Limestone Rock Cliff and Hand-Drilled Tunnel of Odahara

Basic points

This spot, which is located at the entrance of Otaki District of Chichibu City, forms a rugged terrain consisting of limestone body scattered on the hard stratum of Chichibu belt, and it blocks the passage of people. Here, there is also a hand-drilled tunnel, in which people drilled the limestone body at the end of the 19th century.
The large tunnel is roughly 40m in length and 4.8m in height, and it played an important role as a pilgrimage route to Mitsumine Jinja until a national highway (the current Japan National Route 140) was made in 1921.
