Tokyo Talks: A ‘Sunny’ Perspective on Paediatric IBD in Japan (with Prof Arai)

In this episode of THE PIBD Digest, we travel to Tokyo for an inspiring and uplifting conversation with Professor Katsuhiro Arai or “Sunny” —a paediatric gastroenterologist whose warmth is as striking as his scientific expertise. Sunny is also President-Elect of the Asia Pacific Society for Paediatric Gastroenterology, Hepatology and Nutrition, and Chair of its Scientific Committee. With trademark enthusiasm and infectious positivity, Sunny shares insights into paediatric inflammatory bowel disease in Japan, including the national IBD registry, emerging PIBD trends, and how data is shaping better care for children. What really stands out is Sunny’s deep passion for the psychological wellbeing of patients and their families—reminding us that caring for children with IBD means supporting hearts and minds, not just guts. Full of wisdom, and that unmistakable ‘Sunny’ sparkle, this episode is a joyful reminder that compassion and connection are just as powerful as medicine.
