Nori is one of the most iconic ingredients in Japanese cuisine, often seen wrapped around sushi or rice balls. Its name has gained international recognition, and today, “Nori” is understood as a unique type of processed seaweed. In this article, we will provide a clear and thorough introduction to Nori, covering its basics, types, nutritional value, culinary uses, and storage methods for a global audience.

What Is Nori? Its Origins and Overview

Nori is a type of processed seaweed made from red algae, particularly Porphyra yezoensis or Porphyra tenera. The production process is similar to traditional Japanese papermaking: harvested seaweed is shredded, mixed with water, and then pressed and dried into thin, crisp sheets.

Although it translates to “seaweed” in English, the term “Nori” specifically refers to the dried and processed product, distinguishing it from raw marine algae. Nori has been part of Japanese culinary culture for over 1,300 years and remains a staple in daily meals and gourmet dishes alike.
