ONE OK ROCK is a Japanese rock band formed in 2005 and is represented by Amuse, Inc. It performs approximately 100 live concerts every year.
In 2007, the band released its first single from A-Sketch Inc., a record label based in Japan. After the original guitarist left the group in 2009, the group became a four-member band. Since then, the band has grown at a fast pace and has performed not only at small live houses, where they initially started out, but also at numerous large concert venues. ONE OK ROCK has rapidly become one of the most popular Japanese rock bands due to its hugely successful concerts such as Nippon Budokan Live in 2010, Yokohama Stadium Live in 2014, and The Arena Tour in 2013 & 2015.
