Change your netflix app language to your target language and you magically get more subtitle options, if available. In US Netflix, when I set my language to english, I see english, spanish, and maybe french or italian for some shows. When I set my language to Korean, I see English, Korean, Japanese, and Chinese (trad and simplified) when they are available for that show.

Why they base it on your display language and don't just have a setting that is "show me X, Y, and Z language subtitles if available", I don't know.
