Books on the Ethic/Value of “Revenge” and “Vendetta” in Pre-Modern Japanese Culture?

Hey everyone, I’m looking for books/papers that address — directly or indirectly — the issue of “revenge” in Pre-Modern Japanese culture.

Where I’m coming from is: I think it’s fair to say that there was a strong culture of “vendetta” in Japanese history. But I’m wondering how that was understood and conceptualized? For example, was it mainly understood as a “duty”(e.g., avenging the dishonor of one’s lord) or as a personal endeavor?

And, especially, to what extent was revenge/vendetta deemed noble or ennobling, lofty, worthy versus consuming, unhealthy, etc.?

In contemporary discourse the West, and in modernity, I think we have a very narrow approach to this and the notion is (basically) that all revenge is unhealthy and we ought to just go to therapy or put the wrongs we’ve suffered aside and “put it behind us.”

But here, from what I can tell, is a culture that decidedly did not do that.

Any thoughts, recommendations for study?

Secondary question: does anyone have sources for studying the interaction of Buddhism and Japan’s warrior culture? How did these coexist in the same people? Wasn’t Buddhism’s distaste for violence problematic or how was that ever reconciled?
