Known for its spiritual pilgrimage route of 88 temples, Shikoku offers a deep cultural experience. The island’s coastal beauty is unmatched, with highlights like the Naruto whirlpools and the art-filled island of Naoshima. Matsuyama’s Dogo Onsen, one of Japan’s oldest hot springs, is perfect for relaxation. The Iya Valley offers dramatic scenery, vine bridges, and traditional thatched-roof houses. Local cuisine, including Sanuki udon, is a must-try.
