GUM and
SPN
Lufthansa SG, an airline caterer on Guam and Saipan, had a lounge in both places at least in 1991 and 1992. The fee was maybe $120 per year? I still have my card, and could review my old check register, if it's that important. Upon entry, one got coupons good for two drinks, I think. Daily admission was perhaps $10. There were smoking and non-smoking sections.
I don't know when they closed -- I didn't fly much between 1993 and 1997, but by 1998 it had shut down on SPN, and the GUM location had morphed into the CO Presidents Club. Actually, the airport was re-built, so it may not have been the exact same location.
NGO
Nagoya, Japan has an airport-operated lounge. Since NW has increased flights, a WorldClub card will get you in. But not a CO Presidents Club card.
Sorry, I don't have further info, and haven't checked online.
