TL;DR
A new children’s umbrella called Kage no Otomodachi, developed by Torinoko and All Stadium, uses shadow play to motivate kids to use it for sun protection. The umbrella creates playful figures on the ground that children can follow, turning shade into a game. The project aims to improve outdoor sun safety among children through behavioral design.
A Japanese-designed children’s umbrella, Kage no Otomodachi, creates playful shadow characters on the ground to encourage kids to use it for sun protection. The project aims to make sun safety engaging for children by turning shade-seeking into a playful activity, according to the designers.
The umbrella, developed by Torinoko in collaboration with All Stadium, features illustrated companions that appear as shadow figures when opened in direct sunlight. Children are encouraged to follow and walk alongside these characters while remaining beneath the umbrella’s canopy, transforming the act of seeking shade into an interactive game.
Designed in response to rising concerns about children’s exposure to extreme heat, the umbrella aims to address the challenge of convincing children to use parasols. It leverages children’s natural fascination with shadows, embedding playful figures within the shaded area cast by the umbrella. The design is based on behavioral principles that promote voluntary protective behaviors without framing them as rules or obligations.
The product is currently available in a turquoise-blue color on the Japanese crowdfunding platform Makuake, with plans to introduce additional colors and refinements. The project also emphasizes increasing cultural acceptance of parasol use among children for outdoor safety.
Implications for Child Sun Safety and Behavioral Design
This project demonstrates how playful design can encourage children to adopt protective behaviors voluntarily, potentially reducing risks associated with heat exposure. By integrating entertainment with safety, the umbrella could influence broader cultural attitudes toward outdoor sun protection and inspire similar innovations.

Rising Concerns Over Children’s Heat Exposure and Shade Use
With increasingly intense summer temperatures, children are at higher risk of heat-related health issues, partly because their thermoregulation systems are still developing. School commutes and outdoor activities have become more challenging, prompting designers and health advocates to seek engaging solutions to promote sun safety. Parasols are effective but often underused by children; thus, innovative approaches like the Kage no Otomodachi aim to address this gap.
The concept emerged from a collaboration initiated at the Tokyo Metropolitan Government’s Design Management School, focusing on reducing risks faced by children in everyday outdoor environments. The umbrella is a part of ongoing efforts to integrate behavioral insights into product design for health and safety.
“The design leverages children’s natural fascination with shadows to create an engaging way to stay protected from the sun.”

Unclear Aspects of Long-Term Adoption and Effectiveness
It is not yet confirmed how widely children will adopt the umbrella or whether the shadow play will significantly increase parasol use over time. The long-term impact on sun safety behaviors remains to be studied, and future research is needed to evaluate effectiveness.
Next Steps for Broader Implementation and Impact Evaluation
The project is currently in early deployment via crowdfunding, with future plans to expand color options and refine the design. Researchers and designers may conduct studies to assess how effectively the umbrella encourages consistent use and whether it influences outdoor safety habits among children.
