Although written a couple of years ago, this is excellent. It was great and still is. I love this. Jessica Korteman came to Shikoku in late 2018 and documented her experiences here. The writing is very clean and very honest. Don’t take my word for it, read on yourself!
So if you are coming in to Japan from Tokyo, spend a couple of days there and then head on West to a new and very under-explored part of the country. You won’t be disappointed!
