Horikoshi High School
At the age of 15, Aragaki moved to Tokyo and enrolled in Horikoshi High School, a private high school popular for being attended by many Japanese celebrities. In 2004, she decided to put her Nicola career on hold and expand her career path into gravure and acting, and she also appeared in variety shows and commercials, with her Pocky commercials being the most popular. A year later, she officially graduated from Nicola. Even so, she still appears in the magazine occasionally.
