Double is the pseudonym of the Japanese artist, Takako Hirasawa. She was born on 14 March 1975 in Niigata, Japan. When Hirasawa was a teenager, she wanted to become a hairdresser or a makeup artist. Initially, Double was a duo. The lineup included Takako and her sister Sachiko.
The young woman’s music career started when her older sister Sachiko came back from a vacation to the USA and gave Takako a tape with Mary J. Blige’s songs. The sisters were inspired by Blige’s music video to the 1992 single “Real Life”. They decided to try their luck in the music world. The sisters debuted at a concert on the US airbase in Tokyo.
In February 1998, the artists made their way into Oricon chart. The single “For Me” reached the 89th spot. The same year, Double presented three more singles, "Desire", "Shake", and "Bed". “Shake” was the most popular of them all, reaching the 21st spot on the national chart.
Before the group managed to release the debut LP, Crystal, Sachiko died from a blood disease. The album came out in the summer of 1999 and came in second on the Oricon chart. The group’s overwhelming success inspired other Japanese R&B singers, such as Kay, Ai, and Namie Amuro.
