The three-way merger of KDD Corp., DDI Corp. and IDO Corp. in October will turn the new firm into a competitive mobile phone and Internet business that will enable KDD to shine, KDD President Tadashi Nishimoto says.

"KDD will play a central role in international operations," Nishimoto, 63, said in a recent interview with The Japan Times. "This is not only about fixed-line services, but also mobile services."

The three carriers, which between them possess expertise in long-distance, international and mobile communications services, are to merge into a comprehensive telecommunications company called KDDI.
