Saccharina japonica
Template:Short description Template:Speciesbox
Saccharina japonica is a marine species of the Phaeophyceae (brown algae) class, a type of kelp or seaweed, which is extensively cultivated on ropes between the seas of China, Japan and Korea.[1] It has the common name sweet kelp.[2] It is widely eaten in East Asia.[3] A commercially important species, S. japonica is also called ma-konbu (Script error: No such module "Lang".) in Japanese, dasima (Script error: No such module "Lang".) in Korean and hǎidài (Script error: No such module "Lang".) in Chinese.[3] 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][4]
The species has been cultivated in China, Japan, Korea, Russia and France.[5] 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.[6]
S. japonica contains very high amounts of iodine. Excessive consumption (15 g/day, containing 35 mg iodine) suppresses thyroid function, though thyroid hormone levels remain within normal limits.[7]
Nomenclature
The species was transferred to Saccharina in 2006.[8] 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).[5]
Cultivation
Over 90% of Japanese kombu is cultivated in Hokkaidō. With the development of cultivation technology, production can also be found as far as south of the Seto Inland Sea.

In Chinese cuisine, sliced kelp is a common hors d'oeuvre which is often consumed with alcohol.
Korea
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.
One of Nongshim's instant noodle, the Korean original versions of Neoguri, contains one (or rarely more) big piece of dasima in every package. Odongtong Myon, Ottogi's copy of Neoguri, also has big piece of dasima in every package - Ottogi uses 2 dasimas since 2020.[10]
