Any way to get in to the sociolinguistics side of Japanese politeness?

Hey, sorry if this is not as suited for the subreddit, but I figured it should be fine to ask this here.

I'm really into linguistics, and one thing that really caught my attention with Japanese is the sheer amount of nuances that are carried in the sentence, specifically concerning politeness/formality.

I'm really no expert on the subject at all, but Japanese culture seems very heavy on hierarchical relations, e.g. you have to be really respectful with your boss, and the language expresses that.

And I wonder if the language became so respectful-ish because the culture relies on that… or one thing reinforced the other? And for either case, I would wanna know why is that.

I searched and the most relevant book I could find is called "The Japanese Mind", but I feel it does not dig in to the linguistics aspects I would wish for.

Does anyone have recommendations on what I could look into? Anyone ever got curious about the same topic? Not quite sure where or what I should look for, tbh.

Just to be clear, I don't want to specifically learn Keigo, I want to know more about the questions I mentioned earlier. Thanks 🙂 good 勉強 for everyone
