Hello.
It is me that have created the Japanese translation file, and now I am
about to solve this problem but,...
As mstssk point out, the mis-translation should be fixed, but the user
interface of Launchpad is tricky to use for me, so it may takes long
time to correct/complete all translations.
Thank you Emilio. I attach .po file on this post.
Currently, the mis-translation is fixed, but other untranslated entries
still remain because I cannot find them in the case of my using emesene.
