I'll be arriving in NRT on SK in C, and am SK*G. I'll be heading directly from the airport to a client, and so I am wondering if anyone knows of an *A arrivals lounge (I'd guess ANA, but would I have access?) in NRT, where I might freshen up - ideally getting a shower - before leaving the port?

Absent a *A arrivals lounge, do anybody know if there's anywhere in the airport (day-room, shower-room) where I could pay my way?

(I'll ask in the destination Japan forum too, in case...)
