Language Tools now has high quality Korean and Japanese voices from Naver ! These are marked "Premium", there are 15 Korean voices (+ 2 child voices), and 3 Japanese voices. Some other generic voices are provided also.
You don't need to update Language Tools, this change was deployed on the server side. I will work on adding these voices into AwesomeTTS soon.

Naver can also translate, but it's mostly to/from Korean. Not all translation pairs are supported.
