What >>49695004 said. If you don't mind torrenting, I recommend the Touhou Project All-In-One Pack on nyaa. There should be a readme that explains how to use the language patcher, but it's all pretty straightforward. Don't feel like you need to play every single game in chronological order. There's not really an overarching plot and official Touhou games are pretty light on story. I also recommend starting with 6. It's a very good game and all of the characters have gone on to become fan favorites.
