Do you have a frequent flyer program status, such as Platinum or Executive Platinum on AAdvantage program? If you have Sapphire or Emerald status on OneWorld airline frequent flyer program then you can enter Admirals Club, Sakura Lounge, Cathay Business Lounge, and Qantas Lounge at NRT Terminal 2.
If you do not have an elite status by frequent flyers program, then you have to look into Citi Prestige and Amex Plat card benefits. For credit card benefits, you have to look at your credit card benefits regarding airport lounge access. Airlines will not provide access information based on credit card benefits. Call your credit card company and ask about any airport lounge access benefit.
Saw that you posted the same question at JAL forum. Double post is prohibited on FlyerTalk... Good luck.
