Onmyo-za (Japanese: 陰陽座, Hepburn: Onmyō-za, literally "gathering of yin and yang") are a Japanese heavy metal from Osaka, who released their first album in 1999.
They play quite orthodox heavy metal music, mixed with elements from Japanese folk and pop music, and play both fast, hard songs and slow ballads. Since their debut in 1999, they have appeared in traditional clothing characteristic of Japan's Heian period.
Their name refers to Onmyōdō and the gathering of yin and yang (Inyo in Japanese, formerly Onmyō), and the theme of opposites and cosmic dual forces are prevalent in their lyrics. This contrast is also represented by the female and male vocals and two guitarists.
Each of the band member's stage names feature a double entendre with a sense of humor and make references to cats.
It's a gloomy day
Sun hides behind grey cloud
Depression and hate
Now inside of me
Dies irae - earth starts to shake
Dies irae - there's no escape
Dies irae - against me you can't provide
Dies irae - god must die
Dies irae - earth starts to shake
Dies irae - the time of change
Dies irae - against me you can't provide
Dies irae - christ must die
Wrath is the source
Of each emotion (of mine)
Dies irae - earth starts to shake
Dies irae - there's no escape
Dies irae - against me you can't provide
Dies irae - god must die
Dies irae - earth starts to shake
Dies irae - the time of change
Dies irae - against me you can't provide
