On September 14, 1992, Sakiko was born the oldest to a set of fraternal twins by five minutes in Kanagawa, Japan. She was born to a couple whose names remain undisclosed. Her father owns their small family business while her mother works as a middle school teacher.
Sakiko quickly gained an interest in Hello! Project after listening to Morning Musume's "LOVE Machine" with her family at a New Year's party; this lead her to audition for the group sometime in the future. After a while she immediately took up singing and dance lessons.
In early 2006, Sakiko decided to take up English lessons in order to become a bilingual speaker. Later on, at the young age of fourteen, she auditioned for Morning Musume's Happy 8ki Audition but had failed to pass the second round. However, losing the audition did not stop her from her ambitious dream to join Hello! Project someday.
In late 2012, Sakiko auditioned for LOVE Musume's first generation auditions and finally made the cut to join the group as leader; she marked this as one of her dreams come true. Overjoyed, Sakiko happily cried at once after joining Hello! Project along with the other members. Soon after, she and her family relocated to a new apartment in Tokyo.
