Experience alone will not be enough. Look at your own country. Could someone who didn't speak, read, or write your language be considered a safe risk for such a dangerous job? I think not.
So you "love the culture, history, and more".
1. How have you learned it?
2. What exactly about the culture do you know that you like so much? If you have never been here, that is a dangerous basis for moving to any foreign land.
3. Japan's history has been isolationistic and often brutal towards neighbors. You like that?
