Sheena worked together with producer and guitarist
Yukio Nagoshi on the song, as well as "Irohanihoheto". Sheena had previously worked with Nagoshi during her
Ringo Expo concerts in 2008, and on the songs "Zero Chiten Kara," "Togatta Teguchi" and "Yokyō" on her solo album
Sanmon Gossip (2009). Her previous
Tokyo Jihen bandmate
Ichiyo Izawa played the
harpsichord on "Irohanihoheto." Bassist Hitoshi Watanabe had previously worked with Sheena as a member of
Bōtoku Vitamin, one of the bands who performed on her album
Utaite Myōri: Sono Ichi (2002). Drummer Noriyasu Kawamura previously worked with Sheena on her debut album
Muzai Moratorium (1999). "Kodoku no Akatsuki" is a song featuring lyrics written by screenwriter Aya Watanabe, who wrote the screenplay for the
NHK morning drama
Carnation. This is the first time Sheena did not write the lyrics to a promoted single track. The pair had worked together on
Carnation, as Sheena had written the
eponymous theme song, but had never met face to face before. After being asked to write a theme song for an NHK show called
Switch Interview: Tatsujintachi, Sheena was inspired by the concept of the program, in which a team of interviewers ask and debate topics. She wanted to express this teamwork nature in the song, so asked Watanabe to write the lyrics. She came up with the melody for the song after hearing her son and her elementary school age niece singing the children's song "
Kaijū no Ballad." == Promotion and release ==
