Shikoku しこく (四国) is the smallest of Japan's four main islands.[1] About 4 million people live there, fewer than on any of the other main islands.
The island lies south of Honshu[2] and east of Kyūshū across the Kanmon Strait. A bridge connects it to Honshu.
Farming is a very important business in Shikoku. Citrus fruits are an important product. Shikoku is the home of the 88 Temple Pilgrimage of the Shingon sect of Buddhism.
