Otsuka Internal Medicine Clinic (Gastroenterology / Nephrology)
About
Otsuka Internal Medicine Clinic, located in Umazon, Tsukuba City, Ibaraki Prefecture, is a community-focused clinic specializing in gastroenterology and nephrology. The clinic director, Dr. Koichiro Otsuka, studied medicine at the University of Tsukuba before gaining extensive experience as a nephrologist in Nagasaki, including approximately one and a half years providing medical care on remote islands. After gaining experience in multiple specialties including diabetes and endocrinology, as well as collagen disease and rheumatology, he further honed his skills in gastroenterology at Tsukuba Memorial Hospital, establishing a system capable of addressing a wide range of internal medicine conditions. The clinic offers various in-house examinations, including gastroscopy, colonoscopy, abdominal ultrasound, echocardiography, and X-rays, emphasizing early diagnosis before symptoms become apparent. Since October 2025, the clinic has established appointment-only afternoon clinics on the first and second Wednesdays of each month, staffed by a specialist in diabetes and metabolic medicine, further expanding its capacity to meet specialized healthcare needs. The facility features 21 parking spaces and barrier-free accessibility, and accepts patients until 4:00 PM on Saturdays to accommodate those who find weekday visits challenging. In addition to English-language services, the clinic accepts credit cards and electronic payments, providing a system that responds broadly to the diverse needs of patients.
