Koenjihyakkei is a Japanese progressive rock band from Tokyo, formed in 1991. Led by Tatsuya Yoshida, the group initially included Aki Kubota, Akio Izumi, Chie Kitahara, and Kazuyoshi Kimoto. Their debut album Hundred Sights of Koenji (1994) features non-standard modes and nonsensical lyrics. The lineup evolved with Sakamoto Kengo joining as bassist starting from the second album Viva Koenji! (1997). This period included a shift toward jazz fusion elements, notably with the addition of Komori Keiko on reeds for the album Angherr Shisspa (2005). Koenjihyakkei released the album Dhorimviskha (2018).
