It was that whole Japanese "subclass" of meat workers, who lost fingers due to their profession, that was looked down upon. So four fingers was considered a rather insulting.

That's the "official" version of the story, but really it's just extortion. Consider it this way:

You cannot publish your game in our country! Your character has four-fingers! It's insulting! However, if you pay us $5,000,000 per annum, we'll ignore the fact your character has four-fingers and everyone is happy. Especially us, because we have $5,000,000!
