Not so much for reading, but in Japan I actually saw quite a few places that were offering lessons to teach people how to become better at writing kanji, since the vast majority of communication is over phones and through computers where simply knowing the reading and having a decent idea of what the correct kanji looks like will suffice

Also in college every single one of my Japanese friends had a business keigo book they were constantly studying in their senior years to prep them for communicating in the working world.
