<aside> <img src="/icons/brain_red.svg" alt="/icons/brain_red.svg" width="40px" /> Japan’s elderly care market is entering a new era — one where brain data, personalized care, and AI-enhanced hardware converge. Every aging brain carries a lifetime of signals we barely understand. Persimmon Quest builds the precision intelligence layer to understand every brain at their individual levels.

In Beppu, Japan, I lived inside a tragic inefficiency. On two sides of the street there were two small elderly care homes. Wondering what they do there, I started volunteering, and some of the residents said to have children who are above 50 years old. I could clearly see a super-aging population fading in silence behind the "8050" walls.
So, Initially I wanted to create a video chat application that creates realtime subtitle with DeepGram. But with AI smart captioning newly released on the market, it was a very expensive Web3 project to maintain. So I had to think of cost-effectiveness, and that’s when I needed to think at a more deep science level to solve much bigger but specific pain points.
We don't have a resource shortage; we have a connection failure. Japan has cold sensors to watch the elderly; PQ makes them warm with AI to engage their aging brain better.
Yunomi is not just any chat app. It is a data-driven social ecosystem that can convert Student Curiosity into Social Infrastructure. We are taking the "burden" of care and turning it into a "quest" for a far more global understanding.
We succeed in our lab. Then we take it to nursing homes. Then we bring it to the whole world as a longevity tech stack.
**We start as a non-profit lab. We prove our AI enhanced neural activity data means something in Japan’s rural areas with our trust-first, move-fast work ethic.
We then commercially bring this aging brain research through multi-device ecosystem to the rest of the world to understand their brains better without getting a haircut or a surgery.**
