Thank you for the response. What type of written proof would do? My bills to proove address where I live? My Brazilian passport with all stamps in it?

Thanks for the assistance.

The best would be government issued documents showing that you have permission to love long term outside of Japan. You will need your passport of course but better to bring both that you have along with copies of anything you can think of that would show you are not living in Japan.
