Nozawana

From Freepedia

A nozawana (野沢菜) is an edible Japanese radish, often pickled. Its leaves are approximately 60-90cm long.

Sometime between 1751-1764 it was taken by a person who lived in Nozawa from the Kyoto mountains to the Nozawa hot pool village. It was cultivated around that area, and thus named Nozawana. Na means plant in Japanese.
