The Oxya yezoensis is a pest from Japan that feeds on rice plants in the paddies. It became a source of protein and calcium in inland areas of what is now known as Nagano Prefecture and was cooked in a variety of ways including skewered over a fire, or cooked with soy sauce and sugar. Eating these bugs was especially common after World War II due to food shortages and is depicted in the manga "Barefoot Gen." Inland Japan never sees natural swarms of these grasshoppers due to geological conditions.
