What Okeios does

Okeios Co., Ltd. (株式会社オケイオス) is a Japan-based health-technology company headquartered in Fukuoka that operates a blockchain-secured information distribution platform built around a Personal Data Store (PDS) architecture. The platform allows individuals to register and manage their own health data — examination records, medical history, lifestyle logs — and to share that data on consent-based terms with municipalities, medical institutions, insurers, research institutions, and corporate health programs. Blockchain is used not for raw data storage but for storing digital certificates derived from source health data, providing authenticity, confidentiality, traceability, and identity verification. OKEIOS is an equity-method affiliate of CMIC Holdings via CMIC Solutions (since September 2022) and re-booted as the operating entity in April 2026 following a business succession of the healthcare business from CMIC Trust.

The product surface is a platform-plus-modules architecture: the core information distribution platform is delivered through consumer apps (Mirai Health Handbook, an all-in-one health management app co-developed with Hiroshima University and the Kanshin COI; Mother-Child Health Management), enterprise modules for medical institutions and municipalities (DocTip, aSBoEMR combining PHR and EMR, municipal data health planning support), the aSBo Cloud System blockchain clinical trial information platform deployed with Irom Group, and a Risk Prediction AI for preventive health guidance. Two granted patents anchor the technology: the BCN Data Utilization System and the AI Event Class Determination System. The technology stack integrates Google Fit for wearable data ingestion and exposes SDK and API access for third-party health apps, insurance systems, and municipal platforms to participate in the consent-managed data exchange.

Commercially, OKEIOS earns revenue through platform licensing and PDS management subscriptions to municipalities and medical institutions, SDK/API licensing and transaction-style fees on data exchange, custom application development and integration services, and quotation-based enterprise contracts rather than published pricing. Go-to-market combines direct enterprise sales to Japanese local governments and medical institutions with channel partnerships through CMIC Group (pharmaceutical and clinical trial reach), Irom Group (clinical trial site network), and academic co-development with Hiroshima University, Kurume University, Keio University, and Fukuoka University. Government-level validation comes from METI Information Processing Support Institution certification (2019), METI cross-industry collaboration certification (2020), listing in the Digital Agency's Digital Garden City Nation service catalog (2023), and the 2024 Japan Patent Attorneys Association IP Utilization Award Grand Prize.

Scale indicators4 records

Recent moves8 records

Expansion highlights5 records

Broad incumbents

• Philips HealthSuite: Enterprise-scale cloud platform for connected health devices, patient data, and clinical workflows with consent and identity management. Comparable enterprise/governance positioning and a benchmark for what scaled health data infrastructure looks like.
• M3 Inc. Japanese digital healthcare platform operating MR-kun, MDLinx, and clinician networks with growing consumer health data assets. Relevant as a broad incumbent competing for healthcare data exchange, clinical trial, and consumer PHR segments.
• NTT Data Japan: Major Japanese IT services provider with broad healthcare offerings including EMR, regional healthcare networks, and government health information systems. Okeios already partners with NTT DoCoMo in Hiroshima Sandbox, and NTT Data represents the type of large incumbent Okeios must displace in municipal procurement.
• Apple Health Records: Apple's patient-mediated health records service aggregating EMR data from participating hospitals on consumer iPhones. Comparable patient-mediated data access model and represents the de facto global PHR incumbent Okeios must interoperate with.

Regional players

• LINE Healthcare: LY Corporation's healthcare subsidiary offering online consultation, health management apps, and PHR services on the LINE platform in Japan. Comparable in targeting Japanese consumers and municipalities for health data and wellness programs.
• DeNA Healthcare: Japanese internet company's healthcare division operating consumer health apps and healthcare data services. Comparable Japan-domestic PHR/data positioning and an obvious competitor in municipal and corporate health programs.

Direct peers

• Patientory: Blockchain-based healthcare information exchange and PHR platform enabling secure patient-mediated data sharing between individuals, providers, and payers. Directly comparable product positioning and underlying blockchain-for-health-data thesis.
• Welby: Japan's leading PHR platform company, providing disease-management and health-data apps used by patients, providers, insurers, and pharmaceutical companies. Most direct Japanese PHR competitor to Okeios's Mirai Health Handbook and municipal PHR offerings.
• Solve.Care: Blockchain healthcare platform coordinating patients, providers, and payers with consent-based data exchange and care administration. Comparable in offering decentralized data sovereignty and cross-stakeholder information distribution.
• BurstIQ: US-based platform using blockchain and distributed ledger technology for secure health data exchange, consent management, and PDS-style individual data sovereignty. Closest functional analog to Okeios's blockchain + PDS architecture in the global market.
