Yes, Radish and daikon are the same vegetables. They're both members of the family of Brassica, which also contains cabbage, broccoli, and kale. Radishes are usually smaller and more pungent than daikons. Daikons have a milder flavor and a larger, white root. Both radishes and daikons can be eaten raw or cooked. When cooked, they have a sweet, crunchy texture.
