The award recognized the creation of a dynamic and consistent visual system that redefines the randoseru, a traditional Japanese school bag, as a "modern cultural product" that accompanies children's growth and exploration, embodying the brand name which means "depth" and "soar." Through these efforts, the visual expression of children's momentum to advance into the unknown world with independence was highly praised.
