B-leaf Medical Internal Medicine & Pediatrics Clinic, located in Onozaki, Tsukuba City, Ibaraki Prefecture, provides internal medicine and pediatric care led by a physician certified in general medicine. The clinic's distinctive approach centers on "general practice" rather than being limited to specific medical departments. They address a wide range of conditions from common symptoms such as colds, abdominal pain, headaches, and dizziness, to management of chronic diseases including hypertension, diabetes, dyslipidemia, and dementia. They also provide follow-up care for school refusal, orthostatic dysregulation, and developmental disorders, making referrals to appropriate specialized medical institutions according to patients' conditions. For suspected infectious diseases, they operate a drive-through fever clinic where patients can undergo examinations and tests without entering the facility, with systems in place to prevent nosocomial infections. Furthermore, they actively promote medical digital transformation including online consultations, online reservations, and telemedicine, creating an accessible environment for working adults who may find it difficult to schedule clinic visits. English consultations are available, and they accept credit cards, debit cards, and electronic payments. The clinic is also equipped with barrier-free facilities and a dedicated parking lot. The clinic can be accessed via bus from Tsukuba Express Tsukuba Station.
