Last month I flew CX J, was refused entry to all JAL lounges in the terminal at NRT. Was told to use CX lounge due to capacity / renovation. I had 5 hours coming in from NGO. Was surprised AA was really good. CX was nothing to write home about. Did not check out QF as my travel companion was complaining about the long walk to get to all these lounges.

Priority Pass only gets you access to LAND side lounges. Small crowded seating typical of Japanese lounges. You get 1 free alcohol drink at IASS lounge, or 0 at TEI lounge. Haven't visited them for ages.
