Japanese input in Linux environment (fcitx-mozc)

[Priv.-Doz. Dr. M. Shinoto]

Hi,

I have been using a Mac over decades, but now I am preparing for a 
change to Linux, testing all software and setups on an old Lenovo 
Thinkpad with LinuxMint 18.1.

Emacs does not accept the Japanese input with fcitx-mozc, and there are 
some forum posts from which I could only learn that "it sucks". I did 
not found anything helpful.

Can anybody give me a hint into the right direction, how I could use 
Emacs with Linux and Japanese?

Thanks,
Maria
