Good discussions in this thread but don't extrapolate into Japanese culture and law too much. The only source on this is from this guy's blog, summarizing what they talked about at a committee meeting. This guy is 1 of 465 members in the Japanese house of representative. He is commenting that model training is basically data analysis which is not protected by current copyright law. Note he is not a lawyer nor a powerful law maker. He also acknowledges new laws are necessary for emerging generative AI and this is basically not covered by current law. There is no news in Japan about this, because these are inconsequential discussions between members of an oversight committee handling (afaik) budgetary concerns.
