	there are quite a few ISPs running IPv6 native in Japan, like:
		IIJ	http://www.iij.com/
		NTT	http://www.ntt.com/
	(yes, there are a lot more)

	vBNS seems to be running IPv6 native.

	http://www.wide.ad.jp/nspixp6/ (Tokyo IPv6 peering point)
	http://6bone.v6.wide.ad.jp/ipv6-service.html
	should give you more idea.

	at this moment it is a common practice to run separate backbone for
	IPv4 and IPv6 - because of router firmware stability reasons (for
	example, IPv6 is not available for cisco S train firmwares).
	I hope it to change sooner.
