Learning Japanese

I want to learn japanese in order to play untranslated visual novels. My question is if pimsleur is a good idea for me or not? It seems to be primarily focused upon audio, I am not sure if this will be a waste or essential in developing an understanding of japanese. I would like to learn japanese as fast as possible and this is my first time learning a new language so I am very lost. Thank you in advance.

If it is your first time learning a language, you're not learning it in an immersion environment or classroom, and you plan to focus on listening comprehension, you might be better off quitting before you start. Japanese is not a piss in the breeze, and some parts are harder for self-study than others. If you want to test yourself to see just how hard it's going to be, go to erin.ne.jp/en/ and feel out the skits.
