On April 5th, 2009, Alex was arrested for allegedly groping a female prep school student. 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 then was separated to become “ok rock”. The band’s name, One Ok Rock, came from “one o’clock,” the time that the band used to practice on weekends. In March 2007 Tomoya officially joined the group and the band finally made their major debut by releasing their first single 内秘心書(Naihi Shinsho) on April 25th. Because of their albums sales, their participation in relatively large festivals that summer and their energetic shows in the outskirts of Tokyo, they were noticed by a foreign record company. In 2006 they independently released 2 mini albums. After that, Taka joined as their vocalist and they focused on performing shows in the Tokyo area.

It was started by Toru with High School friends Alex and Ryota after each of them got their musical instruments. One Ok Rock is a Japanese Rock band formed in the summer of 2005.
