Students in Japanese schools typically bring a packed lunch from home, called a "bento." At one elementary school, students learn while they eat, including lessons in hygiene and etiquette. "It really isn't just about eating a nutritious lunch, though that is very important of course," said principal Sumie Kato. "The children learn about appreciating their parents for providing and preparing food they are given. They learn basic etiquette, such as saying itadakimasu and goshisosama properly."
