Die Eröffnung ist verschoben worden. Die Googleübersetzung eines Auszugs aus dem aktuellen Newsletter:
Universal Studios Japan has carefully examined the current situation from various aspects when issuing the "State of Emergency" to Osaka Prefecture on January 13, 2021, and as a result, it was scheduled for February 4th. The opening of the area "Super Nintendo World" will be postponed after the "state of emergency" is lifted.
We sincerely apologize to all the guests who are looking forward to the opening of "Super Nintendo World" for their concern. The opening date will be announced again after the "emergency declaration" is lifted.
