So if I understand the wikipedia artcle about Hokkaido characters, they are not out-and-out fakes, the seem really to have been used by Ainu people, or by other who lived in the same area. But that there is argument about who used them, when and what the inscriptoins mean. Also suspiciously little info on the wiki page about how old the artificats are.
