The Okinawa Actors School, which opened in Showa 58, produced artists with singing and dancing skills. In the 2000s, its activities were drastically reduced.

On the 4th, Anna Makino, who was appointed as the producer, held a press conference in Naha City. 4 members of "B.B.WAVESjr.," who were selected through auditions in April, gave a singing and dance performance. One of the members, Neil, a sixth-grader, said, "I want to make my own songs and impress the audience, so that's my goal."
