Bento in farming areas "Edo Meisho Zukai"
Collection of Oe Library, Tokyo Kasei Gakuin University "Edo Meisho Zukai" depicts the farming areas in the Edo period. In the book, there are pictures of farmers eating Bento as their lunch in the countryside. It is believed to be around today's Kanazawa Bunko in Kanagawa Prefecture. One of the pictures show rice balls packed in one tier of lunch boxes and chopsticks in another tier. That suggests Nishime, vegetables and chickens cooked in broth, soy sauce, sugar, sake and sweet cooking wine, and pickles are packed as well.
