Relief map of Shikoku

Shikoku is the smallest and poorest of the main Japanese home islands, with an area of 7247 square miles (18,770 km2).  The island is very mountainous, hindering communications and agriculture, and has no large natural harbors

Unlike the other islands, Shikoku has no volcanoes, but there is a large copper mine at Besshi.  The main products of the island are agricultural: rice, grains, camphor, and mulberry.  There is also fishing and salt production. Most of the population is located on the northern coastal plain, including the largest city, Matsuyama.
