Ajirogi-kai Social Welfare Corporation

Uji Hospital operates as a medical facility providing healthcare services to the local population in Japan. The hospital delivers a range of clinical services that include diagnosis, treatment, and ongoing patient care. It offers both inpatient and outpatient departments to accommodate varying medical needs. Services are provided by physicians, nurses, and allied health professionals employed at the institution. The institution functions under the organizational umbrella of the Ajirogi‑kai Social Welfare Corporation.

As a social welfare corporation, Ajirogi‑kai places its primary emphasis on public welfare rather than profit generation. This legal status signals a commitment to reinvest any surplus into community health initiatives and facility improvements. The corporation’s governance structure is oriented toward social responsibility which shapes the hospital’s operational priorities. Such a model distinguishes Uji Hospital from privately owned, investor‑driven healthcare providers in the region. The welfare‑based framework guides decisions about service scope, staffing, and outreach programs.

On January 6 2023, Uji Hospital experienced a ransomware attack that encrypted parts of its information technology systems. The attackers issued a ransom demand and there was evidence of external data communication after the encryption, suggesting possible exfiltration of personal information. The data potentially exposed included names and contact details of patients as well as current and former staff members. Although no confirmed misuse of the information was identified at the time of public disclosure, the hospital acknowledged it could not definitively rule out a leak. In response, the organization set up a dedicated communication channel for affected individuals and issued formal apologies to those impacted by the incident.
