My first guess was that the comment above ("some required packages
[don't exist]" applied.  However, it appears that you are using Ubuntu
14.04, a long-term support release IIRC, so that problem should not
exist.

This suggests that for some reason the package manager think you have
explicitly removed those "depends" packages, and don't want them.  I
can't insist on that; but the package manager's message suggests that.
Try

    sudo apt-get update

to try to get the package system itself into a consistent state,

    sudo apt-get upgrade

to try to get the installed system into a consistent state, then

    sudo apt-get check

If that doesn't complain, 

    sudo apt-get install language-pack-gnome-ja-base language-pack-ja-base

which should either work, or give you a more precise error message,
and then

    sudo apt-get install language-pack-gnome-ja language-pack-ja

If that doesn't succeed, besides any messages from the various stages,
it would help if you run

dpkg -s language-pack{-gnome,}-ja{-base,}

(the braces and commas have to be typed exactly as above -- that
notation expands to a list of all four packages that have uncertain
state).
