Polaris with the new seats is still very limited. 777-300ER is your best bet right now. I think there is one 767 in service right now with Polaris seats.
SFO-NRT is pretty much your only bet for the new seats. Only other options would be SFO-HKG or SFO-TPE and fly ANA up. Only ORD has new Polaris lounge right now and I'm not sure PHX-ORD-SFO-Asia even works for your trip.
I'd just go ahead and do PHX-SFO-NRT. Unless you want to try ANA from HKG or TPE and spend a night in one of those places. Not sure why you'd want to do that though, I wouldn't.
Your options are limited and best bet is SFO-NRT. Good luck.
