Women, South Korea
Photographing women without their consent is criminal sexual assault in South Korea. It is subject to a large fine or five years in prison. In July 2017 an amendment to the law was voted on in favour of allowing chemical castration of people taking such photographs.

Many countries have restrictions on photographing sensitive religious sites and especially dams and military installations. I got away with taking pictures of the Burning Ghats in Varanasi from a window above, and the Aswan Dam was easy but we were kicked off it after a while. I nearly got beaten up for trying to take pictures from the top of a derelict grain-silo in Zambia, the local guy I was with got a few smacks off the cop who guarded it. It must be very easy to do these shots now with phone cameras, and the tiny spy cameras you can get.
Still, it's best not to take pictures in some places, you could easily end up seriously regretting it.

I admire war-journalists, because if I see people fighting and shooting or chopping each other, the last thing I'm going to do is start getting up close taking photos of them.

I eas arrested in sudan in 1981 for photographing. Thrown in jail for two days till i was realeased.
Having been told by police in more than a few countries not to photograph. When i lived in zaire with the peace corps, my cameras were confiscatef while i was in country
