MediaWiki login translation

Hi! I noticed that you did the first translation of MediaWiki:Userlogin-signwithsecure/ja. If you test the new design on ja.wikipedia, you can see that the string as currently translated is a bit too long, and causes a line break. Do you think you could help me shorten it, or point me to another translator who can? I would be in your debt, since we're hoping to roll out the new design this week. Thanks!

Done. Thanks.

Thank you!
