Nav Katze (ナーヴ・カッツェ) is a female music duo from Tokyo, Japan consisting of Naoko Iimura (飯村直子) (guitar) and Miwako Yamaguchi (山口美和子) (vocal and bass). The band was formed in 1984 with a third member, Shino Furutachi (古舘詩乃) (drums). After having released two records on the SWITCH label, they made their major debut on Victor Music Industries (Victor Entertainment) with the album Kanki. Shino Furutachi left the band in 1991 after this album. Later, they collaborated with famous rock band LUNA SEA.
Due to the obscurity of the group there is very limited information relating to them and their activities. Nonetheless several of their songs have been remixed by well-known artists, such as Aphex Twin, Black Dog Productions, Autechre, and Global Communication.
