Henro on Kumano Kodo - The Kumano Kodo is a network of pilgrimage routes, trekked for centuries by Japanese from all levels of society. Such pilgrims wear white and are known as Henro. The trails provide access to the Kumano region, an undeveloped area of Japan with clean river and waterfalls, pristine mountains and forests. Kumano has been sacred since prehistoric times, and is considered to be the origin of Japanese spirituality. Along the Kumano Kodo pilgrims walk through leafy paths deep into the mountains every year to purify themselves, praying to deities dwelling in the trees and rocks. Kumano is considered to be the abode of the gods by the Japanese. Thanks in part to UNESCO, Kumano Kodo networks of trails are well signposted and maintained.
