...which is the twitter user's reading into that line. The user acknowledged that File 4 (source of the picture) [1] doesn't mention Nightshade and that File 5 [2] contains it.

As File 5 is not searchable, I skimmed through it and found no mention of Nightshade. In fact, some points actually expressed the opposite of the twitter user's reading:

Section III 1. (1) 電子透かしが導入すべきである "[The content creator] should add digital watermarks."

The seventh point ノイズ付与の場合、電子計算機損壊等業務妨害罪になるといった可能性が指摘されているので、省庁や国としてこういった無断学習妨害ツールや電子透かし技術の正当化を担保してほしい "In the case of adding noise, someone may accuse the [creator] of the crime of business obstruction such as damaging the computer. We hope that the local and national government can ensure the legitimacy of tools for preventing unauthorized learning and watermarking."

The other points similarly stated that the content creator should watermark their works and that AI contents must embed some metadata to be identifiable as AI-made.

On top of that, these files are just minutes. Basically the Japanese government invited some companies, lawyers, and AI related associations into the Prime Minister's Office to discuss AI and IP laws, so anyone can say anything. It's not legally binding. And there are statements like we hope to use NFT as identifiers, so you can understand how serious this is.
