Can a junior idol like Oonishi be said to have agency? She was a minor when most of her UPD8 content was produced; contracts were signed by parents or guardians, and the pressure to be "agreeable" and "genki" (cheerful) is intense. Her performances—smiling through demanding choreography, engaging with fans via comments—are forms of emotional labor. Yet to deny her any agency is also reductive. Former junior idols have spoken about genuine love for dance and performance. Oonishi’s visible skill improvement over her UPD8 tenure suggests personal investment. The tragedy is that this investment is harvested by an industry that offers fame but rarely protects the performer from later psychological or social consequences.
