This is because Japanese is written in more than one script.  So to do
"Japanese" you need to use all of them, but you need the other stuff
to be correctly handled so that conflicting variants don't arise.

Those of you who are not familiar with the VIP and root LGR projects
might want to read that material, which I think is linked (it used to
be anyway) from the UA pages.
