The seatmaps are now relatively low resolution JPEGs, and sadly you can't create high-res from low-res! I've got some old PDFs saved on my computer so PM me if you would like me to email them to you.
However, you may find
this to be more fun. It's the aircraft guide on TG's Japan website. I am certainly looking forward to the 77B!

here for the seat maps you're seeking!
wow. Thanks for the links. I didn't realise but they certainly lose a lot of seating by going to the staggered layout - down from 34J to 24J in the front cabin on the 77B (that does look exciting though!)
haven't other airlines managed to maintain the same number of J seats in the same amount of space by going herringbone or nose-to-tail (like BA/UA)?
Wonder when they're gonna start the 77b's?
