Unless you have connecting flight where you can get the boarding pass at check-in there, you will indeed need to wait until the JAL counters open 3 hours before departure.
If you are travelling carry-on only, you might be able to use a boarding pass from online check in, though I have not tried if it is actually possible to get a boarding pass at OLCI for JFK departures
