I would say that is not just about visual kei stuff, just when it comes to cultural stuff (i guess with anime, manga and related stuff) is like they dont care about the rest of the world. For example, many dvds of movies are released without any kind of subtitles or if they have subtitle just the japanese ones, while on the other hand you have the korean example that subtitle almost every single movie, even the collections of movies from the 50-60 they release ,had subtitles. Seems like it doesn't matter to then not sell a single cd, dvd etc. outside of Japan, For the rest, I kind of agree in everything.
PS.
the OP is true...he is not like what u would expect of the typical japanese guy
