In August 2011, she replaced the graduated Saki Ogawa of S/mileage on the children's morning program Oha Suta as an Oha Girl. On March 27, 2012, Ikuta and Oha Girl Maple have graduated from the show.  On March 27, 2012, she graduated from Oha Star and Oha Girl Maple.

Morning Musume member color
First, Erina Ikuta was assigned the color purple. In July 2012, it was changed to yellow-green, the color of Risa Niigaki, who had graduated from Morning Musume on May 18. Erina very much wanted Risa's color, so her official color was changed to yellow-green.
