Negi/Japanese long onion
There are several varieties of Japanese onions, but long onions (naganegi), green onions (bannonegi), and baby scallions (asatsuki) are the most common. The green leaves are a good source of nutrients like carotene and vitamins B1, B2 and C, and also contain a digestive aid. The white part of the long onion, which generally is preferred to the leaves, should be glossy and firm. It is used in soups and nabe dishes and as a seasoning or condiment. Baby scallions, the thinnest among the onions, are usually chopped and used as a seasoning in soups and nabe (refers to a variety of communal one-pot meals) and noodle dishes.
