I see no reason to believe you'd have to wait until Japan to make any date changes. Ask the person saying so for a citation from the rules. If you don't have a copy of the rules yourself, now's a fine time to get them.

I was told this by a JL agent; while I am of course prepared to pay the SIN taxes, repricing the itinerary will cost me a lot since the ticket was purchased nearly a year ago and at a time when the fare was MUCH lower than today's fare!
