Nintendo has an official clause in its contracts that stipulates any Japanese developers or publishers it works with cannot be tied to organised crime groups such as the Yakuza.
Documents and details about the inner workings of the games industry are currently being revealed as part of the ongoing Epic Games vs Apple trial. A highly confidential and heavily-redacted Nintendo document has been doing the rounds as a result. Within that document is a section on "Anti-Social Forces," spotted by Stephen Totilo of Axios Gaming.
The document notes that if a 'Content Provider' is based in Japan, it can not be an "Anti-Social Force" or "Boryokudan" (a Japanese term that means 'violence groups', or organized crime groups). Effectively, the document imposes a black and white ban on partners working with the Yakuza.
