Mediva

What Mediva does

Mediva Inc. (株式会社メディヴァ) is a privately held Japanese healthcare and long-term care consulting firm founded in 2000 and headquartered in Setagaya, Tokyo, with a secondary consulting hub in Fukuoka. The firm serves medical institutions (hospitals, clinics), elderly care operators, health insurance associations and corporate employers, healthcare-adjacent enterprises, government and prefectural bodies, and overseas clients across ASEAN and China. Across these segments, Mediva delivers management consulting, operational transformation, and digital-execution support spanning roughly seven practice areas, including business succession and M&A advisory for medical corporations and nursing-care operators. The company also owns and operates a small portfolio of medical facilities (Sakura-Shinmachi Urban Clinic, Matsubara Urban Clinic, Matsubara Nurse Care Station, Dozen Hospital) that function as both service-delivery units and pilot sites for its methodologies.

Mediva's technology stack combines proprietary software with hands-on operating expertise. The firm's core digital products are WellaboSWP, a cloud-based corporate health management system co-developed with Honest Corporation and deployed via subscription; MIERU, a smartphone-based internal workload measurement app for medical institutions priced at ¥1,000/device/day; and Dementia Eyes, a patent-pending AR tool developed with Keio University Graduate School of Media Design that simulates visual impairments associated with dementia. Operational deployments include RPA-based workflow automation and generative-AI-assisted task shifting inside Mediva-owned clinics. The firm maintains brand sub-portfolios such as プラタナス (Platanus), which houses operating-related facilities, and ウェルabo (Welabo) for online health management services.

The business model combines professional-services consulting (typically quote-based for hospital, elderly-care, government, and M&A engagements) with subscription and usage-based revenue from WellaboSWP and MIERU. Sales are conducted directly to institutional clients through relationship-driven engagement, with supporting pipeline generated via content marketing (~100+ tagged blog topics), academic-conference participation (Japan Primary Care Association, Japan Association for Home Medicine), and earned-media appearances including NHK. Government commissions (Setagaya Ward, Nerima Ward, Chiba Prefecture, Fukuoka City) function as multi-year anchor mandates. Leadership is founder-controlled under CEO Kanoko Oishi, with Director Daisuke Komatsu responsible for consulting practice and Director Iwasaki Katsuji (ex-McKinsey) on the management team; no outside investors, parent entities, or public listings are disclosed.
