>can I use this to get a job or something
Yes and no, most companies don't need people who speak Japanese, so you probably won't have any luck there, though it might help you during the job interview slightly.
You can move to Japan and work some minimum wage jobs, or after some training(assuming you're native English speaker) become English teacher in Japan(I'm not that familiar with the process, so I can't tell you the details).
>or turn my life around
Probably, not. If you don't wanna be a neet, get a job, any job really, or go get some education. Anything's better than nothing.
