Shimanto Connects Takamatsu (高松) with Kochi (高知), Nakamura (中村) and Sukumo (宿毛). Nanpu depatrs from Okayama to Kochi, Nakamura and Sukumo via Seto Ohashi bridge (瀬戸大橋). Most of these trains are combined to operate between Utazu (宇多津) and Kochi, Nakamura and Sukumo. These trains are operated on Non JR line, “Tosa Kuroshio Railway” between Kubokawa (窪川) and Sukumo. If you take these trains on this section, you need to pay some extra. I will show you the extra fare below.
