Bullet Train to release fan-collaboration track ‘Gachi Muchu!’

The Japanese musical group Bullet Train (Chotokkyu) has announced the digital release of ‘Gachi Muchu! (feat. 8-go-sha)’, scheduled for September 19, 2026, at 13:00. This marks the group’s first collaboration track specifically credited with their fan base, known as ‘8-go-sha’.

The track features live audio recorded during the ‘BULLET TRAIN ARENA TOUR 2026 ESCORT’ at K Arena Yokohama on August 8, which coincides with ‘8-go-sha Day’. To ensure a complete recording, vocals from member Ryoga, who was on a hiatus during that specific performance, were mixed in from a different concert.

The release aims to capture the intense energy and calls from the fans, symbolizing the bond between the members and their supporters as the group celebrates its 15th anniversary and prepares for upcoming performances at the Tokyo Dome.
