What is the reason for differential treatment between foreign and local customers at Sukiyabashi Jiro? [closed]

Background:

I have watched the documentary "Jiro Dreams of Sushi" and like many others have thought about making the pilgrimage to visit the restaurant. It was interesting to read a few of the reddit posts about this place, in particular regarding making reservations and there is no doubt that opinions about this place ranges from exceptional to 'no big deal'.

I am very surprised that a restaurant rated using the Michelin star system/process can draw such a wide range of opinions when normally people would develop a consensus because the process is meant to be quite rigorous and well respected (that is my understanding anyway).

Is this really just more of a Western take on Japanese cuisine? Are there Japanese people who have been there that can provide another view on the restaurant as to its quality? If as many people claim, that there are equal or better places around, shouldn't there be lots of 3 Michelin star Japanese restaurants then?

I am curious as to why there are so many conflicting opinions about this place. Is this really just a case of fame being a blessing and curse?

Update:

After realizing how silly my original question was, I thought about the how it was a different reservation process for foreign and local customers and thought that this was a little bit unusual even for places that I have been to overseas so I want to ask if this is a typical thing at top restaurants in Japan or just because of the 'fame' of this place.
