what type of algae is nori?
While there are many different varieties of seaweeds used for consumption, Nori is by far the most commonly known and used seaweed on the market. Nori, in more technical terms, is red algae from the Porphyra genus. Japan is the major supplier of Nori, and other types of seaweed, in the world. With a lack of arable and available land to grow crops for its population, Japan has long looked to the see as a source for food.
