I think there is a higher rate of crossdressers in Japan, also it's more mainstream, from musicians to TV, to prime time anime. Shopping for girl clothes here(US) you may get weird looks. In Akita, no one bats an eye. On the Oga to Akita line on weekends your pretty much guaranteed to see a group of TS, whether they are VK, or cross playing its hard to tell sometimes. I will say its more predominate among younger people.
I do agree with the height, size per region. So in the us that would be easier.
Renee, you should visit some of the TS/VK clubs then in Tokyo or hang out in Shunjuku Ni-Chome.
