The part where they feel the need to point out that shoplifting is a crime is a bit condescending, but if a polite pamphlet is the worse form of discrimination you're facing in Japan then you should probably not complain.
You would think that, but I did study abroad years ago in japan, and some guys got deported for shoplifting. Another guy I knew there also had a very liberal attitude toward property ownership (as in, if it wasn't locked up, the original owners must not care about it), but never got caught.
This is downright friendly. TL;DR: Here are basic norms, laws, and some common scams, please be aware.
