Thanks for your helpful reply's.
This is Adam once again Cassy has gone home. I think you guys have relaxed some of her fears about going to Japan. She has a fear of that sort of thing in just about all city's, its just worse as it tends to be a recurring theme in Hentai and what not. While it may seem relatively ignorant to base an opinion in that, however in every lie and every fantasy there is always a grain of truth, its always a good idea to see just how large that grain is.
There is no doubt that most other men will not even go so far as to look at her in the wrong way, I suspect not alot of people down there want to deal with a 260 pound angry Scotsman lol. But I to must admit, I worry about her safety when I cant be with her, as we do both have to work and its not likely we will be working at the same place and her question seemed reasonable enough, so thank you to everyone who answered this question
