What actually happened was that Takashi Kii of the Constitutional Democratic Party of Japan was arguing that the current laws (from 2018) are problematic because they are extremely loose and allow even illegally obtained content to be used for training, and he asked Keiko Nagao, Minister of Education, Culture, Sports, Science and Technology to confirm that this is the case. She confirmed that under current laws that's true but said that they need to keep an eye on it because there's a balance between the development of new AI technology and protection of copyright. The Ministry of Education, Culture, Sports, Science and Technology is also in the process of compiling information about case law on copyright and AI but there don't seem to be any current plans to amend the law again in either direction.
