When she started modelling in 2006 at age 14, Shinozaki caused widespread press and web comments about her having an unusually curvy figure for a Japanese teenager.

In July 2006, when Shinozaki was in her third year of middle school, she debuted as a leading idol at Chu → Boh, a gravure magazine specializing in female junior idols in middle school aimed towards male readers, published by Haewangsa.
