Once, as members of the same group, they helped define an era: Sato Hiroyuki and Yamamoto Junichi, who have spent years building careers in their respective fields, will reunite on the Billboard Live stage. Continuing to expand their horizons in stage, music, and expression, the two present a special concert titled "Thanks," conveying their gratitude to those who have supported them through music. In addition, as a special guest, Koji Utsumi, who likewise helped shape an era as a member of the same group, will appear. The stage where the times and experiences they have walked overlap is sure to be a memorable moment for not only fans who knew those days but for all audiences who encounter them today.
