Although there are many varieties of daikon, the most common in Japan, the aokubi-daikon, has the shape of a giant carrot, approximately 20 to 35 cm (8 to 14 in) long and 5 to 10 cm (2 to 4 in) in diameter. Another variety, the "Korean radish", is shorter, stouter, and has a pale green colour extending from the top, to approximately half way down the tuber.

In Chinese cuisine, turnip cake and chai tow kway are made with daikon. The variety called mooli has a high water content, and should be salted and drained before it is cooked. Sometimes Mooli is used to carve elaborate garnishes.
