Oishi Kenko

What Oishi Kenko does

Oishi Kenko is a Tokyo-based healthcare technology company founded in July 2016 that operates an AI-driven 'Food as Medicine' nutrition management platform across consumer, medical-institution, and enterprise segments. Its flagship is the Oishi Kenko mobile/web app, which uses data science-based nutrition, an LLM-powered recommendation engine, computer-vision meal logging, and a curated content library of 10,000+ dietitian-approved recipes spanning 80+ disease conditions to deliver personalized meal plans for chronic disease, oncology, rare disease, eating disorders, and preventive care. The company monetizes through four primary streams: (1) consumer subscription for the AI app, (2) Kakaris SaaS sold to hospitals, clinics, pharmacies, and health-insurance associations in response to Japan's 2024 reimbursement reform for lifestyle disease management DX, (3) the Patient Success Program (PSP) SaaS sold to pharmaceutical and medical-device companies for patient adherence and evidence generation, and (4) B2B healthcare marketing and professional services to food, beverage, and insurance companies via Oishi Kenko Lab. The platform is reinforced by a Real Life Data asset drawn from approximately 1.6 million monthly active users, 21+ joint clinical research studies with Japanese academic medical centers, and integrations such as Terumo's Medisafe DataShare for blood glucose synchronization. Distribution is anchored by a national partnership with pharmaceutical wholesaler Suzuken, while ownership includes strategic corporate investors Dai-ichi Life Holdings, Aflac Ventures, Toyo Seikan Group Holdings, Ajinomoto, and Suzuken.
