Demae-Can and Liberta to Conduct Joint Social Experiment with 100 Delivery Personnel

Demae-Can Co., Ltd. (Headquarters: Shibuya-ku, Tokyo; President and CEO: Satoshi Yano, hereinafter "Demae-Can") and Liberta Co., Ltd. (Headquarters: Shibuya-ku, Tokyo; President: Toru Sato, hereinafter "Liberta") will conduct a joint social experiment with 100 Demae-Can delivery personnel (including 10 delivery personnel employed by affiliated stores) from July 3, 2026 (Fri) to July 31, 2026 (Fri).

In recent years, Japan has experienced record-breaking heatwaves, and heat countermeasures for those working outdoors for extended periods have become an important issue that companies and society as a whole must address. In particular, delivery personnel who support people's lives work in harsh summer heat conditions, and there is growing interest in heatstroke prevention measures and the creation of comfortable working environments.

Against this social backdrop, Liberta and Demae-Can will conduct a joint social experiment, using the summer delivery sites as a verification field, with the cooperation of 100 delivery personnel. In this social experiment, participants will wear "FREEZETECH Hyogeki α," a cooling wear brand developed by Liberta, and their comfort and fit in the summer delivery environment will be verified through actual delivery work.

FREEZETECH Hyogeki α is functional wear equipped with cooling technology that generates a cooling sensation in response to sweat and moisture, transforming sweat into coolness. Its special cooling print technology allows users to experience a cooling sensation with every sweat, supporting outdoor activities during the summer. After the experiment, a questionnaire survey will be conducted among the 100 participating delivery personnel to collect and analyze real-world feedback on their perceived comfort, satisfaction, and areas for improvement, which can only be obtained from the field.

This joint social experiment is an initiative aimed at listening to the voices of those working in extreme heat, utilizing their insights for future product development and quality improvement, and contributing to heatstroke prevention measures and the improvement of working environments for outdoor workers. Through this joint social experiment, Liberta and Demae-Can will widely disseminate the knowledge gained to society and address the social issue of heat countermeasures beyond corporate boundaries, leading to new initiatives to support outdoor workers.

Goals of the Joint Social Experiment

This joint social experiment is an initiative that aims to address challenges together with those who work in extreme heat and return their voices to society, rather than companies unilaterally disseminating product value.

The individual voices received from the 100 delivery personnel are valuable insights gained from the front lines of extreme heat. Liberta and Demae-Can will utilize these insights not only for future product development but also for creating a safer and more comfortable working environment for outdoor workers, contributing to the solution of the social issue of heatstroke prevention from a corporate perspective.
