===== 1. Setting up Fcitx =====

Fcitx [ˈfaɪtɪks] is an input method framework with extension support. Currently it supports Linux and Unix systems like freebsd. It has three built-in Input Method Engine, Pinyin, QuWei and Table-based input methods.

Fcitx tries to provide a native feeling under all desktop as well as a light weight core. You can easily customize it to fit your requirements. 

To install it, pull up a terminal and install the japanese fcitx input module and a japanese font of your choice, i picked noto-font-cjk:

<code>
yay -S fcitx5-kkc
</code>

Configure fcitx-configtool so you can switch between your input languages (if you use dwm it will open up a text file):

In case you have dwm, you need to uncommend a specific line, it should now look something like:

<code>
[Hotkeys]
TriggerKey=CTRL_SPACE
</code>


===== 2. Locale =====

See locale for details.

Locales are used to correctly display regional or language/locale-specific standards. To ensure the Japanese locale is enabled, confirm that ja_JP.utf8 is in the output of:

<code>
$ locale -a
</code>

To enable the Japanese locale, uncomment ja_JP.utf8 in /etc/locale.gen:
<code>
/etc/locale.gen
-------------------
#ja_JP.EUC-JP EUC-JP
ja_JP.UTF-8 UTF-8
#ka_GE.UTF-8 UTF-8
</code>

Afterwards, regenerate your locale:
<code>
# locale-gen
</code>

===== 3. Input Method Framework (IMF) =====
After the installation you need to configure fcitx in your .xprofile, which means your system enviroment so that your system accepts fcitx as standard input:

<code>
export GTK_IM_MODULE=fcitx 
export QT_IM_MODULE=fcitx 
export XMODIFIERS=@im=fcitx
</code>

🎉 Finished, have fun with writing any character on earth.
