Sweet potatoes consumed as food crops have a higher degree of sweetness and moisture, with the Beniharuka being a mainstream variety. Other varieties, such as the Ayamurasaki used in processing (as a purple dye) and the Koganesenkan used for brewing, are also cultivated locally.

A new local brand, the Kanta Kun is a variety of sweet potatoes possessing intense sweetness and a creamy texture. To enhance its already high sugar content, the Kanta Kun is put into dark storage for at least forty days after they are dug out of the earth, and subsequently undergo thorough testing for sugar content levels. 1.5 times sweeter than common sweet potato varieties, the Kanta Kun oozes a glistening, honey-like glaze when it is roasted.
