Answer by taking a quote from the following article:

Ayumi Hamasaki (Bang Qi  ayumi, Hamasaki Ayumi, born October 2, 1978) is a Japanese recording artist, record producer, actress, model, spokesperson and entrepreneur. Through her entire career, she has written all her lyrical content, produced her own music, and has sometimes co-composed her music. Born and raised in Fukuoka, Hamasaki moved to Tokyo at fourteen in 1993 to pursue a career in singing and acting. In 1998, under the tutelage of Avex CEO Max Matsuura, Hamasaki released her debut single "Poker Face" and debut major-label album A Song for XX.

Born in Fukuoka Prefecture, Hamasaki was raised as an only child by her mother and grandmother. Her father had left the family when she was three and never again came into contact with her. Hamasaki's mother worked to support the family, so Hamasaki was primarily taken care of by her grandmother. She described herself as a "tomboy" when she was a teenager, and as a "strange kid" who "liked to be alone". At age seven, Hamasaki began modeling for local institutions, such as banks, in order to supplement the family's income. She continued this career path by leaving her family at fourteen and moving to Tokyo as a model under SOS, a talent agency. Her modeling career did not last long; SOS eventually deemed her too short for a model and transferred her to Sun Music, a musicians' agency. Under the name of "Ayumi", Hamasaki released a rap EP, Nothing from Nothing, on the Nippon Columbia label in 1995. She was dismissed from the label when the album failed to chart on the Oricon. After this failure, Hamasaki took up acting and starred in B-movies such as Ladys Ladys!! Socho Saigo no Hi and television dramas such as Miseinen, which were poorly received by the public. From August 1995 to March 1996, Hamasaki also co-hosted the SoundLink "magazine" Hokago no Osama (After-school King) for the Nintendo Satellaview once a week with Shigeru Izumiya. Growing dissatisfied with her job, Hamasaki quit acting and moved in with her mother, who had recently moved to Tokyo. Hamasaki was initially a good student, earning good grades in junior high school. Eventually, she lost faith in the curriculum, thinking that the subjects taught were of no use to her. Her grades worsened as she refused to put her mind to her studies. While living in Tokyo, she attempted to further her studies at Horikoshi Gakuen, a high school for the arts, but dropped out in the first year. Hamasaki did not attend school or have a job, so she spent much of her time shopping at Shibuya boutiques and dancing at Velfarre, an Avex-owned disco club. At Velfarre, she was introduced to her future producer, Max Matsuura, through a friend. After hearing Hamasaki sing karaoke, Matsuura offered her a recording deal, but Hamasaki suspected ulterior motives and turned the offer down. He persisted and succeeded in recruiting her for the Avex label in the following year. Hamasaki started vocal training, but skipped most of her classes after finding her instructors to be too rigid and the classes dull. When she confessed this to Matsuura, he sent her to New York to train her vocals under another method. During her foreign sojourn, Hamasaki frequently corresponded with Matsuura and impressed him with her style of writing. On her return to Japan, he suggested that she try writing her own lyrics.
