Junk folder is the Spam folder, if you want to view the real name Spam instead of Junk:

Preferences -> Special Folders -> Activate "Show real names for special folders" -> Save

and you will see Spam instead of Junk.

If using other language, it usually will shown as Spam instead of Junk by default.
