The or is a multi-site pilgrimage of 88 temples associated with the Buddhist monk Kūkai (Kōbō Daishi) on the island of Shikoku, Japan. A popular and distinctive feature of the island's cultural landscape, and with a long history, large numbers of pilgrims, known as , still undertake the journey for a variety of ascetic, pious, and tourism-related purposes. The pilgrimage is traditionally completed on foot, but modern pilgrims use cars, taxis, buses, bicycles, or motorcycles, and often augment their travels with public transportation.
