TOKIO's next single "Amagasa" is a collaboration with musician Ringo Shiina. Shiina wrote and composed the song, which is scheduled for release in September.

"Amagasa" has been chosen as the theme song to the NTV drama series "Yasuko to Kenji." Premiering this Saturday, the drama stars TOKIO member Masahiro Matsuoka.

This isn't the first time that TOKIO has worked with a notable artist for their music. The group previously released songs written by Miyuki Nakajima, Yoshihiro Kai, and Tsuyoshi Nagabuchi.
