SHELLMET, an environmentally friendly helmet made from discarded scallop shells, designed by TBWA\HAKUHODO in partnership with Koushi Chemical Industry Co. and quantum inc., was selected from “Co-Design Challenge Program” by Japan Association for the 2025 World Exposition. As a result of this selection, Shellmet will be the official disaster prevention helmet for the World Exposition 2025.

“Co-Design Challenge” is a special co-creation project to call for sponsorship of facilities, goods and services necessary for the site operation in order to make the Expo even more attractive and to create a comfortable site for all visitors. The concept of the “Co-Design Challenge” is to make the Expo “an opportunity to build the future of lifestyle in Japan.”

SHELLMET, an eco-friendly product that aims to contribute to the achievement of the Sustainable Development Goals, matches the concept of the Co-Design Challenge program and was selected from among 79 applications to the program. The design and specification of SHELLMET will be updated specifically for the Expo, to be used as the official disaster prevention helmet of the Expo.
