A Food Deeply Rooted in Japanese Culture
By the Edo period, advances in aquaculture allowed nori to be produced on a larger scale. It became a food for the common people and, today, it is an everyday essential on Japanese dining tables.
Nori belongs to the red algae family Porphyra, with about 30 edible species. In Japan, most cultivated nori comes from Susabi-nori, though varieties like Asakusa-nori and Kaigara-ama-nori are also known.
