TOMORROW X TOGETHER is set to drop a new digital single in Japan this January, teaming up with a legendary Japanese rock artist.

On December 31, BigHit Music announced that TOMORROW X TOGETHER will release the digital single "SSS (Sending Secret Signals)" on January 26.

The track is a newly updated version of the song of the same name from the group's third Japanese full-length album Starkissed, now featuring HYDE of L'Arc-en-Ciel.

"SSS (Sending Secret Signals)" portrays a secret exchange of love signals hidden from the eyes of others. HYDE took part in writing and composing the song, drawing major attention when it was first revealed.

TOMORROW X TOGETHER shared the release news directly with fans during their appearance at COUNTDOWN JAPAN 25/26 on December 30, saying they hoped fans would look forward to the version featuring HYDE.

Meanwhile, TOMORROW X TOGETHER is currently on its fourth world tour, including a major five-dome tour across Japan. The group is scheduled to perform in Tokyo on January 21 and 22 as part of the ongoing tour.
