If you are considering coming out to Shikoku to experience the 88 Buddhist Temple Pilgrimage, a documentary you might consider checking out is this one:

 

 

It is the episode of the television series, Sacred Journeys, which takes place all over the world and is an exploration of different kinds of journeys and pilgrimages, discussing the purpose, the journey, and those who travel these paths. This episode is quite well done and it is a good representation of what you may see should you come out this way. It is a bit long, so get yourself a cup of tea, settle in, and enjoy.
