Tōhoku region
Tōhoku was traditionally considered the granary of Japan because it supplied Sendai and the Tokyo-Yokohama market with rice and other farming commodities. Tōhoku provided 20 percent of the nation's rice crop. The climate, however, is harsher than in other parts of Honshū due to the stronger effect of the Siberian High, and permits only one crop a year on paddy fields.
Lilium concolor
Lilium concolor is cultivated in Japan as a food plant. The flowers, leaves, bulbs and roots are edible. Its bulb is sweet and cooling. It has starch and can be cooked and eaten as a vegetable similar to potatoes or used to make wine.
