so apparently cure dolly prosyletizes an organic immersion process to learn. she suggests using anime with japanese subtitles, going through line by line, looking up words and reasoning out the meaning of each sentance, helped by having gone through a fair amount of the structure lessons. then after finishing an episode, ripping the audio and putting it on your life's full time background sound track playlist. as you finish more episodes that playlist of anime audio grows. importantly it's anime you already worked through so you should have an understanding of it, even if you don't understand it fully on listen. This is quite different from AJATT which claims you just need to fully immerse without any understanding until your brain learns to decode (after heisig etc)

anyway. there are some good guides for making the process pretty seamless. key apps/extentions: Anki, Yomitan, absplayer
https://learnjapanese.moe/routine/ (day 6 for anime with subtitle setup)
decent site for streaming : https://animelon.com
kitsunekko.net for offline subs of many shows, but i suggest Xavier's Retimed JP Sub Pack - https://nya.iss.one/view/1044354 first since downloading everything all at once is easier (had to rename a bunch of the srt/ass files to match my already dowloaded stuff :/ )
also https://gist.github.com/tatsumoto-ren/78ba4e5b7c53c7ed2c987015fa05cc2b is a good hub for offline subtitle sources.

absplayer lets you use yomitan on your local media, since it wouldn't work in mpv or vlc.

learnjapanese.moe also has a VN guide to make yomitan useful, but i haven't read into it yet.

https://syosetu.com is the obvious choice for reading materials.
anyway.
