Especially, the kind without the pharmacologic action is called an "Industrial Hemp" by the fiber type. Hemp is sold to clothes, food, cosmetics, paper, construction materials; the car interior material, the fertilizer, and horse's bed, etc. in EU nations, and the market has expanded. This plant decreased sharply by the restriction of Cannabis Control Law and the spread of the artificial fiber in Japan after World War II. It is being used only for a special usage for the divine service etc. now. Recently, the possibility of Hemp is expected as a resource crops in Hokkaido and Nagano Prefecture, etc. where the cultivation license was new and permitted for the first time after the war.

I can be larger than other farm products amount for each unit, and use the cascade with one crops. This research set three case studies, and compared the economies.
