Ehime Prefecture Essentials

Ehime Prefecture features a distinct blend of feudal history, spiritual heritage, and coastal geography. The region is home to Matsuyama and Ozu Castles, notable for their rare original and authentically reconstructed timber keeps. Spiritual traditions are anchored by the Shikoku 88 Temple Pilgrimage, including the remote mountain sites of Daihō-ji and Iwaya-ji. Modern landmarks like the Shimanami Kaido’s island-hopping bridges and the French-style Bansuiso villa complement natural sites such as Cape Sada, the westernmost point of Shikoku.
