Whatever the religion or whoever they're devoted to, shrines have a way of making you reflect. Check out Oohito Shrine and share a quiet moment with the faithful.
When you've finished at this sacred place in Izunokuni, why not make your way to Izu-Mito Sea Paradise, Shuzenji Temple, and Awashima Marine Park? They're not very far from Oohito Shrine and also popular with many tourists.
