TL;DR
A new children’s umbrella called Kage no Otomodachi uses playful shadow characters to encourage kids to seek shade and protect themselves from the sun. Developed by Japanese designers, it turns sun protection into an engaging activity. The project aims to improve outdoor safety during hot summers.
A Japanese-designed children’s umbrella, Kage no Otomodachi, now features playful shadow characters that encourage children to seek shade and protect themselves from the sun through interactive play. Developed by torinoko and All Stadium, the umbrella aims to make sun safety appealing to children by transforming the act of seeking shade into a fun activity, addressing the challenge of encouraging consistent use of parasols during hot weather.
The umbrella, created in response to rising summer temperatures and concerns about children’s heat exposure, reveals illustrated companions within its shadow when opened in direct sunlight. These playful figures, cast onto the ground, invite children to follow, chase, and walk alongside them, naturally keeping beneath the umbrella’s canopy. The design leverages children’s fascination with shadows, transforming a protective behavior into an engaging experience.
Developed through a collaboration at the Tokyo Metropolitan Government’s Design Management School, the project is currently available on the Japanese crowdfunding platform Makuake. It features a turquoise-blue color, chosen for visibility and recognition outdoors. Future versions may include additional colors and refinements, aiming to promote broader acceptance of parasol use among children. The umbrella also includes reflective details to enhance visibility during rainy or evening walks.
Innovative Approach to Children’s Sun Safety
This development matters because it addresses a persistent challenge: convincing children to use sun protection regularly. By embedding playful, curiosity-driven elements into protective gear, the umbrella encourages voluntary use, potentially reducing heat-related health risks for children. It also reflects a broader trend of designing safety products that align with children’s natural behaviors and interests, making safety routines more engaging and less burdensome for parents.

Rising Summer Temperatures and Child Safety Concerns
As summer temperatures become increasingly extreme, concerns about children’s exposure to heat have grown. Children are more vulnerable to heat due to their proximity to hot surfaces and developing thermoregulation systems. Traditional parasols are effective but often underused by children, who may find them boring or inconvenient. The design of Kage no Otomodachi responds to these issues by integrating playful shadows with behavioral design principles, aiming to turn sun protection into an activity children want to do.
“The idea is to shift from forcing protective behaviors to creating conditions that children want to participate in voluntarily.”
