"Boku wa Kuma" was Utada's first try at writing a children's song.

On October 1, 2006, it aired on the children's music program Minna no Uta on radio, and on TV the day after.

Due to strong demand, the song had been planned for continuous rebroadcasting from October 2006 to January 2007 on Minna no Uta.

[1] "Boku wa Kuma" was Utada's first single release to have three different pressings: a limited edition that included a picture book, a standard single and cover, and a CD+DVD combo pack, which included the music video.

The song was performed during Utada's two date concert series Wild Life in December 2010.
