Originally a five piece band, guitarist Alex left the group in 2009.2005-2006: Formation and Early DaysThe foundation for One Ok Rock began when Toru Yamashita, then a high school student, wanted to start a band.
He told his friend Ryota Kohama, a fellow member of the hip hop dance group Heads, to learn the bass and asked Alex Onizawa, who was their senior in school to join.
He asked his classmate Tomo to play drums, but he left the band in 2006 to pursue an acting career.
At that time, Taka Moriuchi was playing with another band named Chivalry of Music; however, Taka didn't enjoy playing with them, so Toru insisted that he join One Ok Rock instead.
After signing with a label, Amuse, Inc.
Tomo left the band because his parents didn't want their son to walk in this way.
Tomoya Kanki actually had been teaching in ESP (Musical Academy) and have a band.
Same with Taka, that band isn't going well.
Then he has joined with them since 2006, but only became an official member when they debuted in 2007.The band's name, One Ok Rock, comes from "one o'clock", the time that the band used to practice on weekends.
However, noticing that the Japanese language made no distinction between r's and l's, they changed "o'clock" to "o'crock" (or "o'krock"), which was then separated to become "ok rock".2007-2009: Debut Album and Old FormationTheir debut single, Naihi Shinso surprisingly reached positions 48 on Oricon Chart and sold out 15,000 copies.
