From a fascinating NHK World (from Japan) documentary about their super toilets:
And then there was the hotel room I had in Singapore the same summer, the toilet was in the room, and the only concession to privacy was… a roller blind hung from the ceiling which you pulled down in front of you once you’d sat down 
. Luckily I was travelling alone, it was a double room and I can only imagine one person would go out for a walk while the other took care of business.
