The title, "Tsubame", was revealed on September 28. Ayase explained about the song, "I wanted to make a song that brightens the message of what we can do about the perspective of swallows flying in the sky, the activities and problems of the people we can see from there, just by listening to it." The group formed by NHK, called Midories, was also announced on the same day, consists of five elementary school students from the first to the fifth grades—Atsuki, Ukyou, Lexie, Ririna, and Yumeri—to feature vocals of the song with Yoasobi.

## Lyrics and composition

"Tsubame" was written by Ayase, a member, and producer of Yoasobi, and recorded by the vocals of the duo Ikura, featuring the vocals of Midories. It was composed in the key of B♭ major, 105 beats per minute with a running time of three minutes and 37 seconds. Lyrically, like the based story Chiisana Tsubame no Ōkina Yume, "Tsubame" tells from the perspective of a swallow as a protagonist, shows the tragedy of the sea it went through, positive and negative aspects and behavior of humans towards nature, sympathy for others, and ends up with a scene where swallows bring happiness to people. The song incorporates the idea that even small swallows can achieve big things if they cooperate together, which leads to the efforts of SDGs.
