What we call the senary industry, where produce is not only sold by entrusting it to market circulation, but also directly sold to consumers, provides benefits to producers, and also leads to the revitalization of the primary industry. In the "light truck market," among others, people can open a shop easily as they can carry their goods to the venue by putting them on the deck of the truck and sell them directly, which has made demand increase nationwide. However, there is no specifically designed system, where light trucks only carry goods and most people open a shop using a tarp tent for family use and a foldable table. We thought that supporting producers to open a shop, through developing a simpler product with high designability, could lead to further revitalization of the senary industry as well as regional revitalization.
