I once read this guy, an american, who worked in japan. He tried to mingle in with the crowd by talking in japanese and adapting to their customs. But guess what, they didn't like it, they prefered he stuck with he's language (english, in this case) and his ways. Once he even went for a eye check (company policy) and they machine couldn't recognise his eyes cause the machine had been done in such a way as to cater to only japanese (can't remeber the technical aspects).
The japanese mindset is very difficult to understand, that's true, but hell, if you're willing to go all the way to reach your dreams, even if there's only a chance of ony 0.02%, then go for it Suna!!.
And if this venture fails, which i hope would not, don't worry, you have us here at the forum, and i'am sure everyone would buy a copy :D
By the way, if you're looking for a manga artist, forget me, i suck at it, can't even draw my cat. Though at one time i did dream of being one :D
