If you'll have a laptop, you can print to most (any?) 7-11 locations, which are literally just about everywhere, including inside NRT and, I believe, KIX:

A4-size pages are JPY 20 each. You make an account and can then submit things over the internet to print. When you get to the store, just enter the confirmation number you got and the printer/copier/ticket/everything machine will spit out your document.

Let me know if you need help getting through the website.

Alternatively, you should be able to use electronic boarding passes at NRT and KIX, but I'm not sure if TG offers these. I know NH and JL both do.

Thanks for that news. This is starting to sound not as bad as I feared.

cheers,

Henry

I looked around further and it appears Lawson might actually be easier (and there is one of these on the 5F of T1 at NRT, considerably easier to find than the 7-11 buried away in a train station). Rather than making an account and messing with sign-up forms in Japanese, you can simply save a PDF or JPG of the boarding pass to a USB drive and print it.

Scroll down to the section labeled: その場でメディアからプリント

The price is the same, 20 yen per page for B&W. If you want me to translate any of the instructions, just let me know. :)
