Kiramune announced that Trignal will be holding a special 2-day event in December 2023 to celebrate its 10th anniversary.
Trignal 10th Anniversary Event is going to be held at Tachikawa Stage Garden in Tokyo on December 2 and 3, 2023.
The live show takes place a couple of weeks after the release of the long-awaited mini-album set for release in November 2023.
On another note:
In 2019, Tsubasa Yonaga announced that he had been struggling with dysphonia – voice disorder / medical condition in which it becomes difficult to speak and the quality of the voice deteriorates – since late 2018 and as such, he would be reducing his activities as a voice actor.
That led Yonaga to cancel appearances for Uta no Prince Sama’s live shows and have his singing parts in IDOLiSH7 reduced to a bare minimum to avoid straining his voice. Trignal soon went on a hiatus as Yonaga focused on his recovery.
During Trignal’s hiatus, Takuya Eguchi made a solo debut in 2021 with the mini-album “EGUISM“.
5 years since the hiatus started, the group finally announced its comeback with the release of a mini-album.
