The issue with this article, and possibly the game, is that it conflates two distinct cultures. While Western countries may not place as much importance on tradition, the Japanese hold it in high regard. Imposing Western perspectives on Japanese culture is likely to be poorly received.
Samurai were Japanese warriors bound by bushido, serving local lords and the Shogunate. In contrast, the Ainu had their own cultural system centered on hunting, fishing, and animistic beliefs, entirely separate from Japan’s feudal structure. Although they had warriors, they were not part of the samurai class.
The Ainu didn’t have samurai because they were not part of Japan’s feudal system and had their own distinct societal structure. Attempts to merge these two separate cultures could lead to further controversy.
Stop conflating cultures—this won’t deceive anyone, least of all the Japanese, and could provoke controversy. Samurai were Japanese warriors bound by bushido, serving local lords and the Shogunate. The Ainu followed a separate cultural system based on hunting, fishing, and animistic beliefs, remaining outside Japan’s feudal structure. While they had warriors, they were not part of the samurai class.
