> Interesting, I didn't know that they drank much black tea in Japan.

Actually, there are many teahouses in Japan that don't even carry
Japanese green tea. They wouldn't serve much of it, since it is
regarded as the tea "people have at home". Many Japanese like to go out
and they like to try something less ordinary.
Darjeeling teas seem to be popular because the name is familiar and
famous, but many people actually don't like it when they try it. It is
usually too week and most prefer the stronger blacks from Ceylon or
Assam...
