The reason Tokyo dosn't have the articulated heads, is probably the same reason they don't have a lot of the newer characters. Tokyo only gets new characters, when their movies are a big hit and even then they don't get a M&G. For example, the Frozen characters didn't appear till 2015 and they have never met. Nick and Judy are debuting in a parade in a couple of days, but they won't be meeting (at least for now). Any character that debut after 2005 dosn't appear in the Tokyo parks, exept Rapunzel,Flyn and possible on or two more. Even characters pre 2005, only appeared if the film was successful. Don't know why this is the reason, as they don't need to get a face character preformer for the furs. A possile reason could be that they are waiting for them to debut the new style heads, before they get the articulated ones, therefore not 'wasting' old heads.
