All Nippon Airways Mileage Club - UA to NRT then ANA to BKK!

I'm flying LAX into NRT on UA-f into terminal 1 then fly out of terminal 2 on ANA in B-class! A few things...after I exit the plane I go through security and can shower in Uniteds Lounge right! After shower head to Terminal 2 to signet until my flight boards! I'm gold and on an upgraded biz ticket! Can I use United's F-lounge in NRT before I head to terminal 2 or do I have to just use the gold lounge...or am I unable to use any of terminal 1?

UA's F lounge requires an invitation. I don't think you would have access there if you are flying business or are you a UGS?

I think it might be better to pose this question in the UA forum. There are lots of more people reading there.
