18 day Japan trip in August - in out via KIX, also Tokyo, Fujiyama, Osaka etc

Yr service looks to be very useful! Great job. :-)

So, 3 in our family - looking at the JR Pass 14 day regular Y45100. We arrive from USA on 7 Aug 3pm then head straight to Tokyo, then work our way back to Osaka, arriving back 8.20 and fly out 8.24. I note in Lonely Planet that I can pick up the pass at KIX.

My question here is: can we catch JR train straight from KIX towards Tokyo, or must take another train into Osaka first?
