A children's choir performs an original composition that captures the simple joy of marking time through the seasons. The song unfolds as a visual celebration of everyday moments: a child discovering the first signs of spring, summer afternoons stretching endlessly, autumn leaves collecting on sidewalks, winter snow transforming familiar streets. Each verse brings new imagery tied to how young people experience the calendar's turning, from festival preparations to school breaks to the small rituals that structure a year. The performance showcases the Tokyo Children's Chorus at work, their voices bright and earnest as they sing about the passage of time with genuine warmth. What emerges is something deceptively simple: a musical snapshot of childhood itself, the way kids notice seasonal shifts that adults often miss. The piece plays as both a song and a gentle meditation on growing up, how calendars mark not just months but meaningful changes in our surroundings and ourselves. For anyone who remembers how significant each new season felt as a child, this offers a nostalgic return to that sense of wonder.
