Shuuma began his career in 1998 at Kamata's Studio 80 as a DJ primarily selecting UK and NY hard house, focusing his activities mainly in Tokyo before ceasing activity in 2004. Unable to forget the outdoor party Rainbow 2000 he attended as a high school student, he was fortunate to meet the members of OtOdashi, which became the turning point for his return to activity. In the early days of his involvement with OtOdashi, he mainly selected progressive house to play in the early morning. However, with time, while retaining some of those elements, he was influenced by his peers and incorporated elements of techno and deep house, establishing his current style. Currently, he has returned to Breakbeats, pioneering a path to fuse it with the styles he has cultivated so far.
