Started with friends introducing me to anime in highschool (with english subtitles), which I got hooked on, then got into the music as well, and later into vtubers (so no subtitles when watching live). I haven't ever really been into other entertainment, so for a little over a decade I've been listening to japanese on a near daily basis.

I know it's a meme for people to claim to know japanese from watching anime, which is why I don't claim to be able to speak it, but over time I did pick up enough that I don't need subtitles anymore. I'm slowly working on reading with practice books, wanikani etc, will eventually figure out some way to practice speaking too.
