Hasegawa Naika Clinic

Hasegawa Naika Clinic is an internal medicine and gastroenterology practice in Hodogaya Ward, Yokohama, led by Director Shinichi Hasegawa, a physician with a background in gastrointestinal surgery and oncology. Beyond general internal medicine, the clinic runs endoscopy services (upper and lower GI scopes with same-day polyp removal) and hosts specialist outpatient clinics in cardiology, neurology, dermatology, and urology staffed by visiting specialists. The clinic relocated in 2023 to a larger, newly built facility with an isolated examination room for infectious cases, and it offers a free shuttle bus, on-site parking, and Saturday afternoon hours to make visits easier for local residents.
