Im glad you asked. They have:

• Misrepresented the role of the historical dude (and other historical characters), but we can ignore it since it's just a fantasy game where you punch the Pope in the face. Even though their marketing guys insisted a lot on historical accuracy...
• Used elements from Chinese architecture and south east Asia, because that's all the same, right?
• Copied flags from a Japanese historical reenactment society without permission.
• Published promotional material with the design copied from One Piece.
• Also, promotional material using the famous Torii Gate that survived the Nagasaki bomb (more insensitive that actually racist).
• Included a real shrine with its real name (again, without asking permission) and made the environment destroyable (while other locations are indestructible?). This is what sparked national outrage that reached the parliament and forced a day 1 patch.

I'll gliss over the rest of the historical inaccuracies because, again, it's a fantasy game in the end.

If you don't see any racism and general disrespect for the Japanese culture (which they have supposedly accurately researched), It's like I said: rose-tinted glasses.
