More building blocks desired

SoftBank has been in the limelight since last summer, when it bought Sprint, the third-largest U.S. mobile carrier. Now all the talk is about SoftBank also gobbling up No. 4 carrier, T-Mobile US.

     In terms of market capitalization, there is only one company in Japan bigger than SoftBank. And Toyota Motor has been around since 1937. Chairman and CEO Masayoshi Son has aggressively expanded SoftBank since its 1981 founding.

     The company started as a wholesaler of PC software, then embarked on an aggressive acquisitions strategy to rapidly expand its operations. The conglomerate is now composed of about 1,300 Internet and telecommunications companies the world over.

     Son is nothing if not ambitious. Well, perhaps a big talker, too. Both traits came through four years ago when he announced a 30-year growth plan. He sees SoftBank encompassing 5,000 companies and being among the world's top 10 corporate groups in terms of market capitalization within three decades. Toyota had better watch out.
