Mr.Children - “Tabidachi no Uta”

A new Mr.Children song, Tabidachi no Uta, has been confirmed as the theme song for the film Koizora. It is currently not confirmed as a single but it is speculated that IF it is released as a single (which is highly likely), it may possibly be out around the time of the film, which would be November 2, a day before the film’s release.
Koizora was originally a digital novel and was released in book form late last year. It proved to be highly popular so a film adaptation is not unexpected. Natsuki Imai, who was responsible for dramas such as Orange Days and Taiyou no Uta, will be directing this film. Filming on the film begins at the end of July and will be released around November.
