Burger chain Lotteria Corp is selling a new type of french fried potato. The Marugoto is a whole potato divided into wedge-shaped parts. Lotteria said it is using Hokkaido potatoes and Japanese salt to suit the taste of Japanese consumers. It is the first company in the fast food industry to use potatoes grown in Japan. Lotteria officials say they are hoping to help increase Japan’s food self-sufficiency rate by using potatoes grown in Japan.
