I think there could be a lot more leeway in deciding cases on their own merits rather than drawing a bright line (this is an actual legal term) and decreeing that anything below the line is
BAD JUJU.
But as regards loli/shota porn, I'm saying that since the legal tolerance for IRL sexual contact with younger people has been reduced by yielding to international pressure, Japan may start performatively reducing their legal tolerance toward loli/shota hentai/toon erotica as well, meaning more censorship and sites disappearing and such. They may even make loli stuff illegal like other countries have.
