Huh, so that's what the Wario Roulette is based on!

It's a Japanese game like 'pin the tail on the donkey' where players put parts of a face on a template and laugh at the results.

So yeah, explains what the mini game idea came from. Now we've just got to figure out where the idea for the Wario Hop originated!

Have you tried a google image search for 福笑い ?
Most of the images that come up are kabuki masks.

Hm... looks familiar, doesn't it?

Looks familiar because the masks that the golden diva uses are called Noh masks. They are similar to a lot of Hannya or Kabuki masks that you have mentioned, but if you take a look at GD's Japanese name as Youkai(ghost or monster I guess to translate) she seemingly is meant to be a ghost. In Japanese mythology there have been spirits who would wear Noh masks too. Try pasting this to Google 能面 more Noh masks.
