I get a kick out of your "I'm huge in Japan.."
I lived there working overseas for Sperry/Univac (eventually Unisys) for 10 years. At 6' 2", I was definitely huge over there!
I'm half Korean...but pretty big build all in all compared to most in my family and friends I grew up with. 6 ft and I was about 314lbs when I started saying that. Now I am down to about 236. So not as big...but still big enough. lol
