History

I do find it a little concerning representing Hokkaido as a terra nullius, but in general I really like the article and think it's helpful for understanding cultural perceptions.

I could have sworn that Yamaga Soko, another conservative samurai writing much earlier, had a work that was literally called "bushido" or a near-equivalent, basically talking about what the samurai were supposed to do now that they generally weren't doing much fighting.

Edit: Perhaps the Yamaga Soko work in Japanese is "Bushi no Michi" or something, since the version that I have gives the title "The Way of the Knight" (which is obviously not a great way to translate the title, but the rest of the translation does not feature that weird cultural substitution that I remember).

Edit 2: I looked it up and the Japanese name is "Shido"
