During my next trip to Japan I may end up in Hokkaido. I've read something about this mysterious indigenous group called Ainu/Aynu/Aino/Ezo, but I must admit my understanding of the whole thing is rather limited right now.

What I wish to know is: is there such a thing like an authentic Ainu village/town/whole-region where Ainu people live according to their tradition, as opposed to something staged for tourists?

Edit: given the comments below I wish to specify better what I mean with the word 'authentic'. Of course, I don't expect pristine landscapes and Ainu people living in blissful harmony with fluffy penguins (semi-quote) but I won't be surprised to find out there still are authentic villages in remote areas of Hokkaido where mass tourism is not an issue at all.

People are subject to tourist's attention (tourist coming from different countries, at least) everywhere, not only when they "made a conscious decision to live a traditional life". This doesn't actually mean anything. Indian people are surprisingly differents (in local customs) from Italians and Italians take a lot of pictures during their travels there, still the tourism isn't banned in India.
