Matenrou Opera lit. 'Skyscraper Opera' is a Japanese Visual kei rock band. The band was formed in 2007 by Sono and Yuu who were previously the vocalist and drummer of Jeniva.[1] Their first maxi-single was on the OFFICE A to Z label.[1] "Alkaloid Showcase" was released on May 4, the same day as their first concert, but the single sold out before the concert began.
In late 2007, keyboardist Karen and guitarist Mika left the band and were replaced by Ayame (ex-Ry:dia) and Anzi respectively.

In 2008, after joining the label Sherow Artist Society, the single "Ruri Iro de Egaku Niji" hit number 11 on the Oricon Indies Chart; the EP Gilia hit number 7 and was also released in Europe.[2][3] Matenrou Opera toured through Europe with Versailles from the end of March to the beginning of April 2008.

In late 2009, Matenrou Opera shared a national tour of Japan with Deluhi.
