みんなのうた
"Boku wa Kuma" was their 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.
