Level-5 has released a version 2.1.2 update for Yo-Kai Watch 4 in Japan.
The update changes the Yo-Kai Watch 4 icon on the Home Menu to the icon for Yo-Kai Watch 4++. However, please keep in mind you’ll still have to purchase the Yo-Kai Watch 4++ DLC in order to access content exclusive to Yo-Kai Watch 4++. Other than this major change, several bug fixes were made.
