How to change my keyboard settings?

Answer:
You can change keyboard layout using build-in graphical tool.
Open Main Menu --> System --> Preferences --> Hardware --> Keyboard.
Then change your present keyboard or add another, using mouse.

Alternatively, change your keyboard layout settings by running commands below:

$ setxkbmap jp

To reset to default English layout, run the command below:

$ setxkbmap us

For more information:
$ man setxkbmap
The setxkbmap command maps the keyboard to use the layout determined by
the options specified on the command line.

   An XKB keymap is constructed from a number of components which are com‐
   piled  only  as  needed.   The  source for all of the components can be
   found in /usr/share/X11/xkb.
