I use a lot of your ressources aswell, but let me add some, that I found/use actively.
Kanji: Kaniwani Wanikani, but just the other way around
Vocabulary: Kitsun.io Like Anki, but on the web and nicer looking
Koohi.cafe Planning to use this a bit more, if I plan to stray from the book clubs. Has vocab lists for a lot of manga, books and anime, generated by the owner of the page. It’s a bit limited on the content, but the usability is oh so much greater!
Grammar: Tae Kim I suppose no introduction needed
I am currently mainly using Genki I paired with ToKini Andys Genki I series and a bit of Cure Dolly
General: I am starting on the book clubs right now. I have gotten myself 三ツ星カラーズ on Bookwalker and am hoping to benefit from the ABBC threads and catch up on my own time and then start with ハピネス on March 5th with the ABBC.
Listening: I really like to listen into how things are pronounced on Forvo, when I am uncertain and it is a great addition to your self-crafted Anki or Kitsun Decks! Sometimes listening to vocab makes me remember that one later on.
Elseway I tend to google a lot and read up on topics that relate to my mnenomics or are new concepts for me in Japan. Helps me a lot to get some kind of context-based mnenomic if that makes any sense? I bet there’s a word for this.
