>>113986182Essentially, yes. Just like the original code of chivalry from the medieval to Renaissance period, bushido was originally a rough guideline for a quasi-hereditary warrior class on the rules of engagement, and how that class should conduct itself with the proper subservient attitude in regards to their social betters. In the aftermath of the climactic battle of Sekigahara and the peace of the Tokugawa shogunate, bushido was expanded on to include these ritualistic, semi-spiritual airs. You know, stuff like 'the sword is the soul of the samurai', etc. Much, much later on, and I mean close to the end of the 1700s and only 50 years before Commodore Perry would arrive in Edo Bay with his black ships, hack novelists and playwrights would expand on that theme to codify Bushido with a capital B as some uniquely Japanese cultural thing.
>>113986270I can't point to a specific example, it's just a general running theme in all of UY. I'm not saying that's a bad thing, or that it detracts from the narrative, mind. It'd be like complaining about how a spaghetti western isn't like what the real Wild West was. Usagi Yojimbo is a work of meticulously researched historical fiction, but it's also a genre piece, and that genre has certain assumptions and trappings that aren't historically accurate but are culturally valid, if that makes sense.
