Dr. Takuji Shirasawa is an anti-aging practitioner at Ochanomizu Longevity Clinic and Director and Researcher at Shirasawa Anti-Aging Medical Research Institute. He previously taught Aging Control Medicine at Juntendo University Graduate School of Medicine, Japan. He got his Ph.D. He holds a Ph.D. in Immunology from Chiba University Graduate School of Medicine and has spent the past 30 years researching molecular genetics in molecular pathology and gerontology.

His personal interests are the molecular biology of aging and gerontology, the molecular genetics of Alzheimer's disease, the analysis of motor genes, stem cell research, telomere research, his diet ketogenic, and diabetes in a breakthrough way. We are dedicated to identifying and addressing the root causes of chronic diseases such as A whole system of dietary and medical approaches called functional medicine. Through his practice, teaching commitment, writing, research, and advocacy, he empowers people to start treating the underlying causes of disease, not just managing symptoms.
