Probably not with the tourist , though all my JR ticket I have are listed with traditional date though -- maybe they issued it with A.D because of you are tourist. Other tickets seems to be mixed though. For example, of documents I have laying around my desk right now: Alien card: A.D / Student card: A.D. / My number card (like US SSN): Traditional / Insurance card: Traditional / Water bill: Traditional / Electricity bill: Traditional (this one doesn't even tell you that it's traditional, it just say 30-07-xx) / Monthly health insurance bill: Traditional / Gas bill: A.D. So it is pretty much in heavy use.
