumi liquor within the cave, utilizing its constant temperature and limestone environment for optimal fermentation.
The cave welcomes visitors from May through October between 9 AM and 5 PM, with entrance fees of 500 yen for adults and 300 yen for children.
The cave passages form a pattern resembling two dragons huddled together, earning it the initial name Ezo Cave and inspiring dragon-themed decorations throughout.
