Uwajima

By train

Uwajima is the western terminus of the JR Yosan Line 予讃線, and there are regular connections north to Matsuyama. Normal trains from Matsuyama cost ¥1750 and take 3 hours, with at least one change of trains required. The Uwakai Limited Express adds a ¥1660 surcharge, but shaves the travel time down to 75-80 minutes by not stopping at every rice paddy along the way.

Okayama is about 4 1/4 hours away via two limited express trains, the Shiokaze and the Uwakai, changing trains in Matsuyama ¥8520.

Infrequent trains on the JR Yodo Line 予土線 also connect Uwajima to Kochi, but you'll have to transfer at JR Kita-Uwajima Station, one stop north of the city center.

By remarkable coincidence, buses from Matsuyama to Uwajima also cost exactly ¥1750, but are a little faster than the regular trains.
