Dear IPv6 Colleagues,

I, Hiroshi Esaki from Japan, have submitted response to the
case studies introducing cases of wide-area infrastructure
deployment in Japan. Some of cases uses IPv6 different from conventional  
use on the Internet.
I have picked up the following three infrastructure development.

    (1) Smart Meter, on-going
    (2) NGN IPv6, on-going
    (3) Mobile IPv6 Launch, preparing

For example for (1), it is Smart meter system for residential houses
in Japan, deployed by major electric utility companies.
Especially, TEPCO (http://www.tepco.co.jp/en/index-e.html), that is
the largest company in Japan accommodating more than 30 Million  
residential houses, and Kyushu Electric Power Company  
(http://www.kyuden.co.jp/en_index.html), that accommodates more
than 8 million residential house, has been developing IPv6 single
stack smart meter access network. TEPCO mainly uses multi-hop
wireless network with 6LOWPAN and Kyushu Electric Power Company
mainly uses 4G LTE IPv6 service for the access network.

I hope this helps!
