關原鍾乳洞, Solutional cave in Sekigahara, Japan.
Sekigahara Stalactite Cave is a limestone cave that extends roughly 500 meters beneath the surface. Inside, mineral formations shaped by water seepage create a network of chambers with stone pillars and hanging deposits.
Explorers found the cave in the early 1900s near a location that shaped Japan's political course. The area surrounding it played an important role in the nation's transition to a new period of governance.
Local guides share geological knowledge while leading visitors through illuminated chambers where rainbow trout swim in underground spring water.
The cave stays at the same comfortable temperature throughout the year, so you can explore without worrying about seasonal changes. The passages through the illuminated sections are manageable for most visitors and require only a short amount of time.
Rainbow trout swim in the underground spring water, thriving in complete darkness within the cave system. Few visitors expect to encounter living fish while walking through the stone passages.
