Yo Hitoto (一青 窈, Hitoto Yō, born September 20, 1976) is a Japanese-Taiwanese pop singer.

Yo Hitoto's mother was Japanese, and her father was a Taiwanese businessman Gan Hui Bin [zh] (顏惠民). Tae Hitoto is her older sister.

Her father died when she was very young, and her mother died when she was 16. Soon after she was born in Tokyo, Hitoto moved to Taipei, and after she completed kindergarten in Taipei, she moved back to Tokyo and she has lived there ever since. Hitoto is her mother's maiden name, which she changed to when she moved back to Japan.

She can speak four languages: Japanese, English, Mandarin, and Taiwanese.^[1]

To date, Hitoto has released eleven single CDs and four albums.

She graduated from the department of Environmental Information of Keio University and participated in the Keio University a cappella group, K.O.E., during her days as a student. She used to have live concerts on the street with fellow K.O.E. members before she met Yōichi Kitayama, a member of the famous Japanese a cappella group the Gospellers. Kitayama encouraged Hitoto to compose her own music. Before this encounter, she had been a backup singer for many other artists.^{[citation needed]}

Hitoto's debut single "Morai naki" propelled her to stardom, and her songs enjoy wide popularity. Her clear voice and singing style, which is compared to the style of folk songs of Okinawa, attract many fans. Her subsequent single Hanamizuki, released in 2004, was also a hit. The song was inspired by the events of the September 11 attacks in the United States.^[2]

In Taiwan she is known for singing a Taiwanese folk song (Bāng Chhun-hong), which was included in her second album, as part of a Kirin beer commercial aired in Taiwan.

Hitoto performed the theme song for the game Dynasty Warriors 3.

Her latest compilation album sold over 700,000 copies (Triple-Platinum status in Japan), becoming her best selling album yet.

On March 11, 2022, Hitoto participated in the Shuichi "Ponta" Murakami tribute concert "One Last Live", performing "Fever" and "Hana Mizuki". She also joined Mie in performing the Pink Lady hit single "Pepper Keibu".^[3]

In 2003 Hitoto debuted in her first film Café Lumière, as the lead character Yoko.
