Higashimotomachi Naika Clinic, located on the 3rd floor of a medical building along the main bus route about a 5-minute drive from the south exit of Kokubunji Station toward Fuchu in Tokyo, is a community-oriented primary care clinic operated by Medical Corporation Keijinkai. Focusing on lifestyle diseases such as hypertension, hyperlipidemia, and diabetes, the clinic also provides dementia care and smoking cessation outpatient services, functioning as a comprehensive gateway for a wide range of internal medicine conditions. Director Michiko Koizumi is a certified General Internal Medicine Specialist of the Japanese Society of Internal Medicine. Rather than relying solely on test data, she carefully combines thorough medical interviews with physical examinations to deliver attentive, patient-centered care tailored to each individual. The clinic offers a wide array of on-site examinations including X-ray, electrocardiogram, bone density testing, Holter monitoring (24-hour ECG), and sleep apnea screening, as well as nutritional counseling and vaccinations. It collaborates with orthopedic and otolaryngology clinics in the same building, enabling smooth cross-specialty referrals. Many staff members have served for over 10 years, creating a warm, home-like atmosphere. With parking and barrier-free access, the clinic provides an environment easily accessible to a wide range of patients.
