Looks like a hot spring or bath house, but half the stools have their product sticker left on, that never appears to have gotten wet.

This is most likely a communal bath common in many asian countries. I agree on the photo op though, this looks too meticulous. And they forgot to take of the stickers of those little stools, that makes it seems even less used.

This is E. Honda's stage from Street Fighter II.

Nothing says North Korean prosperity like an unused 1975 bathhouse in 2025.
