The first reference to the Shikoku pilgrimage appears in documents from around the 12th Century; however, specific temples or route are not mentioned. The present pilgrimage consisting of the 88 temples is thought to have formed between the late 16th and 17th Century. In the modern age with the development of roads, increasingly more people are coming to do the pilgrimage either by car or bus. However, in recent years the numbers of walking (and biking) pilgrims have also been increasing.

Same practice, Two people.
What is most important is not reaching the goal, but the journey itself. The warm hearts of the people you meet and the beautiful nature of Shikoku you see will perfectly complement your action of doing the pilgrimage.
