Murata Circulatory Internal Medicine Clinic, operated by Medical Corporation Wayokai, is a specialized circulatory internal medicine clinic established in January 2012 in Nishitakadomari, Sanyo-Onoda City, Yamaguchi Prefecture. Located approximately 10 minutes by car from the Sanyo Expressway Onoda IC and about 5 minutes by car from the JR Sanyo Main Line Onoda Station, the clinic enjoys excellent transportation access. Leveraging extensive clinical experience focused on heart disease, the clinic aims to provide detailed medical care while minimizing long wait times typical of large hospitals. Recognizing that accurate diagnosis and promptness are crucial in heart disease treatment, the clinic performs immediate ultrasound examinations and 24-hour ECG for arrhythmia diagnosis, with a system in place to provide clear explanations of test results on the same day. For examinations or hospitalizations that cannot be handled in-house, the clinic has established a rapid referral system in close coordination with nearby hospitals. The medical department focuses on internal medicine, providing comprehensive care for heart disease diagnosis and treatment as well as managing lifestyle-related conditions like hypertension, dyslipidemia, and diabetes. Operating hours are 9:00-12:30 and 14:00-18:00 on weekdays, with Sunday and national holidays as closed days. The clinic offers English language support, accepts credit cards and electronic payments, and provides parking and barrier-free facilities to accommodate patient needs.
