Toda Medical Group

What Toda Medical Group does

Toda Medical Group (TMG / 戸田中央メディカルケアグループ) is a private integrated healthcare network headquartered in Toda City, Saitama Prefecture, Japan, founded in 1964 and operating under the leadership of Chairman Takashi Nakamura. The group provides acute care, rehabilitation, obstetrics, chronic dialysis, elderly care, health checkups, home healthcare, and pharmaceutical services through approximately 29 hospitals, 6 elderly care facilities, and around 120 related business offices spanning the 一都四県 (Tokyo, Saitama, Kanagawa, Chiba, and Shizuoka). Notable assets include the flagship 517-bed Toda Chuo General Hospital, the TMG Pharmacy Formulary knowledge system developed with Nanzando, and the TDR disaster medical response team of 153 members.

TMG's core service delivery is built around a vertically integrated care continuum that runs from emergency and acute hospitalization through recovery-phase rehabilitation, long-term nursing care, and home-based services. Underlying technology includes multi-facility web platforms, a centralized pharmacy formulary management system, a rehabilitation department portal, and a dedicated recruitment portal, supported by Microsoft Clarity and Google Analytics for web analytics. The group also maintains a formal AI usage policy and a comprehensive Business Continuity Plan (BCP) covering facility, area, and group levels for disaster preparedness. Recent operational technology additions include an IVR automated phone routing system deployed at Hokusu Shiroi Hospital in July 2026.

TMG operates as a direct-to-consumer healthcare provider under Japan's national health insurance (国民健康保険) and related public insurance schemes. Revenue is generated through per-diem DPC (Diagnosis Procedure Combination) reimbursement for acute inpatient stays and fee-for-service billing for outpatient, diagnostic, rehabilitation, dialysis, and home healthcare services, supplemented by patient co-payments and room differential fees for private rooms (for example, ¥12,000/day for single rooms at Hokusu Shiroi Hospital). The group recruits medical, nursing, pharmacy, rehabilitation, and administrative staff directly through its own careers website and TMG My Page platform, and reaches patients through its corporate website and social media channels (X, Instagram, YouTube, note).
