A single song becomes a whole world. Keiji Kawahashi's composition doesn't just play over animation, it builds the room you're sitting in, the air you're breathing, the quiet that makes you stop scrolling and actually listen. This is what happens when a children's program trusts music enough to let it lead, and animation follows like it's answering a question the song already asked.

Yamaguchi Sanchi no Tsutomu-kun is a single-episode animated music video set to a song by Keiji Kawahashi. The song was featured on NHK's Minna no Uta program, and this short piece provides the animation that goes with it.
