Tomorrow X Together turned up the heat a day before their Japanese comeback.

Tomorrow X Together released the music video teaser for the title song 'We'll Never Change' of their Japanese single 'CHIKAI' on their official YouTube channel at midnight on the 2nd.

The video begins with a scene where an intense light spreads from Beomgyu's eyes. Then, Huening Kai, Subin, and Taehyun stared into space as if they were missing something.

Next, a flashback scene from the time when the five members were together unfolds. The contrast between the past members who seem to be extremely happy and Yeonjun with watery eyes maximizes the affection.

‘We Will Never Change’ is a lyrical middle ballad song. The sad yet sweet voices of the five members stand out. It is expected to captivate Japanese fans.

Tomorrow X Together will release their new Japanese single 'Chikai' at 00:00 on the 3rd of next month. It contains the story of keeping the promise of 'We will be together forever' even if everything changes.

Starting with the release of the single, Tomorrow X Together will focus on their activities in Japan. On the day of release, they will appear on Fuji TV's '2024 FNS Song Festival Summer' and perform the new song.

They grace several music programs. They will appear on NTV's 'The Music Day 2024' on the 6th, TBS' 'Music Day 2024' on the 13th, and Fuji TV's 'Mezamashi Live' on the 12th of next month.

The first Japanese dome tour ‘Act: Promise in Japan’ is also coming up. They tour Tokyo Dome, Kyocera Dome Osaka, Vantelin Dome Nagoya, and Mizuho PayPay Dome.

They performed solo at the four major domes in Japan in the shortest period of time (1955 days) since their debut as Korean singers. Starting with Tokyo Dome on the 10th and 11th, a total of 8 concerts will be held in 4 cities.
