Ehime Prefecture occupies the northwestern corner of Shikoku island, facing the Seto Inland Sea. Known for Matsuyama Castle, the oldest operating hot-spring bathhouse at Dogo Onsen, the pilgrimage temples of the Shikoku 88-temple circuit, and the nation's finest mandarin oranges, Ehime blends samurai history with coastal scenery and one of Japan's most genuine onsen cultures.
