We go to Kawaguchi City, near Tokyo, to visit a company that boasts the biggest share of cardboard boxes in Japan. Cardboard boxes come in a variety of types, as different clients demand different features. Designers at the packaging technology department work restlessly to develop boxes, but when they get hungry at lunchtime, they eat heartily at the cafeteria. In another segment, we go to Fukuoka Prefecture, southwest Japan, to meet a group of men who are farmers by day and handball players by night.
