Nori (海苔) is the Japanese name for edible seaweed species of the red algae genus Pyropia, including P. yezoensis and P. tenera. Nori is familiar in the United States and other countries as an ingredient of sushi, being referred to as "nori" (as the Japanese do) or simply as seaweed. Finished products are made by a shredding and rack-drying process that resembles papermaking.
