Located in the Kotoni area of Sapporo's Nishi Ward, Kotoni Heart Internal Medicine & Dialysis Clinic specializes in cardiology and dialysis. Accessible in about 15 minutes from central Sapporo by subway or taxi, the clinic offers parking and barrier-free facilities. For over 10 years, the clinic has been treating heart and vascular diseases and kidney conditions in the local area, building trust as a community primary care provider. In dialysis treatment, the clinic has introduced online HDF on all machines, which is expected to reduce complications and improve prognosis compared to conventional hemodialysis, while maintaining strict water quality management with high-purity dialysate. A key feature is the ability to provide safe dialysis treatment for patients with heart conditions, leveraging cardiology expertise. For heart disease patients, a cardiovascular rehabilitation room is available to support postoperative respiratory and circulatory recovery. For shunt management, the clinic uses the latest X-ray equipment for angiography and PTA, ensuring prompt response to emergencies. The clinic supports English communication and can refer to nearby affiliated hospitals if hospitalization is required, creating an environment where first-time patients can continue treatment with peace of mind.
