@LukeAlmighty @histoire you just need to keep watching, even if you feel like you don't get much.
I was able to learn English the same way, I could barely understand anything 10 years ago, but little by little I got better and never had any official training.
Shows for kids or with easygoing language, slices of life maybe.
Something you seem interested in, or even a rewatch of a show, I started with Yuru yuri and Saiki kusuo since they're my favourite shows but I can't commit rn for personal reasons.
I would recommend learning katakana and hiragana first though as otherwise you won't be able to get any of the subs.
