Yes, it is because it is a Japanese company. This game was, initially, made for the Japanese people. Also, though, since the Japanese servers can be played on by those of us not in Japan, I think it's a type of fairness. If one set of servers can't play, then neither can the others. It's only two hours...at least it's not 8.

I also agree with Remilia. It is not just us 'NA customer base' that is getting it, it is the whole customer base, including Europe.
