Kin-game rice is said to be richer in vitamin B1 and vitamin E, as well as dietary fiber, than conventional white rice. It is also low in calories, and is even used at the Tanita Restaurant in Marunouchi. The Kin-game rice used in "One Piece Rice" is made from "JA Shinshu Miyuki Gen-no-mai," a high quality rice that is harvested in small quantities and is very rare.
Well, it looks like the only way to get this One Piece rice for now is to purchase the Premium Set, which includes a rice scoop with the character's pirate flag mark and a lunch bag, at the Dinos Online Shop.
But it seems that it will gradually become available at convenience stores and supermarkets across the country. Let's hope for the best!
