This was for voluntary changes, not IRROPS.Look at my previous posts for details, which surprised the experts on this board.
In cases where it is explicit, I think the rules do provide the definitive answer.
That said, I'm not aware of a rule prohibiting a "transit through Japan with flight # 12" when starting in Tokyo as you state, so perhaps the rules I refer to are out of date. (I am aware of a rule about transiting the country of origin, but it doesn't refer to Japan or a specific flight.)
In any event, what may well have happened to you having a ticket issued that is outside the rules doesn't take away from the fact that when something is explicitly prohibited or provided for, that is indeed the rule. Getting lucky doesn't somehow negate the rules carte blanche.
