FA5 is a Japanese visual kei rock band, formed in 1999. The band currently consists of five members: vocalist Naoto Inti Raymi, guitarist Ryōta Kusakabe, drummer Yūya Fujita, bassist Takayuki Matsumura and support keyboardist Tomoaki Watanabe.
The band's music style is mainly rooted in hard rock and metal, with occasional forays into other genres such as electronic music and pop. Their lyrics often deal with dark or personal themes such as mental illness, suicide and death.
FA5 released their debut album Fade in 2002, followed by Nostalgia in 2004 and Dystopia in 2006. They have since released three more albums: New Beginning (2009), Requiem (2011) and Chaos Theory (2013). The band has also held several tours both inside and outside of Japan.
In 2014, FA5 announced that they would be going on an indefinite hiatus due to creative differences between the members. However, they reunited in 2016 and have since been actively touring and releasing new music.
