Jin started playing music when he was 11 years old with his father's guitar. He learned classical guitar for about half a year in his town's music school. Around middle school, he started playing folk guitar and participated in band activities. He started doing live shows at places such as a park and an elementary school gym.
His band entered high school, became full-scale, went into various contests and played at live houses. At his school festival he played the guitar with 5 or 6 bands.
He studied guitar at a music vocational school and was aiming to be a professional guitar player. In the repertoire of the band that was active at that time, Jin sang in the chorus for one part of the song. He felt he was pushed by the members of his band to continue singing, and his songs inevitably increased. Eventually, he stopped playing guitar and only held one microphone.
- When he was 22, JIN joined an Earth, Wind & Fire tribute band.
- Later at the age of 34, he formed the band BETCHIN' with m.c.A.T and Hiroaki "TOMMY" Tominaga in 1998 and together they released two albums.
- He made his solo debut as a vocalist in 2000 with the song "Aozora ni Naru", the ending theme for Kamen Rider Kuuga. He performed a series of other songs on the show's soundtrack, as well as songs for the subsequent Kamen Rider Series television series Kamen Rider Agito and Kamen Rider Hibiki.
In 2015, TOMMY, Coda and JIN used the pseudonym JO☆STARS to sing JoJo Sono Chi no Kioku ~end of THE WORLD~, the second opening of JoJo's Bizarre Adventure: Stardust Crusaders and the fourth opening of the anime overall.
