Motoji Naika Clinic, located in Miyamachi, Fuchu City, Tokyo, is an internal medicine specialty clinic opened in 2007 by Director Dr. Keisuke Motoji, who trained for 16 years in the First Department of Internal Medicine at Yokohama City University School of Medicine. The director holds certifications as a specialist and supervisory physician from the Japan College of Rheumatology and as a specialist from the Japanese Society of Allergology, demonstrating high expertise in the diagnosis and treatment of rheumatic diseases including rheumatoid arthritis, as well as allergic conditions such as hay fever and bronchial asthma. The clinic's policy extends beyond treating the diseases themselves to comprehensively managing complications, covering a wide range of internal medicine conditions including cardiovascular, respiratory, gastrointestinal, and diabetic disorders. The clinic also has multiple internists on staff, including Dr. Toshiko Motoji, former chief professor of hematology at Tokyo Women's Medical University, and Dr. Tokue Yamato, who specializes in rheumatology and dialysis, enabling a multifaceted clinical approach. For cases requiring advanced testing or hospitalization, the clinic has established a referral network with appropriate institutions such as Tokyo Metropolitan Fuchu Hospital and Kyorin University Hospital, providing community-based comprehensive internal medicine care.
