JIS Keyboard Layout Keyboard Characters

I type on JIS keyboard layout on my Ubuntu computer.

Unfortunately xev only shows the keycode values and doesn't really help with actually changing the values. I can't seem to figure how to assign the unused keys on my JIS keyboard.

Could someone provide a similar picture or names for the JIS keys? There are 5 additional keys on JIS keyboard.
