Ryūgashi Cavern, Natural limestone cave in Kita-ku, Japan
The Ryūgashi Cavern is a natural limestone cave in Kita-ku that extends deep beneath the surface. Inside, the passages reveal layered rock formations, flowing water features, and connected chambers that create an intricate underground system.
The cavern developed over millions of years through gradual limestone erosion beneath the ground. This slow geological process shaped the tunnel networks and chamber structures that exist today.

The cavern stays cool year-round, so dress in layers regardless of the season outside. The site offers organized tours at set times and has parking available for visitors.
Bat colonies inhabit the cavern and can be observed in their natural environment. These animals are an integral part of the underground ecology and display interesting behaviors.
