"64 - Rokuyon" is based on the police detective novel by Yokoyama Hideo about an unsolved kidnap and murder of a young girl in the last year of the Showa era i.e. Showa 64th year thus giving it the nickname of Rokuyon. 14 years later, another kidnap case arises which brings back memories of the Rokuyon that was regarded as a blemish in the police's history. The two-part movie features Sato Koichi as the lead character Mikami who used to be part of the investigation of the Rokuyon and is now a public relations officer. He commented that when he read the original novel, he already realised that it would be a tough job to act in this movie so he was mentally prepared for the challenge. As for the theme song, Sato commented that when Oda sings the theme song at the end of the movie, it gives the peaceful feeling that a long battle has finally ended and things have settled down. The director Zeze Takahisa also stressed that Oda's song is especially fitting as a sign of hope for people who still miss the days of the Showa era and lament the feeling of loss due to the end of that period in their lives.
