Collaboration: Tokio 4i6y11

Tokio (stylized as TOKIO) is a Japanese rock/pop band formed by Universal Music Japan from 2001 to 2008, and are now signed under J-Storm, a label owned by Johnny & Associates. In addition to their activities as a band, the of Tokio also act in dozens of dramas and host variety programmes, both as a group and individually.

Unlike most other bands under Johnny and Associates, where all of the band are usually only vocalists, Tokio only has one main vocalist, a drummer, a guitarist, a bassist, and a keyboardist. Subsequently, less choreography is used in concerts and promotional videos, and their music is often more rock-centric.

are Joushima Shigeru (城島茂), Yamaguchi Tatsuya (山口達也), Nikubun Taichi (国分太一), Matsuoka Masahiro (松岡昌宏) and Nagase Tomoya (長瀬智也). Kojima Hiromu (小島啓) was part of the band from 1990 to 1994.
