The Dai-ichi Kangyo Bank, Limited, abbreviated as DKB (第一勧銀, Dai'ichi Kangin), was one of the largest banks in the world during the latter half of the 20th century. Dai-Ichi Kangyo Bank was created in 1971 by a consortium of two banks: Dai-Ichi Bank, Japan's oldest bank, and Nippon Kangyo Bank, a state financial institution that granted long-term loans to industry and agriculture.
