What BrainCare does

BrainCare Inc. (ブレインケア株式会社) is a Tokyo-based, privately held Japanese IT company founded on January 4, 2016, that develops AI-based products and services for the early detection and prevention of dementia. The company is led by Representative Director Daisuke Yamamoto and operates with a 1–10 person team across a headquarters in Setagaya, Tokyo, and a recently opened Nagano Office in Ueda City. Its core product is the Ninkatsu Dojo (認活道場) dementia prevention program, launched in October 2016, which is designed around the epidemiological premise that delaying dementia onset by five years could reduce dementia incidence by roughly 50%.

The company's technology stack combines an AI-based simple intelligence assessment scale (developed June 2019), a cognitive function training API and content library, IoT-based elderly monitoring services, and dementia prevention food products formulated from Hisayama Town, Fukuoka Prefecture epidemiological research (conducted since 1961). BrainCare maintains a database of dementia-related data gathered from its own prevention programs and IoT services, with the stated intent of supporting medical research and treatment development. Partnerships span research (Waseda Elder Health Business Division, Capital Medica Group), technology/social isolation (OQTA), and large enterprise distribution (Ajinomoto Co. for API licensing since May 2021; NTT docomo for content distribution to docomo shops since April 2021).

BrainCare's business model combines several revenue streams: subscription/recurring revenue from the Ninkatsu Dojo prevention program, API and content licensing royalties to enterprise partners, food product sales, and data monetization through medical data analysis services. Its go-to-market is API-first and enterprise-field-sales oriented, distributing cognitive training content and assessment capabilities through large corporate partners rather than direct-to-consumer channels. The company is pre-IPO, founder-owned, and has raised only one disclosed funding round ($91,369 from Capital Medica Ventures in June 2017), indicating operations have been largely self-funded. Recent activity has pivoted toward an agricultural-welfare initiative in Nagano Prefecture, including grape cultivation since May 2024 and a regional office opened in April 2025.
