Adzuki Bean

The adzuki bean (Vigna angularis; from azuki (Japanese: アズキ（小豆）), sometimes transliterated as azuki or aduki, or English red mung bean) is an annual vine widely grown throughout East Asia and the Himalayas for its small (approximately 5 mm) bean. The cultivars most familiar in Northeast Asia have a uniform red colour, however, white, black, gray, and variously mottled varieties also are known. Scientists presume Vigna angularis var. nipponensis is the progenitor.
