BE:FIRST — Where to Listen on the Radio

Be:First (stylized in all caps) is a Japanese boy band formed and managed by BMSG and signed to B-ME, a joint record label with Avex. The group was formed on November 3, 2021, through the reality competition show The First, which is hosted by Sky-Hi and debuted on August 31, 2022 with heir studio album Be:1. The group consists of six members: Sota, Shunto, Manato, Ryuhei, Junon, and Leo; Ryoki left the band in 2025.

The group is BMSG's first act. Sky-Hi created the company after identifying issues in the Japanese music industry, including a lack of opportunities for talent to showcase themselves, which led talented performers to leave Japan for the wider opportunities offered by the Korean music industry.
