A birthday song that feels like someone remembering you exist. Seiichi Hayashi's animation moves with the gentleness of the melody, no rush, no drama, just a moment held still. The kind of thing you come back to when you need to remember what warmth sounds like.

Otanjoubi Omedetou is a one-episode music video made for a song by Megumi Shiina. The song was featured on Minna no Uta, a program on the Japanese broadcaster NHK. The animation for the video is the work of Seiichi Hayashi.
