Apparently, there is a protest against a regulation which Japan put on the porn industry on how long a studio has to wait before a film (with an actual actress) is published (over a month). It is said to be driving a black market, of interfering with people's livelihoods, and of being an undue burden on businesses (it is even said to violate Article 22 of the Constitution).

It appears it is going to be reviewed soon, and a member of the House of Councilors (the upper house) is already strongly critical of it. I remember an article from some time ago where people from, I think, the Constitutionalist Democratic Party mocked it.
