Tsuda Clinic, operated by the medical corporation Sanninkai, is a community-oriented internal medicine clinic located in Matsubushi Town, Kitakatsushika District, Saitama Prefecture. Situated in a residential area of Matsubushi Town, the clinic has long supported the everyday health management of local residents. Covering the full scope of internal medicine, it addresses a wide range of health concerns—from acute conditions such as colds and fevers to the ongoing management of lifestyle-related diseases including hypertension, diabetes, and dyslipidemia. Clinic hours run from 9:00 AM to 6:00 PM, with closures on Sundays and national holidays, Saturday afternoons, the year-end and New Year period (December 29–January 3), and the Obon season (August 13–15). Because it operates nearly all day on weekdays, the schedule is well suited for working patients as well. The clinic has a parking lot, making access by car straightforward—a convenience characteristic of suburban locations. Barrier-free design ensures that elderly patients and those with limited mobility can visit with ease and confidence. As a family doctor that continually supports community health, Tsuda Clinic serves as a vital provider of primary care in Matsubushi Town.
