吉野川
Tokushima depends on agriculture, forestry and fisheries. The percentage of agricultural workers and productivity is the second largest in Shikoku next to Kochi. Rice fields occupy the lower region of the Yoshino River and the small, narrow plains along the shore. Much of the remaining land is used for vegetables and flowers. The prefecture is the nation's largest supplier of cauliflower and lotus roots, and the fourth largest producer of carrots. Japanese indigo is only produced here.
