&TEAM Surprise-Releases Japanese Version of "Good Boy" After Tokyo Debut

&TEAM has surprise-released a Japanese version of "Good Boy" following the song's first performance in Tokyo.

The nine-member group released "Good Boy (Japanese ver.)" across digital platforms at midnight on September 22. The original track appears on &TEAM's second Korean mini album Mark on Me.

Just hours before the digital release, &TEAM debuted the Japanese version live during a Mark on Me showcase at Tokyo Garden Theater on September 21.

Built around a dynamic 808-driven beat, "Good Boy" places particular emphasis on performance. Member K participated in creating the choreography, which brings &TEAM together with a group of dancers to unfold a larger story across the stage.

The members described "Good Boy" as a track that allows them to show a performance that feels "even more like &TEAM," pointing to the combination of powerful rap sections and a more melodic pre-chorus.

The Japanese release follows a new sales high for Mark on Me. The mini album surpassed 1.35 million copies in first-week sales on Hanteo Chart, setting a new personal record for the group and becoming &TEAM's fourth consecutive million-selling release.

&TEAM will conclude its current Asia tour with two concerts at KSPO Dome in Seoul on October 3 and 4.

The group will then launch the 2026-2027 &TEAM CONCERT TOUR ‘Mark on You' at Tokyo Garden Theater on October 15. The tour is scheduled to span 41 performances across 18 Japanese cities.

&TEAM said the upcoming tour will give them an opportunity to personally thank LUNÉ in areas they have not previously been able to visit.
