fun fact: While some foreigners who brag about "knowledge" of Japanese history, learning from Kurosawa films, criticize portrait of "pride" samurai in Ghost of Tsushima, JP people jokingly dissatisfied with the game 'cause samurai in Kamakura period should've even more barbarous.

These days Kamakura Bushi have become vicious heroes in JP subculture because academic studies have revealed they were ridiculously short-tempered and did anything to kill without hesitation.
Google suggests it with "barbarian," which demonstrates we enjoy their dirty behaviors.

Kamakura bushi became happy with beggars passing by because they were suitable for living targets of lethal arrows.
So when Mongolians bound Japanese captives to their shields, no samurai cared about their compatriots, harshly shooting arrows at them.

Most Japanese know so-called Bushido (the way of samurai) was merely a set of moral codes for govevnment workers in Edo period. We learned it from a rich variety of historical (sometimes vulgar) dramas, films, animes, mangas, novels, and games, not only from "good taste films."
