Zaibatsu (財閥, "financial clique") is a Japanese term referring to industrial and financial vertically integrated business conglomerates in the Empire of Japan, whose influence and size allowed control over significant parts of the Japanese economy from the Meiji period until the end of World War II. A zaibatsu's general structure included a family-owned holding company on top, and a bank which financed the other, mostly industrial subsidiaries within them. Although the zaibatsu played an important role in the Japanese economy from the 1860s to 1945, they increased in number and importance following the Russo-Japanese War of 1904–1905, World War I and Japan's subsequent attempt to conquer East Asia during the inter-war period and World War II. After World War II they were dissolved by the Allied occupation forces and succeeded by the keiretsu (groups of banks, manufacturers, suppliers, and distributors). Equivalents to the zaibatsu can still be found in other countries, such as the chaebol conglomerates of South Korea.
