Doctor introduction

HAYATO KATO
Nice to meet you. My name is Hayato Kato, and I am the director of 88 Internal Medicine Clinic. Since opening in Bakuro-cho in April 2025, we have been visited by many people and have steadily grown as a clinic that supports the health of local residents. I gained experience mainly in diabetes treatment at a university hospital, and then worked in a wide range of general internal medicine and lifestyle-related disease treatment at flagship hospitals and specialized clinics.
Through this clinical experience, I realized how important it is to have an internist who is closer to you and whom you can consult with casually.
At our clinic, we don’t just look at symptoms, but also take into account your lifestyle and feelings, striving to provide medical care that is tailored to each individual. We want to be a place where you can consult with confidence about anything from minor changes in your health to managing chronic diseases. We will continue to value careful examinations and easy-to-understand explanations, and aim to be a clinic that can provide long-term support for your health. Please feel free to consult us.
