As the title says: No Forum for Japanese course?
Probably because it's iOS only at this point, Give it some time
You can also use this Facebook group: Duolingo Japanese Learners
We now have a Japanese from English forum and we are now moving Japanese-related discussions over, including this one. Please post future Japanese conversations there. =]
Nope. However, someone has made a thread: https://www.duolingo.com/comment/22711921
For some of us there is no Japanese course whatsoever... but apart from complaining, I've seen a thread about Japanese which will serve as a temporary forum, you will find it under the new tab!
I really hope they will add one soon. It will be very useful. ^^
