It's bold of the Nintendo family to make such statements about Japanese society when they can't even get their own company under control themselves. Nintendo is probably the most universally hated gaming company and it's true of other Japanese companies as well. They seem to be scared of the internet and goes out of their way to claim copyright infringement on anything fan made having to do with their intellectual property. They will try take down everything they possibly can, it's so bad you have to fear covering any of their games, even their music on platforms such as YouTube. Any efforts to preserve old Nintendo games via e.g. emulation is quickly met with a lawsuit. Whether or not you comply with their requests they will try to sue you for millions, even children.
