In the lesson for 阪神 it says:
The slopes of the gods! What could this be? Well, it’s mainly just a company, known as Hanshin. They’re based in the area between Osaka and Kobe. Think of it this way: 大坂 + 神戸 = 阪神! They’re everywhere, though, and even have a baseball team (the Hanshin Tigers), so it’s good to know.
This threw me off when I read it, because I thought Osaka was spelled 大阪. But it looks like that’s indeed the case!
