Shikoku 四国 is an oft-forgotten island in Japan. The smallest of Japan's Big Four, it lies to the south of Honshu. The island is thought of as a rural backwater, with few must-see attractions, but a visit there can wash away those doubts; the mountainous inner regions offer some good hiking. It is also the home of the 88 Temple Pilgrimage of the Shingon sect of Buddhism.
