That Japanese flags link is a good one, I hate nationalists, but I do love a good flag.
Never knew there were so many under the Emperor and family, everyone has the same flag only they get smaller as you go down in rank to grandkid. So Japanese.. :)
Shame Japan Customs don't use their flag more often, if at all as I've never seen it. It's a brilliant design, looks like a Comme des Garcon t-shirt..
