Since I am constantly talking about it with some IRL friends, they at least know that "there is a touhou". But when I suggested the danmaku games to one of them, he gave it a try. He didn't hate it but he wasn't interested in playing more. But he knows some characters and memes. Recently though, I met someone who had heard of the series. Other than that, touhou is *extremely* niche in my country so I don't expect anyone really to have even heard about it.
