Hina Sushi - is this a chain restaurant?

Well, I heard good things about Hina Sushi but when I searched, I found a number of Hina Sushi restaurants in Japan. So here I am, seeking to know if they are under a chain restaurant business model or totally unrelated outlets with similar names.

Below are some of the restaurants/outlets I found:

(1) HINAZUSHI NISHIGINZA (http://r.gnavi.co.jp/g222204/lang/en/)

(2) Hina Shinjuku (http://www.bento.com/rev/3346.html)

(3) Hina Nishi-Shinjuku (http://www.bento.com/rev/1607.html)

(4) Hina: Roppongi (http://www.bento.com/rev/0377.html)

(5) HINAZUSHI IKEBUKUROTEN (http://r.gnavi.co.jp/g222083/lang/en/)

There might be more; I don't know any Japanese and I can't seem to find any corporate information. Normally for a relatively large restaurant chain like they seem to be heading towards, wouldn't they have a corporate website or something?

Now the big question, which of these outlets are better in quality?

All of the Hina restaurants are part of Create Restaurants Group, which has 376 restaurants nationwide.

Ah, I see, so it is a chain restaurant after all. Thanks for the heads up. From your link, it turns out that there is 5 of ��� restaurants. So, the question is, is there one particular outlet that stands out from the others?

You could plug the phone numbers into the search box at http://tabelog.com/ and see which one has the highest rating.

Or you could simply go to the one that's most convenient. Oh, and I think that the prices actually vary a little bit.
