TBWA HAKUHODO Co., Ltd. (Headquarters: Minato-ku, Tokyo; President and CEO: Wataru Uchida) has won a Silver award at the world's largest advertising festival, the Cannes Lions International Festival of Creativity 2026, for 'RADIO TIME MACHINE,' a project conceptualized and developed by the company. Additionally, a pair of employees from TBWA HAKUHODO representing Japan won a Bronze award in the Media category of the Young Lions competition, an official contest for global representatives under the age of 30. Cannes Lions is one of the world’s largest international festivals for advertising and creativity. The Innovation category (Early-Stage Technology category), where 'RADIO TIME MACHINE' earned its Silver award, is one of the most challenging at Cannes Lions, rigorously evaluating not just technological novelty but also the practicality and quality of creative implementation in solving real-world societal issues. 'RADIO TIME MACHINE' is a new AI-powered device that automatically generates and delivers audio content resembling a radio program—featuring news and hit songs from a specific year—when users tune into a past year. The device combines text-generation AI and voice-generation AI in a proprietary system, developed with insights from 'reminiscence therapy,' a non-pharmacological approach that helps prevent dementia by revisiting past events. It is designed to address deep societal challenges such as elderly support in a super-aging society and fostering intergenerational communication. An observational study conducted as part of a pilot project at elderly care facilities operated by Nichii Gakkan Co., Ltd., a nationwide provider of healthcare, nursing, and childcare services, evaluated user experiences with 'RADIO TIME MACHINE.' The study compared participants' behaviors during and outside device usage through methods including facial expression analysis. Results showed an average 8.7% increase in smiling and a 10% increase in gesturing during use. The project
