This paper will clarify the business model targeting a successful company called Softbank. Softbank has attracted the attention of many people during the domestic recession because the company has made a remarkable growth (about 3 trillion yen), ranking among the top 10 with in the domestic market capitalization, as of June 2011. Once a mere venture company, it surpassed Panasonic and Sony, playing a lead role in 30 years. What is the strength of Softbank? Does the Softbank growth imply the transformation of a Japanese-style management? I would like to collect data and study the business model to indicate ways for management of Japanese and Taiwanese companies for the upcoming future.
