This is the music documentary program "1-Re (First Reaction)" that witnesses the first moments of musicians and records their first moments. A close look at the "first time" of the active artist Takanori Iwata. Takanori Iwata will be embarking on his first solo arena tour “Takanori Iwata LIVE TOUR 2024 “ARTLESS”” starting in March. M-ON! will be covering this “first arena tour” closely! Starting from the day before the first day of the tour, the camera was focused on Takanori Iwata's front and back over two full days, and he recorded everything. In addition to an interview with the artist himself, we will also present you with valuable live footage of his "first Takanori Iwata," from entering the venue to his backstage expressions and behind the scenes.
