The fact that the 65-fonts-arphic-*.conf files are present makes me think that adding fonts-takao-pgothic to:
http://bazaar.launchpad.net/~ubuntu-core-dev/ubuntu-seeds/ubuntu.xenial/view/head:/live
and
http://bazaar.launchpad.net/~ubuntu-mate-dev/ubuntu-seeds/ubuntu-mate.xenial/view/head:/live
might make a difference.
