I am always so pleased to see more attention given to the incredible places and experiences that can be discovered in Shikoku. Here is a recent article by the Telegraph:

Tosa, Motoyama, and Otoyo are not in the media eye very often so it is great that they get some coverage for the Tosa Reihoku Festival. This looks like so much fun. I hope you can take a look at it, and when you come to Kochi consider adding some festival adventure to your journey to deep Japan.
