Japan is intensifying efforts to use technology to address a worsening dementia crisis, as more than 18,000 older people went missing last year and care-related costs continue to climb.

With nearly 30% of its population now aged 65 or older, Japan is experimenting with GPS wearables and community alert systems that help authorities locate missing individuals within hours. AI tools are also entering clinical practice, including Fujitsu’s aiGait system, which analyses posture and movement to detect early cognitive decline.

Researchers at Waseda University are developing AIREC, a humanoid robot that can perform basic daily-living tasks and may one day assist with continence care and pressure-ulcer prevention.

Smaller social robots such as Sharp’s Poketomo aim to reduce loneliness by prompting medications, offering weather updates and providing companionship. Despite this technological push, caregivers and researchers stress that human connection remains fundamental.

Community initiatives such as Tokyo’s Restaurant of Mistaken Orders show how social engagement can support dignity and wellbeing even as automation and AI begin to supplement routine care tasks.
