A brief Google search tells me that it does not. I can't seem to find anything at all that says that it does, but you're not the only one who's asked about it. I doubt it's there.
I tried to connect a microphone to my Wii and it acted like it wasn't even there so,that officially means that there is NO microphone support for Just Dance 2018,which is a shame because all Just Dance games that were released for the Wii between 2013 and 2017 had microphone support.
or game manual, if they still do thooseWouldn't make more sense to look at the menu and see if there's still a karaoke mode?
or usually the box used to have symbols with the stuff the game supported or required
If I remember correctly, jd2017 didn't have a manual, so I doubt 2018 had one either. Maybe an online one?
I had no idea any JD for Wii had any mic support. And I've used every one since 2009. There are a lot of karaoke games for the Wii, including some unofficial ones based on Sing-It Star, as well as the 5000 or songs that (were) available in the Guitar Hero and RockBand franchises.
