preexisting .jp domain nameserver restriction

[kei furuuchi <kfur@example.com>]

Hello,

I said before that pre-existing .jp domain nameserver has to be
.jp domain. I found that it is  not true at all.
I don't know how I get the idea. I can't trace how I get the idea.
Sorry for my mistake and apologies for people I mislead.

Regards,
Kei.
