From what I've read, and don't quote me on this, but Japan is apparently PROUD of how they've upheld the law. It might also have to do with how the porn business there works; due to the nudity laws, they focus on more niche fetish stuff and make money off that.
Why would they be proud of a law that the US instituted during WWII?
Japan literally has shrines dedicated to genitals.
Isn't there also some genital parade in Japan?
Any material that might negatively affect the 'natural' feeling of shame that is linked to anything sexual is banned by law.
In practice, they have for some reason decided to just blur or cover with black bars or make a 'proud sword' a proud swor and call it good after that. It's more a practice than a law.
I think it's some vague "obscenity" law that has come to be defined as "literally anything goes just as long as you blur out the genitals".
Fun fact: child porn was legal in Japan until 1999, when it was made illegal due to pressure from the US.

What is a "proud sword"?
