Ao-no-domon (Tunnel dug through the Kyoshu Peak)
Ao-no-domon (青の洞門, Tunnel dug through the Kyoshu Peak) is a nationally famous historic site. In the Edo era this was the only way to Rakanji Temple. But the way was very dangerous, so, a monk known as Zenkai spent 30 years digging this tunnel through the Kyoshu peak using just a chisel and a hammer. The tunnel is also well-known from Kan Kikuchi's famous novel, "Onshu-no-Kanatani".
