In Fukuoka I caught 1 train and the carriage I stepped into had AO stickers and posters on it. Right avove the door as you exit, kind of hard not to miss!
You probably woudn't see much in Tokyo as we don't fly there, though that is changing now.
I am 186cms and travelled to Osaka from Cairns last year(using AO).Never again.The seat pitch was perfect for my wife.She is 165cms.
I'd be curious to know who you fly with within Australia and internationally as I thought our pitch was the same as QF and most other carriers. I'm sure you're not going to find great comfort on a seat that is even 1 or 2 inches more than us any way.
As per this link it states QF Y calss is the same as us.....it lists the seat pitch in Y class for 111 airlines.
