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?
That’s a quite standard time line to properly learn a language. Also depends what you mean by “pick it up”: getting a soda at the supermarket? Probably a week. Reading their maximum works of literature? Much longer. Having a reasonably smooth conversation and being able to read some small books? 3 years and about right
