## Background and release

"Chiisana Koi no Uta" is the third track of the Okinawan band's second album Message which was released on September 16, 2001. The album became the first indie album to reach 1 million sales on Oricon.
Music duo Fuki and Tee, describe the song's genre to be "rock", while Kyu Nakanashi describes it as J-pop. The lyrics of the songs were written bassist and vocalist Kiyosaku Uezo while the other band members composed the music. The main key is B major, the time signature is $^4$ $_4$, and the tempo is 116 Bpm (232 Bpm in double time). Gordon Maeda, who played the role of Shinji Fukumura in the movie, said that the simple and repeating chord progression makes "Chiisana Koi no Uta" easy to learn.
In an interview with Rina Sako from Natalie in 2019, Uezo said that he did not know the song's key when he was writing the song commenting that "Chiisana Koi no Uta" starts in a lower key but with a higher chorus. He also said that he did not use the personal pronouns Boku (僕, lit. I) and Kimi (君, lit. You) while writing the song's lyrics as residents of Okinawa do not to use personal language when speaking, adding that at that time he thought that Anata (あなた, lit. You) was more fitting. Music critic Shiba Tomonori stated that the song uses the adjective "Chiisana" (小さな, lit. 'Little') because it "focuses on the relationship with 'you'", rather than bigger things such as wars, nations and the environment.
According to Hasumi Aku from Utaten, the song is about the love between a boy and a girl who have grown up together on a small island until the girl has to leave the island. The song is written from the boy's point of view and shows that his feelings for her will never change. In a 2019 interview, Gordon Maeda said that he initially thought of "Chiisana Koi no Uta" as a love song but after reading and studying the lyrics for his role he realized that the song expresses the feelings of the band towards Okinawa.
