What Medical Data Vision does

Medical Data Vision Co., Ltd. (MDV) operates Japan's largest medical administrative database, covering 62.42 million actual patients in its Hospital Database and 21.02 million in its Health Insurance Database, sourced from 871 of Japan's 1,761 DPC-designated hospitals (~49% of advanced treatment facilities). The company ingests and processes more than one million health claims per month and updates its datasets monthly with data from roughly two months prior, spanning inpatient, outpatient, electronic receipt, and clinical examination data since April 2008. MDV's data asset underpins 822 peer-reviewed publications and is licensed to over 100 organizations including pharmaceutical companies, medical device manufacturers, academic institutions, and health insurers.

MDV monetizes the database through three revenue streams: (1) Medical Database Services, sold as annual subscriptions to MDV analyzer, MDV analyzer for Oncology, and MDV analyzer for Clinical Insight, plus ad hoc analysis and dataset extraction; (2) Hospital Software Solutions, including MDV Act, MDV Act Link, EVE, Medical Code, KanGoch+ (Kango-ch+), and ALPHA/SALUS, sold as embedded applications to DPC hospitals; and (3) Ad Hoc Analysis Services, priced on a custom, quote-based basis. Pricing is not publicly disclosed; free trials are available for the analyzer family. Go-to-market is direct enterprise sales via Tokyo and Kyushu offices.

The company was founded in August 2003 and previously traded on the Tokyo Stock Exchange (TYO: 3902). In early 2026 Nippon Life Insurance Company completed a 52% majority acquisition for ¥40.4 billion (~$380M), making MDV a wholly-owned subsidiary and reorienting it as the data backbone for Nippon Life's healthcare and digital health strategy. MDV maintains ISMS JQA certification and operates exclusively in Japan; international expansion has not been signaled in available materials.

Scale indicators6 records

Recent moves6 records

Expansion highlights5 records

Direct peers

• JMDC (Japan Medical Data Center): JMDC is the most direct Japanese comparable: it builds and monetizes large-scale health insurance claims and medical checkup databases in Japan, selling RWD analytics to pharma, insurers, and academia using a subscription model similar to MDV's MDV analyzer offerings.
• Health Catalyst: Health Catalyst provides enterprise data and analytics platforms to hospitals and health systems for operational and clinical improvement—mirroring MDV's hospital-side software stack (MDV Act, EVE, Medical Code) while also serving analytics use cases.
• Definitive Healthcare: Definitive Healthcare aggregates provider, claims, and commercial intelligence data sold to medtech and pharma for go-to-market and market research—an adjacent but comparable healthcare-data-analytics subscription business model targeting similar enterprise buyers as MDV.
• Flatiron Health (Roche): Flatiron is the benchmark specialty RWD platform (oncology-focused) used by pharma for real-world oncology evidence and clinical decision support; MDV's MDV analyzer for Oncology is a direct functional analog for Japan-based oncology RWE work.
• Evidera (Thermo Fisher / PPD): Evidera monetizes real-world evidence, health economics, and outcomes research for pharma clients using curated datasets—closely comparable to MDV's MDV analyzer for Clinical Insight and ad hoc analysis services used in post-marketing and HEOR studies.

Emerging players

• Komodo Health: Komodo Health builds a software-and-data RWD platform (Healthcare Map) serving pharma and life sciences with patient-level journey analytics—an emerging RWD infrastructure comparable in model to MDV's analyzer platform, though at a US-centric scale.
• Truveta: Truveta is an emerging US health-system consortium pooling EHR-derived RWD for pharma and research use—a comparable model to MDV's hospital-consortium approach in Japan, but at an earlier stage and with US academic-medical-center partners.

Broad incumbents

• Oracle Health (formerly Cerner): Oracle Health combines hospital EHR/clinical data systems with a broader data and analytics portfolio serving providers and pharma; it is a broader incumbent but competes with MDV's hospital management solutions and analytics tools in the same buyer organizations.
• IQVIA: IQVIA is the global incumbent in clinical and real-world data for life sciences, offering pharma RWE, epidemiology, and outcomes analytics that overlap with MDV's offerings to Japanese pharmaceutical customers; both monetize large proprietary RWD assets via enterprise subscriptions.

Regional players

• DeSC Healthcare: DeSC Healthcare is a Japan-focused digital health company that partners with MDV on data-supported research under the Nippon Life umbrella; it overlaps with MDV in Japanese population-health and personal-health-record data use cases for insurers and consumers.
