Uno was born into a wealthy family. Her father was a copywriter and her mother was a social worker. Inspired by London's West End's Cats, Uno, from a young age, had aspirations of becoming a stage artist.^[8]

Her childhood was difficult and unsure; she described her primary school years as "dark times", as she was not good at running and jumping. Afflicted with a frail body and slow reflexes, she determined while still young to make herself regain confidence.^[8]

She spent fifteen years at Shirayuri Gakuen (白百合学園). At the age of 8, she began to write essays and study dance at this school. At the age of 11, she and two other students left Japan, representing the Ministry of Education, to go Germany's International Summer Camp.^[8]

She could not speak with other students because she didn't know any German. She decided to study English hard and resolved on going abroad. She later studied in London during her grade 8 summer vacation.^[8]

During her first year of high school Uno auditioned in Avex Group's "Avex Audition 2002,” where she came in second out of tens of thousands of participants. She was then signed onto the Avex Artist Academy. A year later, she set up the dance club of Shirayuri Gakuen. This club is the predecessor of AAA.

She made her debut in the 2005 drama SLOW DANCE, though it was only as background music. Later that year, she appeared as Mai Honda in the art film Their Waters (彼らの海) VIII -Sentimental Journey-. She had her first starring role as Akane Sueyoshi (末吉茜) in the 2006 antiwar drama Bokura no te (ボクラノテ).

In the same year, Columbia Pictures held an audition in search of an actor to be signed under their company. She passed the audition and made her Hollywood debut in the 2006 horror film The Grudge 2, as the Japanese student Miyuki Nazawa.

She had her first starring film role as Taniyama Miguru (谷山めぐる) in the 2010 Japan comedy film rendez-vous (ランデブー!). At the end of the year, she first appeared on NHK’s Kōhaku Uta Gassen.

In 2011, her early experiences were included in the Stepping stone Vol.7 Misako Uno, an English textbook compiled by the MEXT middle school and high school.^[9]

Keiichiro Koyama of NEWS announced his marriage to Uno on March 12, 2024. They registered their marriage on March 12, which is also the birthday of Uno's beloved father, who passed away in January 2023.^[10]
