Copying commits from PR #8006 (Phrase)

[internetisaiah]

Summary

Copying commits over from #8006 without the commit history due to issues with cla-bot. I did this by:

git checkout develop && git pull
git checkout -b i18n_phrase-ja-isaiah-1318
git checkout i18n_phrase-ja _lang/ja/*
git commit -am "TITLE"
git push -u origin i18n_phrase-ja-isaiah-1318
