Members: Yasufumi Yamashita, Rikiya Yamashita, Eijiro Shimada, Yoichi Shimada

Sorma formed in 1995 and has rotating a membership that focuses on
No.1 (Yoichi Shimada)
and three other performers:
No.2 (Eijiro Shimada)
No.3 (Yasufumi Yamashita)
No.7 (Rikiya Yamashita)
Each performer is given a number, perhaps to lend an air of mystery or anonymity which holds a certain cachet in some dance circles. However, each performer is also clearly listed by name and number in the liner notes.
No.V-1 (Kazuhisa Nakagawa)
No.V-2 (Masahiko Kumai)
No.P-3 (Makoto Yanagisawa)
No.D-1 (Gunther Haller)
Sormanager: Keiko Takayanagi
