I used a Ds game (yes, for real) called My Japanese coach which was a pretty good introduction to the language (game I didn't finished because of reasons), I also used some podcasts from NHK World and I've got a few japanese friends who help me with the questions that eventually arise, so far I can't just say I'm good at it but I can at the very least understand both oral and written japanese.
So yeah, just take something you like (reading, videogames, videos, audio) and search for something you can learn the language with it, as long as you keep on involving yourself with the language and
