This is somewhat a good sign, not only for South Korea, but for North America and Europe too.
Level-5 has recently used parts of the NA/EU localization of recent Yo-kai Watch games (like Yo-kai Watch 2 and Yo-kai Watch Blasters) as a base in their Korean counterparts. Assuming that this will also be true for Snack World, we could see the game in the west very soon.
I believe the anime is set to air in Italy soon, as well as America. Only a matter of time now!
