I know its easy to do props but it really looks like a hospital, the beds and the TVs and even an MRI machine. I know they did use a real airport for some scenes in the airport batsu, I was wondering if the hospital is real [possibly a disused hospital]?
The filming locations are often schools and I think that’s the case for the hospital. It’s been a while since I’ve watched it but it’s neither an active hospital nor a disused building.
They use schools since they have set closed days and the designs are plain making them easier to convert. They’re also large buildings with simple layouts and a lot of big rooms.
They take field trips to other locations relevant to the theme.
