Saccharina japonica is a marine species of the Phaeophyceae (brown algae) plant, a type of kelp or seaweed, which is extensively cultivated on ropes between the seas of China, Japan and Korea.[1] It is widely eaten in East Asia.[2] A commercially important species, S. japonica is also called ma-konbu (真昆布) in Japanese, dasima (다시마) in Korean and hǎidài (海带) in Chinese.[2] Large harvests are produced by rope cultivation which is a simple method of growing seaweeds by attaching them to floating ropes in the ocean.[1][3]

The species has been cultivated in China, Japan, Korea, Russia and France.[4] It is one of the two most consumed species of kelp in China and Japan.[1] Saccharina japonica is also used for the production of alginates, with China producing up to ten thousand tons of the product each year.[5]

Consuming excessive S. japonica suppresses thyroid function.[6]


The species was transferred to Saccharina in 2006.[7] Three synonyms for this species name are Laminaria japonica (J. E. Areschoug 1851), its variety Laminaria japonica var. ochotensis (Miyabe & Okamura 1936) and Laminaria ochotensis (Miyabe 1902).[4]


With the development of cultivation technology, though over 90% of Japanese kombu is cultivated mostly in Hokkaidō, production can also be found as far as south of the Seto Inland Sea.

Culinary use[edit]


In Korean cuisine, dasima is used to make broth, deep-fried into bugak or twigak (coated and uncoated fries), pickled in soy sauce as jangajji, and eaten raw as a sea vegetable for ssam (wraps).

It is also used to make dasima-cha (kelp tea).

Cheonsa-chae (kelp noodles) is made from the alginic acid from dasima.
