I am a pediatrician and neonatologist who leads the neonatal intensive care unit at Showa Medical University Koto Toyosu Hospital, Japan. My clinical and research interests focus on the developmental origins of health and disease (DOHaD), particularly how fetal and early postnatal environments shape growth, body composition, and long-term metabolic health. My research encompasses nutrition and growth in preterm and very low birth weight infants, adipose tissue development and expandability, adiponectin, advanced glycation end products, and brain growth and neurodevelopment. Through neonatal care and long-term follow-up, I seek to connect early nutritional and developmental trajectories with health outcomes across the life course. My publications include original research and reviews on low birth weight, adipose tissue biology, and the developmental basis of later metabolic vulnerability.
