What they said^
I try very hard to keep the media I consume in pure Japanese (no English subtitles sort of thing) to about 80% comprehension, 70 at a stretch if I really, really want to consume that particular thing.
I mostly read, though, I don’t actually know enough Japanese for pretty much any anime to fall into that category, though looking at jpdb there appear to be a few; I also just don’t really tend to watch anime in the first place, so grain of salt.
I also don’t do the thing where I just listen to Japanese just to hear it / let it wash over me–that never did anything positive for me at all and in fact actually had some detriments I had to work extremely hard to get over–but I get that a lot of people like it so I wouldn’t recommend against it or anything.
I think, do what you enjoy, but it seems to me and many other people (such as Steve Kauffman) that 80%ish is really the sweet spot. I naturally gravitated towards that when I started reading because it felt like I was really reading, but it also felt like I was learning, but it’s also what many people recommend.
The more you do the thing (read, watch, listen–I should also mention that all the stuff I read has audio, so I read, then read and listen, then listen, only checking English if I just cannot figure out the sentence lol, and I’ve gotten MUCH better at both reading and listening doing it that way) the faster you get at doing it and the more you can handle. I stopped translating in my head about 60% of the way through N4 because of all of the reading, which I’ve heard is fairly early on, but it made listening so much easier, like holy wow, it was like I beat a much higher level boss and suddenly jumped up 15 levels at once, lol.
So I guess the tl;dr is if you can find some content that is at about 80% for you, and you don’t hate it, consuming a lot of that will be very beneficial. Stuff that’s lower is also great if you want to do it, but I think the 80% range seems to be the best balance of enjoyment and learning.
