How will tourism in unified Korea change?

Question

Currently, South Korea is so active in tourism that about 18 million tourists visit annually. If North and South Korea were to unify, what tourist attractions would receive attention? And how much would the number of tourists increase?

The first place that comes to mind after unification would definitely be Pyongyang. Also, the wildlife in the Demilitarized Zone (DMZ) could become a new tourist resource. I am curious about the long-term direction of tourism development in North Korea. Especially, I have many questions about how the major cities and natural landscapes of North Korea could be utilized.

What do you think the tourism industry in unified Korea will look like? I am particularly curious about your opinions on the tourism development potential in North Korea.
