Dr. Keisuke Miyamoto is a dual-licensed physician in both the United States and Japan, with board certification in Internal Medicine in both countries. In Japan, he is also a specialist in Pulmonology and Thoracic Oncology. He holds the distinction of being Japan’s first diplomate of the American Board of Lifestyle Medicine, helping lead the growth of this field throughout the country. He currently serves as Assistant Clinical Professor of Medicine at the John A. Burns School of Medicine (JABSOM), Associate Professor and Lecturer at Keio University’s Center for Preventive Medicine, and as a Board Member and Consultant for the Japanese Society of Lifestyle Medicine.

His work is rooted in the belief that health should not be defined only by the absence of disease, but by the presence of energy, purpose, and long-term well-being. He champions a life-course approach to care, focusing on prevention and personalized lifestyle strategies that help people avoid chronic illness before it starts.

At the heart of Dr. Miyamoto’s philosophy is the idea that brain health is key to lasting change. He supports patients in building cognitive and emotional resilience through sleep, nutrition, movement, stress recovery, and meaningful social connection. His goal is to give people the mental clarity and motivation they need to reshape daily habits and live more fully.

Dr. Miyamoto has worked across a wide range of healthcare settings, from critical care units to community-based programs. He brings together biomedical science with practical, evidence-informed tools to help people perform at their best throughout all stages of life. His approach draws from neuroscience, behavioral science, lifestyle and longevity medicine, and public health, with special attention to how culture and environment shape behavior.

He continues to advise medical schools and institutions in both Japan and the United States, guiding translational research and mentoring emerging leaders in the field. Dr. Miyamoto envisions a future where healthcare is designed to keep people well, not just treat them once they are sick.
