Japan Wireless Service Provider

Japan's Telecommunications Carriers Association shows that there are three major Japanese wireless service providers in Japan.Softbank(acquisition of Vodafone Japan), KDDI au , NTT DoCoMo. Market share ranking is as follows:

·   DoCoMo 55.7% (unchanged over March)
·   KDDI 27.8% (+0.1%)
·   Vodafone 16.5% (-0.1%).

2G subs declined for all carriers as 3G subs increased across the board with laggard Vodafone having the largest increase given it also has the lowest 3G subscriber base.

·   47.8% (+1.9% increase over Mar.) of DoCoMo subs are 3G
·   86.6% (+0.8%) KDDI subs are 3G
·   21.5% (+1.5%) of Vodafone subs are 3G

Although Vodafone was late with its 3G system, it now represents a huge opportunity since nearly 80% of its subscribers are still on 2G. With the finalizing of Softbank’s acquisition of Vodafone Japan, the big question continues to be whether current 2G subscribers will loyally migrate to 3G or jump ship for a rival carrier and if Softbank can attract new subscribers from its rivals.
