WD_Hiroshi [1] filed a deletion request for mozc-with-jp-dict [2]: This package is probably not meant for Arch Linux. It doesn't build on an Arch Linux as you can see in the comments of multiple persons. The files in the AUR-git-repo are strange with routines not required to build. The packages on GitHub are build on Manjaro. The maintainer does not really react to the comments and doesn't reply to mails.
