Each year, farmers in the town of Inakadate in Aomori prefecture create works of crop art by growing a little purple and yellow-leafed kodaimai rice along with their local green-leafed tsugaru-roman variety. It will be visible until the rice is harvested in September. There's a fantastic gallery of these illustrations, ranging from "36 Views of Mount Fuji" to various demons, gods and traditional illustrations, as well as the Mona Lisa.
