If I'm wrong about the Terminals then please accept my apologies. To my eyes T1 has looked decades newer than T2 for years now and the difference is never more striking than seeing them back to back with one of those old school bus transfers. Seriously, NRT's T2 looks very old to my eyes. What's odd is that the NAA lists the grand opening of T1 as June 2nd, 2006 (Page 7 from the 2006 edition of the "Narita Airport Guidebook A to Z Terminal 1"). I guess they're talking about the recent musical chairs renovation work because we all know that T1 was up and running long before that.
