Here in Japan, IPv6 is actually "fast" because of the network architecture.
Flets is most popular FTTH service that available nationwide by telco. Traditionally it only provides IPv4 service via PPPoE, but the architecture is inefficient and getting old so they started IPv6 service directly on Ethernet (called IPoE, a bit funny). VoIP Telephony service is also provided by IPv6 so the network called NGN.
Now the traditional PPPoE service is getting very slow due to they won't invest very well for old architecture equipment. Instead, they advice to use IPv6 IPoE for faster connection. For IPv4 connectivity, ISPs offer v4 over v6 solution like DS-Lite, MAP-E, and 464XLAT for home (shared v4 address) or IPIP for dedicated v4 address.
Many people use both IPv6 IPoE (fast) and IPv4 PPPoE (slow) because their router don't support v4 over v6, or just prefer dedicated IP for lower costs (like me), so it's important for service operator to enable IPv6 connectivity, to provide faster service. Please support IPv6!
