Number Girl (ナンバーガール, Nanbā Gāru) was a rock band formed in Fukuoka, Japan in August, 1995 by guitarist and vocalist Shutoku Mukai. They disbanded in 2002 following bassist Kentarō Nakao's departure from the band.Number Girl played fast, guitar-driven rock similar to the Pixies, Sonic Youth, and Hüsker Dü. Over the course of seven years their sound evolved greatly, serving as a basis for Mukai's post-Number Girl project, Zazen Boys.
