Like I said, I tried it just for fun in two different cities and airports when I was there just a few months ago, and it did not work.
I know that DoCoMo had a test GSM cell set up downtown a few years back, but it has been gone for some time. If there was ever a GSM cell at Narita, it wasn't airport wide. I walked through almost all of terminal 2 in August because I got bored of the United First Class lounge.
