Daikon radish seeds come from the daikon plant, which is a winter radish with a mild flavor. Its name translates from the Japanese for big root. Most of the world’s daikon supply is cultivated in Japan and is consumed there as well, though the root vegetable is eaten all over Asia.

Historians believe that daikon radishes most likely originated in the Mediterranean region but that they reached Japan somewhere in the 300-400 AD period. The daikon root is ubiquitous in Japanese cooking; it is common to see it grated and used as a condiment on raw, oily fish like mackerel.

Daikon became an important part of the Japanese diet in the Edo period. It is said that daikon cultivation has saved the Japanese people from famine many times. Daikon radish seeds have a long history of use as well. They are used both as a condiment and as a medicine. The seeds have long been known to yield an oil that may be applied topically and which has healing effects.
