The Theory of HappinessNEW!Shiina Ringo
This is a commercial depicted in a gentle, animated style, featuring a girl who has just entered elementary school and her parents.
The parents are earnestly taking pictures of their daughter wearing her randoseru backpack, while the girl being photographed looks a bit overwhelmed.
However, the line that appears near the end of the commercial—“You’ll grow up so fast”—conveys the parents’ feeling that they want to capture as many moments as possible right now.
The background music uses a cover of ‘Koufukuron’ (A Theory of Happiness), which is familiar from this series of commercials.
Sung in a child’s voice, the song has a different charm from the original performed by Sheena Ringo.

It highlights that the foam comes out ready-made, making it easy for little kids to use.
The BGM features “Gips,” one of Ringo Sheena’s signature songs.
Although it’s originally a love song, when paired with this footage, it feels like it’s singing about the love between parent and child.
