www.lentil.com

They have both Japanese and Korean, although the Japanese section is a lot more than the Korean section of the site.

The site mainly just gives the very basic for learning. I pretty much only use it for learning hiragana and katakana, but it also has some kanji too.

I hope this helps :)

For vocabulary: www.memrise.com

For grammar: www.imabi.net and www.guidetojapanese.org/

For conversation hopefully: www.italki.com ;)

Ich hoffe ich konnte behilflich sein. 

Danke :D
