I remember that when I was living in Tokyo, in a tall building (I think one of the tallest residential building in Tokyo, in Shiodome, 54 floors, but I was "only" at the 22th floor), there used to be airships/zeppelins flying between the buildings once in a while. Very uncommon sighting for me. This was years ago, decades even and I don't know if they're still to be seen in Tokyo or not. I think they were some kind of touristic attraction but I'm not sure.
