Background
Mitsubishi Mining was designated under the Excessive Economic Power Deconcentration Law in February 1948, and in April 1950 transferred the assets and operations of its three divisions, mining, smelting and metal processing, to a second company, Taihei Mining, which became independent. That company changed its name to Mitsubishi Metal Mining in December 1952. Shiro Yamagata joined Mitsubishi Mining in 1927, came up through this metals division, and became President in March 1960.
Selection
In March 1960 he succeeded Seiichi Komura as President. As of March 1961 the top shareholders were life insurers and trust banks, Meiji Life at 5.3%, Sumitomo Trust and Banking at 5.3%, Nippon Life at 5.0% and Mitsubishi Trust and Banking at 5.0%, while Mitsubishi Bank ranked only ninth at 1.8%. This was the structure left after the former zaibatsu holding company's stakes were released in its dissolution, and no operating company held a stake that could sway the choice of president.
Initiatives
During his tenure the company established Mitsubishi Reynolds Aluminium in January 1962 and Onahama Smelting in December 1963. While adding copper smelting capacity it entered light metals, layering aluminum on top of the three divisions of mining, smelting and processing. By 1968 all three divisions were regarded as solid pillars, and development extended from underground resources to nuclear fuel and new metals. These investments largely completed the framework of an integrated, comprehensive metals manufacturer.
