Description of problem: Please see /usr/share/locale/ja/LC_MESSAGES/fedora-release-notes*.desktop. no Name[ja] entry there. Version-Release number of selected component (if applicable): fedora-release-notes-15.1.0-1.fc16.noarch
I can see "Name[ja_JP]=リリースノート" in modern package. I'm not sure it actually works, since every other .desktop file uses "ja" code.
