Update: April 28th, 12:38 PM PT — Details surrounding the concert’s uncertain future have been clarified in this article.

The Tokyo Mirage Sessions #FE Encore Premium Live music concert, which was originally scheduled to take place on June 27th at the Tokyo Dome City Hall, received an update on its official site today to announce that the event has been canceled at this time.
As with many other public gatherings worldwide, such as the recently canceled Fire Emblem Expo II, the concert was held off as a countermeasure against the coronavirus pandemic in order to prioritize the safety of all involved.
