This is really Shikoku Pilgrimage Youtube gold for walking pilgrims in Shikoku. The creator, atsushi ASH, did an amazing job in documenting his 42 day trek around Shikoku. His documentary starts from Kanto and then comes to “The Pure Land”. The entire thing is in Japanese, but just switch on the English subtitles and enjoy the journey.
If you would like to follow Atsushi-san on his adventures please also check out his blog of his cycling journeys in Japan too! http://nippon-around.blog.jp/
