Nav Katze were a female Japanese rock group. Initially a trio, drummer Shino Furutachi left Nav Katze in 1991, thus leaving the
lineup to be a duo. Originally, Nav Katze had a more gloomy feel, which came across like a gothic post-punk mixture. Although
after Furutachi's departure, Nav Katze began to delve more into the fields of electronica and avant-garde. Nav Katze appeared
to have disappeared by the new millennium.
