One ok rock is a Japanese Band that was formed on 2005. The foundation for One Ok Rock began when Toru Yamashita, then a high school student, wanted to start a band. Toru told his friend Ryota Kohama, who had been a fellow member of hip hop dance group, HEADS, to learn the Bass and asked Alex (a former member) to join. After seeing Taka, a vocalist, perform in a cover band, Toru saw him as the best possible candidate for a vocalist in their band, and insisted that he join. They released their first Indies CD in 2006 and got signed by Amuse, Inc. whom they made their major debut with. Tomoya, the last member to join, joined One Ok Rock as a drummer in 2007. Tomoya had played with band on all their albums but only became an official member when they debuted.

The band name, One Ok Rock, came 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 then was separated to become "ok rock".

Alex left the band after charged for a criminal act. After, ONE OK ROCK released "Kanzen Kankaku Dreamer" single on Feb 3th 2010, placed 9th in Oricon Chart.
