If you are carry-on, no problem, but as it sits right now if you have checked luggage, you can't enter Japan to retrieve it, so it all depends on if ANA will check your luggage through on JAL, which is probably unlikely, or if Japan loosens controls and allows you to enter and collect luggage by late June. For checking bags through, you will have to ask ANA, I think the best way to know is to make a trip to ORD while the ANA gate is open and ask if that's something they are able to do, I wouldn't trust the phone agents for something like this.
