Mori Naika Clinic, located on the first floor of the JR Chuo Line Katsukawa Station South Exit Building, is a community-based medical facility specializing in internal medicine, diabetology, endocrinology, and pediatrics. The clinic places particular emphasis on diabetes and endocrine disorders, and offers ultrasound examinations starting early in the morning before regular clinic hours. Operating hours are weekdays from 8:45 AM to 12:30 PM and 4:15 PM to 7:00 PM, with Saturday morning sessions only. The clinic is closed on Wednesdays, Sundays, and public holidays. For patients with fever or cold symptoms, a dedicated entrance and a partitioned examination area have been established to prevent contact with general patients. The clinic also provides specific health checkups, late-stage elderly health screenings, and specific health guidance (motivational support), offering comprehensive health services including lifestyle disease prevention and management. English-language support is available, and the facility is wheelchair accessible. Patients arriving by car can use the multi-level parking lot at the station's south exit. The clinic has also implemented a face-recognition card reader system that accepts My Number cards for patient registration, demonstrating its commitment to improving patient convenience.
