Toshiko Akiyoshi (秋吉敏子 or 穐吉敏子, Akiyoshi Toshiko, born 12 December 1929) is a Japanese–American jazz pianist, composer, arranger, and bandleader. Akiyoshi received fourteen Grammy Award nominations and was the first woman to win Best Arranger and Composer awards in Down Beat magazine’s annual Readers’ Poll. In 1984, she was the subject of the documentary Jazz Is My Native Language. In 1996, she published her autobiography, Life with Jazz, and in 2007 she was named an NEA Jazz Master by the U.S. National Endowment for the Arts.

Akiyoshi was born in Liaoyang, Manchuria, to Japanese colonists, the youngest of four sisters. In 1945, after World War II, Akiyoshi’s family lost their home and returned to Japan, settling in Beppu. A local record collector introduced her to jazz by playing a record of Teddy Wilson playing “Sweet Lorraine.” She immediately loved the sound and began to study jazz. In 1952, during a tour of Japan, pianist Oscar Peterson discovered her playing in a club on the Ginza. Peterson was impressed and convinced record producer Norman Granz to record her. In 1953, under Granz’s direction, she recorded her first album with Peterson’s rhythm section: Herb Ellis on guitar, Ray Brown on double bass, and J. C. Heard on drums. The album was released with the title Toshiko’s Piano in the U.S. and Amazing Toshiko Akiyoshi in Japan.

Akiyoshi studied jazz at the Berklee School of Music in Boston. In 1955, she wrote a letter to Lawrence Berk, asking him to give her a chance to study at his school. After a year of wrangling with the State Department and Japanese officials, Berk was given permission for Akiyoshi to enroll. He offered her a full scholarship, and he mailed her a plane ticket to Boston. In January 1956, she became the first Japanese student at Berklee. Soon after, she appeared as a contestant on the 18 March 1956 broadcast of the CBS television panel show What’s My Line? In 1998, she was awarded an honorary doctorate of music from Berklee, by then known as the Berklee College of Music.
