In 1992, Sawai Hikaru won the 14th Ministry of Cultural Affairs Performing Arts Grand Prix Award for an original work, "Shaei," for solo koto.
His concerts in 1993 and 1994 were widely acclaimed; a New Year's concert performance of "Shaei" was broadcast by satellite to all parts of the world, kindling growing interest in the koto as a modern instrument.
In 1985 he formed the rock band "Mephisto Pheles", for which he composed and played guitar.
The band had a strong following and a lasting influence, re-forming in 2001 for a 21-city Japanese tour promoting their new album “Metal on Metal” on the VAP label.
It is noted for its dynamic performances, innovative playing techniques, variety of sounds, and openness to new musical forms and combinations.
