Tatsu was born in Saitama, Japan on September 24, 1977. His dream was to be a baseball player and he was not interested in music at all. As a matter of fact, he thought that piano-playing was for girls.

When he was 12 years old, he started to listen to pop and rock music. When he was fifteen years old, he learned to play the keyboard. He didn't like traditional teachers, so he taught himself by reading instructions. He had a dream of being a pop music star at that time, but throughout  high school, it became realistic. He gave up music for awhile to go to the National Defense Academy, much like the West Point Military Academy in New York. His father worked for the Japanese Air Self -Defense Force. Having an interest in aircraft, he decided to train to be a pilot. He passed the exams, and earned scholarships into the National Defense Academy.  After just one year, Tatsu decided to quit the academy  and focus on his music career. He played the keyboard in a pop band that played at the Gig-house  in Shibuya and Harajyuku, Tokyo. Tatsu couldn't afford to live solely on his musical wages, so he also worked  side jobs. In 2000, his band released a CD. He competed in contests and his music was promoted to the radio. April 1, 2002, his band broke up.

National Defense Academy was like hell. The world is totally different, it was like movie which shows navy seals training. After one year, he was confident and he felt like trying music again. He quit the National Defense Academy and concentrated on music life .

He was a keyboardist of a pop band, and his band used to play at Gig-house in Shibuya and Harajyuku, Tokyo. He couldn't afford to live only by music so that he had to work as temp staff. He experienced warehouse, milk delivery, English teacher, CAD designer, and so on. In 2000, his band released CD from one Indies label. He appeared on some contests and promoted their music on radios. April 1, 2002 His band broke up.

Since then, he began playing  the piano and composing his own songs. Tatsu is a composer based in Los Angeles, California. He mainly composes music for films and TV programs. In March of 2007, Tatsu landed the short film "Counting The Days" (American Film Institute, Directed by James Notari).

In November, "Always There" his  second album, was nominated for the 2007 Los Angeles Music Awards. Most of the tracks on the album "Always There," have been used for documentary programs on television. In Dec of 2007, Tatsu released 3rd album, "Motherhood". This CD includes some tracks used in films. In May of 2008, the Japan Foundation (under the Ministry of Foreign Affairs of Japan) used Tatsu's music in their PR DVD, "Forest of the Words" and "KIMONO. Tea of Silk". In July, Tatsu's music was used in a Pet Smart charities video, “Rescue Waggin,’” to help save the lives of homeless dogs and puppies.
