Reason for nomination and expected role

Mr. Ken Miyauchi joined SBG in October 1984 shortly after SBG’s founding. In the course of a career focused on the fields of sales and marketing, he significantly expanded the packaged computer software distribution business that SBG was originally engaged in, and contributed to growing the domestic telecommunications business that SBG entered through acquisitions. He assumed the position of President & CEO of SoftBank Corp. in April 2015 and has led the Group’s domestic business in Japan.
SBG has elected Mr. Miyauchi as a Board Director for the further growth of the Group.

  • On October 1, 2023, Z Holdings Corporation, as the surviving company, completed an intra-group reorganization involving mainly itself and two of its core wholly owned subsidiaries, LINE Corporation and Yahoo Japan Corporation, and changed its trade name to LY Corporation.
