<aside> Japan’s elder-care system has a measurable attention deficit. Persimmon Quest addresses this through non-diagnostic, AI-assisted cognitive engagement, brain-health monitoring, staff workflow support, and longitudinal care-context infrastructure.

Persimmon Quest is building a non-diagnostic AI-assisted brain-health and elder-care attention infrastructure for Japanese long-term-care facilities. The platform combines resident-facing cognitive engagement, session-based brain-health data capture, staff workflow support, and longitudinal care-context generation through the qBand Controller, qPad Oasis, and qCore Pillar ecosystem.
The first deployment wedge is Oita Prefecture, where a smaller and aging regional care market allows pilot validation. Aichi Prefecture provides the second-stage scale-validation market, with a larger institutional care base and stronger industrial ecosystem. Japan represents the lead national market, with expansion potential across ASEAN and East Asia as regional elderly-care demand rises toward 2030.
Persimmon Quest’s first market is the institutional elder-care attention layer in Japan. Oita alone contains roughly 171 core long-term-care institutions and about 9.2k institutional residents, while Aichi contains roughly 512 core institutions and 42.2k residents.
Nationally, Japan has about 13.6k core long-term-care institutions and 933k institutional residents, within a broader base of 7.08M certified support/care-need persons and more than 36M people aged 65+. By 2030, Japan’s 75+ population reaches roughly 22.5M–22.8M, while ASEAN’s 60+ population exceeds 100M and East/Northeast Asia’s older population exceeds 300M.
This creates a clear wedge: prove AI-assisted attention, cognitive engagement, and longitudinal brain-health monitoring in Japanese facilities, then scale into certified-care and preventive-care markets across Asia.
The analysis estimates Persimmon Quest’s opportunity through four layers: institutional facility TAM, certified care-need TAM, AI-assistable attention demand, and token/infrastructure demand. This approach connects demographic aging to real facility deployment, product usage, qCore compute requirements, and projected economic impact.
We split the assistive geriatric care market into four layers:
| TAM layer | What it means | Best metric |
|---|---|---|
| Institutional deployment TAM | Nursing homes, care homes, geriatric facilities, dementia group homes, senior residences | facilities, beds, residents |
| Certified care-needs TAM | Elderly people already certified for support / long-term care | Government’s LTCI (要支援・要介護) certified persons |
| Preventive brain-health TAM | 75+ or 60+/65+ people at rising risk, before severe care dependency | elderly population, especially 75+ |
| Regional expansion TAM | ASEAN / East Asia elderly-care demand by 2030 | 60+ population and estimated LTC need |
For Persimmon Quest, the most investable wedge is not “all elderly people.” It is:
AI-assisted attention and cognitive-care infrastructure for formal elder-care facilities, starting with high-need residents, then expanding into preventive monitoring and home/community care.
The market should be measured across four layers: core long-term-care facilities, certified care-need populations, high-risk preventive-care populations, and regional Asian expansion markets. For Japan, the most reliable market base is the Long-Term Care Insurance system, which provides official data on insured elderly persons, certified care-need persons, facility-service recipients, and institutional care facilities.

The "insurance calculation" refers to a specific metric called the Standardized Care Time (要介護認定等基準時間). This is an estimate of how many minutes of care per day a person requires, calculated by a computer algorithm based on a 74-question survey of their daily activities. The insurance level is determined by this standard. This is not the actual time a helper visits, but a statistical estimate of the "burden of care" required for 5 categories of tasks:

Japan’s official care-need categories presented in range:
| Japanese category | Meaning for PQ |
|---|---|
| 要支援1–2 | light support / preventive care |
| 要介護1 | early formal care need |
| 要介護2–3 | medium care need |
| 要介護4–5 | high care need / strongest institutional attention need |
Persimmon Quest works in the 3rd to 5th range of government insured care time, and models care demand as AI-assistable attention rather than simply counting elderly people or care taker deficits. Residents and care recipients are grouped into light, medium, and high attention needs based on Japanese long-term-care certification levels.
Japan’s Long-Term Care Insurance system was established in 2000 to support elderly care socially; people aged 65+ are primary insured persons, and people aged 40–64 are secondary insured persons eligible under specified diseases. MHLW states the system supports about 6.9 million service users. (Ministry of Health, Labour and Welfare)
Oita is treated as pilot market. Aichi is treated as the scale-validation market. Japan is treated as the national proof market for Persimmon Quest. ASEAN and East Asia are treated as 2030 expansion markets to take our service further to create global value.
