A children's song that sounds like it was composed in a dream, where a character steps softly through illustrated worlds and everything moves at the speed of wonder. Yumi Ishikawa's voice carries the kind of gentle certainty that makes you believe in the person singing, not just the song. This is what happens when a broadcaster decides to make something for the part of you that still needs to be told that magic is real.

Fantajii-san no Uta is a single-episode music video for a song performed by Yumi Ishikawa together with the Morinoki Children's Choir, and it aired on NHK's Minna no Uta program. The video centers on Fantajii-san, a character created by Tsuneji Tsukagoshi, a former NHK announcer who also wrote the song's lyrics. His younger brother, Teiji Tsukagoshi, provided the illustrations that make up the video.
