He purchased from the government in 1884 (Asano Cement), with help from Shibusawa Eiichi, founded Iwaki Coal Mine in 1884, Oriental Liner (Toyo Kisen) in 1896, Tsurumi Reclamation Company (Toa Construction Corporation) in 1913, Asano Shipbuilding and Engineering (Japan Marine United) in 1916, Nippon Chuya Bank in 1916, Oki Electric Industry in 1917, Asano and Company in 1918, Asano Holding Company in 1918, and diversified his business interests, which eventually became a minor zaibatsu (Asano zaibatsu). His Nippon Chuya Bank was unsuccessful, so he sold it to Yasuda zaibatsu in 1922. Asano zaibatsu kept minor because it did not include a bank and was ranked fifth in scale. Asano is called "the cement king."
