Zabadak (ザバダック, Zabadakku) is a Japanese musical group formed by Tomohiko Kira, Yoko Ueno, and Katushi Matsuda in 1985. In 1993, Ueno and Matsuda left and Kira continued the group as a solo act still under the name Zabadak. The sound of Zabadak has been strongly influenced by both Celtic music and progressive.
Zabadak was named after a song by Dave Dee, Dozy, Beaky, Mick & Tich. The main-belt asteroid 10566 Zabadak was named after the band.
The character Sakuya Kira from Kaori Yuki's "Angel Sanctuary" was named after Tomohiko Kira, but since Yuki couldn't take Tomohiko as a first name for her character, she took "Sakuya" from Konohanasakuya-hime.http://www.angelicvoice.fr/index.php?id=y-1995
