7 Strengthening Our Network as an ICT Platform in Tourism Locations Easy Connections Even at Japan’s World Heritage Sites, Natural Treasures and Tourism Locations, Like the Upward Path and the Summit of Mt. Fuji, the 88 Temples in the Shikoku Pilgrimage, from Shiretoko in the North to Ryukyu Kingdom artifacts in the South *Depending on signal conditions, even within the LTE area communications may be via 3G or in some cases, not available. *Clockwise from upper left, Mt. Fuji, Ryozenji (sacred places of Shikoku), Oshinkoshin Falls (Shiretoko, Hokkaido), Tomioka Silk Mill, Shirakawa-go, Shurijo Castle Park (Okinawa) ©Shobunsha

9 Our Business Challenges

10 Japan Dynamic Mobile Market Total of Mobile Subscribers in Japan SoftBank Mobile NTT Docomo Market Share au subscribers 40 million

11 (Gbps) Source：Ministry of Affairs “ Domestic Mobile Traffic Trend”, June x Just in 2years( ) Explosion of Mobile Data Traffic Domestic Average traffic / month Source: KDDI Financial Statement in March, 2014 and in March 2013 au smartphone shipments(000’s)

12 Traffic Pattern Different Peak by area  Load for authentication and billing systems will change by time

13 Burst of Traffic Earthquake Morning Alarm Morning Alarm 3x

14 Our Project Goal 1 Enhancement of systems for Authentication, Subscriber Database 2 High Availability to provide stable, high quality services 3 Flexible, high cost-performance platform for future enhancement Challenges: How we can manage huge traffic? How we can prepare future traffic growth?
