Located on the 3rd floor of the NCO Sapporo Station North Building, directly connected to JR Sapporo Station's north exit, Sapporo Internal Medicine & Rheumatology/Collagen Disease Clinic specializes in internal medicine focusing on rheumatic and collagen diseases. The clinic features board-certified rheumatologists and rheumatology instructors certified by the Japan College of Rheumatology, providing care that leverages extensive clinical experience gained at Hokkaido University and regional core hospitals. Notably, the clinic has introduced joint ultrasound, which is effective for detecting rheumatism that is difficult to diagnose through blood tests alone. While ultrasound examination of fine joints requires advanced technical skill and experience, the clinic offers highly reliable diagnostic capabilities. Given that collagen diseases are often difficult to diagnose and treat, the clinic prioritizes early detection and early treatment, and also provides second opinions for patients who have questions about diagnoses from other facilities. Wednesday afternoon sessions are led by a female physician, creating an environment where patients can consult comfortably about sensitive symptoms and women's health issues. English language services are available, and various payment methods including credit cards, debit cards, and electronic money are accepted. Barrier-free facilities are also provided.
