Ningen Isu

Ningen Isu is a Japanese heavy metal band formed in 1987 in Aomori Prefecture. The group consists of Shinji Wajima, Kenichi Suzuki, and Nobu Nakajima, and their sound is rooted in metal, rock, and doom metal. Known for heavy riffs, strong bass work, and a dark melodic edge, Ningen Isu often draw on Japanese literature, folklore, and horror imagery in their lyrics. That mix gives the band a distinctive identity within Japan’s rock and metal scene, where they have built a long-running catalog marked by consistency, musicianship, and a theatrical sensibility. The band has released music through Tokuma Japan Communications Co., Ltd., and their official website is ningen-isu.com.
