The Henro Michi is one of the oldest and most famous pilgrimage routes in Japan. It consists of a circuit of eighty-eight temples around the perimeter of Shikoku, the smallest of Japan's four main islands. Every henro, or pilgrim, is said to follow in the footsteps of Kōbō Daishi, the ninth-century ascetic who founded the Shingon sect of Buddhism.
