Nori is a Japanese word for edible seaweed that is shredded and dried into sheets, in a process similar to making paper. It is usually toasted.

A rich source of protein, vitamins, calcium, iron and other minerals, nori is produced in Japan, Korea and China and is most commonly used as a wrapper for sushi. The seaweed is crunchy when dry but quickly becomes soggy once it comes into contact with damp sushi rice. Nori can also be cut up into fine strips and added to miso soup or noodle dishes.
