0 - Using Chinese characters instead of Japanese ones all over the place
1 - Writing Japanese characters in reverse, resulting in ineligible writings
2 - Ubisoft mixing up stuff from different seasons (which bear a lot of relevance in Japanese culture), like putting grain harvest from Fall next to blooming sakura from the Winter.
3 - Stealing artwork from Japanese creators like a sword from the One Piece manga, banners from Japanese larpers, lanterns from temples without permission, figurines, etc. The list here has dozens of examples.
4 - Ubisoft putting Torii arcs as entrance to random villages, whereas
the Torii were used as an entrance to Shinto temples.
5 - Ubisoft putting burning incense in an outdoors Shinto shrine, when incense is only used inside Buddhist temples.
6 - Ubisoft putting the tatami placements wrong, in an audience where the samurai are sitting in the wrong formation and posture, in front of a daimyio who would probably kill them for it.
7 - Naoe supposedly being the furtive character walking around in the middle of a village wearing a sword on her back, which would immediately call out all attention towards her.
8 - Yasuke walking around wearing full body armor, which was only used for battle and would reallistically send villagers either running away like hell at his sight or attack him in defense. Villagers bowing to him in reverence for some reason.
Isn't your tongue dry from all that Ubisoft bootlicking?
