I wonder how they expect to get us to switch? Why would we want to get up control of the Internet:

Japanese communications minister Yoshihide Suga said Friday that Japan will start research and development on technology for a new generation of network that would replace the Internet, eyeing bringing the technology into commercial use in 2020. Speaking to reporters in Brazil, where he is visiting, Suga said an organization will be set up as early as this fall with cooperation from businesses, academia and government offices for promoting the technology when the Internet is seen to be faced with increasing constraints in achieving higher throughputs of data as well as ensuring data security. The envisaged network is expected to ensure faster and more reliable data transmission, and have more resilience against computer virus attacks and breakdowns.
