あと10ぷんでねるじかん (JP Oversized)

The mix of animals and imagination creates such a whimsical world—I'm curious what inspired that choice and how it enhances the bedtime feel.

The 10-minute countdown made the story feel interactive, but I wonder if that was intentional to help kids transition to sleep more smoothly.

The artwork is so lively and charming—I'd love to know if the illustrations were planned first or developed alongside the text.
