TBWA\Hakuhodo Launches AI-Powered ‘Radio Time Machine’ to Spark Memory + Joy in Elderly Care
TBWA\Hakuhodo has unveiled the ‘RADIO TIME MACHINE’ project, featuring a pioneering AI-powered device designed to automatically generate era-specific radio-like audio content historical news and popular music. This innovative project, initially implemented in collaboration with Nichii Gakkan, a leading care facility operator in Japan, aims to stimulate memories, cognition and communication, while enhancing the well-being of residents in elderly care settings.
TBWA\Hakuhodo saw AI and digital devices as more than tools for convenience—they could also enrich human experiences and relationships. Applying its “Human Innovation” philosophy, the agency focused on Japan’s aging society, where challenges such as cognitive decline and gaps in intergenerational understanding are growing.
A key concept in the project was Reminiscence Therapy, a non-pharmacological approach that uses familiar stimuli—like old photos or music—to support cognitive and emotional well-being and help prevent dementia. Inspired by this idea, TBWA\Hakuhodo developed “RADIO TIME MACHINE,” a system that uses generative AI to recreate audio experiences reminiscent of past radio programs. By evoking nostalgic memories, the project aims to bring joy to the elderly while fostering dialogue and connection between generations.
The device features an intuitive design reminiscent of a 1950s-60s radio, complete with a classic radio dial. Users can select a desired year, instead of frequencies, by turning the dial, operating the pointer in one-year increments from 1950 to 2025. Once the pointer aligns with the chosen year, the AI instantly generates a unique radio broadcast that plays content “from” the very date you are playing the radio, but from the year selected.

The generated content seamlessly blends news headlines from that era, selected based on a curated topics list, with period-appropriate hit songs. An AI-generated voice, based on human voice recordings ranging in age and gender, acts as the radio personality. The voice delivers the content in a style designed to evoke a sense of the period selected, while immersing listeners in the memories of their chosen era. The system is engineered to ensure a varied and engaging experience as users explore different historical periods. The playback duration of the audio content can be freely controlled by AI, ranging from several-minute loops to several hours depending on the purpose.
A pilot project to introduce the ‘RADIO TIME MACHINE’ into Nichii Gakkan’s care facilities has yielded promising results.
The initiative focused on two key objectives: enhancing resident wellbeing and improving communication between residents and staff. Feedback from the pilot program highlighted several positive impacts:
· With RADIO TIME MACHINE, residents were able to recall details of their past, such as their parents’ and former employers’ names, which they previously struggled to remember due to dementia-like symptoms. Speaking to residents as they listened to news and songs from the past, the staff noted increased memory recollection and quicker responses to questions from residents.
· By comparing users’ behavior with and without the RADIO TIME MACHINE—using facial expression analysis, activity-level analysis through skeletal pose estimation, and speech-rate measurements—three key findings emerged.
1. Facial expression analysis showed that reminiscing the past increased the smile index (which detects the mouth-corner angle and cheek elevation), by an average of 8.7%. In some cases, listening to the radio increased this value by 23.8%, indicating a notable rise in smiling.
2. Activity-level analysis through skeletal pose estimation showed a 10% increase in gestures and hand movements. This is most likely due to higher motivation to explain the content of their memories to others.
3. Speech-rate measurements showed an increase of 10.8 words per minute. It is speculated that a variety of memories were evoked by listening to the radio, motivating users to share with others.
These observations underscore the device’s potential to re-engage residents with their minds and personal histories, fostering emotional uplift and more vibrant social interactions within the care environment.
In this documentary of the pilot project, we see care facility residents interacting with RADIO TIME MACHINE in real life, recalling memories from long ago and brimming with smiles TBWA\Hakuhodo has also initiated joint research with Kitasato University (Tokyo, Japan) to further validate the device’s impact. The project aims to scientifically measure the benefits of RADIO TIME MACHINE on cognitive functions and emotional health. For instance, Behavioral and Psychological Symptoms of Dementia (BPSD), include restlessness, irritability, and decreased motivation. The joint research will validate how RADIO TIME MACHINE can reduce these symptoms through quantitative assessments, as well as behavioral analysis and facial expression analysis.
Nichii Gakkan will plan for wider implementation of RADIO TIME MACHINE based on these research results, including the development of an affordable version utilizing smartphones, along with deployment in facilities across the nation.
Beyond their initial collaboration with Nichii Gakkan, TBWA\Hakuhodo is exploring new projects utilizing RADIO TIME MACHINE. The creative collective believes this AI device has potential across various fields—not only in eldercare and welfare, but also in music, entertainment, and many other domains. They also see strong potential for product development, including new hardware designs and more affordable models. For further information or partnership inquiries, contact the following.
Kenshiro Suzuki, Creative Director at Innovation Hub, TBWA\Hakuhodo, said: “The concept of RADIO TIME MACHINE came up in a team meeting, discussing new ways to solve challenges within our rapidly aging society. Over two and a half years, we refined multiple mockups, software, and hardware designs. This year, we have been able to introduce RADIO TIME MACHINE as a pilot to some care facility residents. Through interacting with RADIO TIME MACHINE, many residents suddenly remembered long forgotten memories, while others talked in detail about their childhood neighborhoods. All this by hearing news and music from 70 years ago.
“I cannot forget their smiles I saw. I hope that RADIO TIME MACHINE will soon be introduced into care facilities across the country, helping the elderly reminisce together, stimulate one another, and enjoy their daily lives even more.”
