25 Broadband Deployment Strategy Hikari Road On March 2010, Goal of Hikari Road" Minister for Internal Affairs and Communications of JAPAN Mr,Haraguchi declared official target; * By 2015, all households use a broadband (Use rate 100%) *The number of the Japanese total households is about 49 millions. Japan aims at the realization in two directions 1Improvement of the infrastructure availability [90% 100%] 2Improvement of the Utilization [30% 100%] - Facilitate infrastructure deployment through incentives and competition - Promote public funds for unprofitable areas - Lower the service price by promoting fair competition - Create and open up new fields of broadband services by enhancing deregulation in public administration such as health care and education 25
