Kombu

Konbu (from Japanese: 昆布, romanized: konbu or kombu) is edible kelp mostly from the family Laminariaceae and is widely eaten in East Asia. It may also be referred to as dasima (Korean: 다시마) or haidai (simplified Chinese: 海带; traditional Chinese: 海帶; pinyin: Hǎidài).

Kelp features in the diets of many civilizations, including Chinese and Icelandic; however, the largest consumers of kelp are the Japanese, who have incorporated kelp and seaweed into their diets for over 1,500 years.
