[4] White adzuki bean powder (geopipat-gomul) and white adzuki bean paste (geopipat-so) made from husked black adzuki beans are used in Korean rice cakes and confections.
[5] Confusingly, the Japanese Okinawan kuroazuki (黒小豆; "black adzuki beans") are not adzuki beans, but black cowpeas (Vigna unguiculata).
