I know it's blurry, but the area I circled on the building; There's no way that's the english language. It's very square, like kanji (or korean?). But since it's so blurry, it might also have kana that we can't see. We'll have to wait for credits or until a better quality version comes out.

(I circled it, it's in the top left corner.)

Also take note of the mailbox. U.S. mail usually has the eagle on it, which is not visible in this photo.
