Tone is the fifth Japanese studio album by South Korean pop group Tohoshinki, released on September 28, 2011, by Avex Trax. It is Tohoshinki's first Japanese album since becoming a Duo, with members Yunho and Changmin. Tone was released in three physical versions – Version A, a CD+DVD version with music videos; Version B, another CD+DVD version with off-shot movies; and Version C, a CD only version with a bonus track. Composing sessions for the album began in 2009, bull full production began in early 2011. Musically, Tone is a pop music album largely consisting of uptempos, midtempos, and ballads with R&B, electropop and rock influences. Tone received positive reviews upon its release, with some critics praising it as one of Tohoshinki's most cohesive Japanese albums to-date. The album was a major commercial success: it was Tohoshinki's second album, but first original release, to top the Oricon Albums Chart, selling 205,000 copies on its first week of release. Earning a platinum certification by the Recording Industry Association of Japan two weeks later, Tone eventually became Tohoshinki's best-selling original Japanese studio album, with over 330,000 copies sold.
