I currently have to use Subtitles, kinda annoying. And I despise dubs since the voice acting is so bad, I mean like the emotions in the voice, its so emotionless in English.
I am a English speaker with some fluency in Cantonese and Mandarin.
How difficult is Japanese? Am I gonna waste a lot of time?
Also what’s the best resource to learn?
I think you mean Wago and Kango counting, in which case Kango isn’t irregular at all. There are sound changes, but they almost all follow a handful of basic rules. Wago is plenty irregular, but it also stops at ten and is only used for a handful of things. It’s messed up, sure, but not the end of the world.
The calendar? Their months are literally just firstmonth, secondmonth, thirdmonth, etc.
