Starting in 2004, Ariyasu regularly appeared on the Fuji TV network's morning children's program "Ponkikkids", where she acted as a member of a unit called Sister Rabbits. Around the same time, she joined EXPG, the boy-band Exile's dance and vocal school for kids. The school members performed as child dancers for Exile and also received acting lessons.
On November 1, 2008, Ariyasu moved from Carotte to the Stardust Promotion talent agency, and on February 2, 2009 was put into the agency's all-girl idol group Power Age.
