As the title says...we are on a long layover in NRT. My ideal would be to drop by the SkyClub, grab a shower and freshen up, then head into Narita for shopping and food. While I've transited NRT many times, I've never tried this particular flavour and can't find reference to it here.

So, does anybody recall how one can make the path from the lounge to arrival immigration? In HK there's a "secret door" that can get you through between arrivals and departures, but it's definitely a non-standard path. Am I better off giving up on this idea entirely, or is there a way to do it at NRT that I'm forgetting?
