Ao no Doumon

Ao no Doumon

青の洞門

During the Edo period, a Buddhist monk named Zenkai seeks to atone for a murder he committed in his earlier life. He learns that pilgrims must cross a dangerous cliff path to reach an important local shrine, and many have fallen to their deaths. Determined to create a safe passage, Zenkai begins digging a tunnel through the rock by hand, using only a hammer and chisel.

Starting at the age of 49, Zenkai dedicates himself to this monumental task for 30 years. The 185-meter tunnel, known as Ao no Doumon, becomes his life's work and a testament to his repentance. As he chips away at the stone, he faces physical exhaustion, isolation, and the weight of his past, but his unwavering resolve drives him forward.
