-> start learning Grammar to understand sentence structure / start reading easy japanese / start listening to easy japanese / start practicing speaking simple japanese / partially work through a core anki deck to get introduced to a bunch of common kanji quickly but be wary of treating anki reps as anywhere near as important as media consumption.
Look up stuff you don’t understand in dictionairies/jisho/grammar guides/ web.
-> keep reading/listening/speaking & mine your own Anki deck based on the stuff you come across adding in the word and the sentence/context you came across it in.
Repeat until fluent.
Add on whatever methods help you get over personal obstacles you come across, like mnemonics if it helps remembering specific kanji you have trouble with. Don’t worry about those until you actually start having those troubles.
