Nippara-Shonyudo Limestone Cave

Information

Nippara-Shonyudo Limestone Cave is the largest limestone cave in the Kanto region. It is more than 800 meters in depth, about 280 meters of which is illuminated and can be explored. This vast underground space is an example of the inconceivable beauty of nature. Many of the fascinating stalactites bear their own name.
The fantastic interior of the limestone cavern maintains a temperature of approximately 11 degrees Celsius, making it feel cool in summer and pleasantly warm in winter. Formed by the slow steady trickling of droplets of water, the stalagmites in the cavern require 400 years to grow a mere 3 cm. The tour course, which has a big difference between the highest and lowest points of the course, is like a three-dimensional maze and takes about 40 minutes.
In the neighborhood of the cave are many high rocks of fantastic shapes. Located opposite Inamura Village in central Nippara, the massive Inamura Rock is known as the symbol of the region. A scenic area, formations such as Bonten Rock, Kago Rock and Tsubame Rock can also be found in the vicinity of the limestone cavern.
