Because it's a large country, as in 126M people, where a lot of them have internet, and a lot work in the creative business, so it's influence on worldwide media and internet is relatively large. What we as non japanese get to see of the japanese erotic stuff, is mostly the weird things. That's already filtered out for us. We have more than enough home made "normal" erotic stuff so we only want to see foreign things if it's different. Hence we get to see the weird fetishes.

Another factor is very strict censorship. Particular body parts need to be pixels since the late 80's. So they shift focus to other bodyparts, that can be considerd weird fetishes.

I'm not from Japan or the US, and the countries best known for weird and extreme porn are:

1. United States
2. Germany
3. Japan

Much more than half of the extreme porn is from the US. Germany adds a lot of unsafe sex and things normally reserved for the bathroom. Japan adds some elaborate weird things.

I don't see any relation with censorship or being reserved. The US is very conservative and puritan, high censorship with normal nudity, but little censorship with 18+ stuff. Germany is much less puritan and has no censorship with nudity. And Japan is very conservative, has little censorship with normal nudity but high censorship with 18+ stuff. I don't see a pattern. Except for bigger country -> more weird porn stuff on the internet.
