Oshima Clinic, located in Kamishiba-cho, Fukaya City, Saitama Prefecture, is a community-based medical facility specializing in internal medicine. In addition to general internal medicine, the clinic also offers hemodialysis, making it an accessible healthcare provider for patients requiring dialysis treatment due to conditions such as chronic renal failure. Notably, the scope of its dialysis services is exceptionally broad: even during periods when the general internal medicine outpatient clinic is closed for the New Year holidays, Obon, and national holidays, hemodialysis treatment continues as usual—a source of great reassurance for dialysis patients. General internal medicine outpatient services are closed on Saturdays, Sundays, and national holidays, with additional closures during the New Year period (December 30 to January 3) and the Obon holiday (five days in mid-August). The facility is equipped with a parking lot, providing convenient access by car. It is also designed to be barrier-free, making it easy for elderly patients and those requiring physical assistance to use. For residents of Fukaya City and surrounding areas seeking ongoing internal medicine care or dialysis treatment, Oshima Clinic is a reliable choice.
