Softbank

Softbank is a Tokyo, Japan-based telecommunications company founded in 198 that specializes in home, cellular and internet telecommunications. This includes the manufacturing or licensing of models of cellular phones through their subsidiary Softbank Mobile. This includes the iPhone, which while made and owned by Apple, is licensed through options for its cellular service and sale by Softbank Mobile as an alternative competitive option to customers instead of Apple Stores and the stores and carriers of its competitor NTT. Softbank is the third largest company in Japan and one of the fastest growing companies in the world, with 2009 to 2014 seeing a 557% increase in capital alone.

Due to the company's prominence in Japanese telecommunications, Softbank has made its brand of phones or internet/cellular service prominent in the Kamen Rider Series when characters in the show use a cell phone to contact someone or receive a call. The company also supports the series behind the scenes, though to what extent is unknown at this time.
