This is the itinerary for my Shikoku road trip through Ehime and Kagawa prefecture that I did in spring! If you want to get off the beaten path and delve deeper into Japanese history and culture, this itinerary is a great fit for you. My time here was absolutely beautiful and I had an amazing time. I would recommend to add 1-2 days if you can to make the most out of your time here! I found 4 days in total a bit short and would recommend 6-7 days if you can spare the time. I hope you enjoy Shikoku as much as I did!
