Zabadak is a Japanese musical group formed by Tomohiko Kira, Yoko Ueno, and Katushi Matsuda in 1985. The sound of Zabadak has been strongly influenced by both Celtic music and progressive. In 1993, Ueno and Matsuda left and Kira continued the group as a solo act still under the name Zabadak. Kira's partner and longtime support member Koko Komine joined in March 2011. Kira died on July 3, 2016, from an undisclosed cause at the age of 56.
Zabadak was named after a song by Dave Dee, Dozy, Beaky, Mick & Tich.
The main-belt asteroid 10566 Zabadak was named after the band.
Zabadak albums include collaborations and co-writes with American songwriter Cara Jones.
