Just one quick question...
How long would you think it would take to be able to have a simple conversation in Japanese if I begin to learn Japanese with Duolingo 20 minutes a day?
Honestly, if your only learning resource for Japanese is DuoLingo, I doubt you would ever reach that level of profiency.
Unless you count a simple exchange of greetings or asking someone a basic question to be a "simple conversation".
And you can reach that level much faster using a phrase book.
DuoLingo Japanese provides a foundation, but you will need to expand your studies beyond this app to reach conversational level.
Alright, I think I'll go and look for some more Japanese learning resources, I'm also going to Japan in the summer of 2019.
Also, thanks for the advice.
i have absolutely no answers to your question, i'm just here to compliment you on that beautiful profile picture
I'd be better if you took a real fat grammar book with plenty of examples sentences along with Kaiwa ( Conversation)
I would still use duolingo but defiantly another resource, youtube has been really helpful to me Japanese pod 101 is fairly good too, to be fair although I have't been on it for years.
