Loved it. This is some necessary background that helps me contextualize a few other oddities of the time period that I have had floating in my short term memory - Miyamoto Musashi (d. 1645) - Tsujigiri, random slashing of bystanders - the Great wave off Kanagawa, painted towards the end of the Edo period - Shinobi evolving from mercenaries into secret police
>Tsujigiri (辻斬り or 辻斬, literally "crossroads killing") is a Japanese term for a practice when a samurai, after receiving a new katana or developing a new fighting style or weapon, tests its effectiveness by attacking a human opponent, usually a random defenseless passer-by, in many cases during night time.
I know it's tragic but this sounds so absurd it just made me laugh. They were on some good shit.
