Asano zaibatsu

Asano Sōichirō 浅野総一郎 formed Asano zaibatsu in 1884, purchasing governmental Fukagawa Cement Works with the support from Shibusawa Eiichi 渋沢栄一 of Shibusawa zaibatsu.[1] Because Asano zaibatsu had no bank, it relied upon Shibusawa and Yasuda zaibatsu capital and was only "the 5th-largest" zaibatsu in Japan.[2] But It had 64 companies in 1940,[3] and 94 companies in 1943.[4] It almost monopolized the cement industry in Japan.[5] "Often these companies are controlled through only a minority of shares, domination being accomplished by personal influence, and the manipulation of credit, supplies and outlets."[6] Since 1945 when most zaibatsu were disbanded by Douglas MacArthur in occupied Japan, Asano zaibatsu has spun off many companies.
