The mission of the Department of Pediatrics is to provide the highest quality clinical practice for prevention and treatment in a wide range of childhood disease, generating new knowledge through scientific research. Combination of clinical and research activities in the Department has developed highly recognized achievements including the first successful human gene therapy in Japan for ADA-SCID conducted in 1995. For the next generation of medical trainees, a large patient population in all over Hokkaido and experts in every field of pediatrics offer a superb educational opportunity, enabling them to pursue flourishing career as a pediatrician as well as a researcher.

Research

The department has 10 research groups covering a wide range of pediatric disorders.
Immunology Group deals with immunodeficiency, allergy and collagen diseases. The group is renowned for the first successful human gene therapy in Japan.
Infectious Disease Group is well known for research in virology, including human metapneumovirus and human bocavirus.
Endocrinology Group is working on all aspects of pediatric endocrine disorders including growth problems, abnormal puberty, and diabetes mellitus.
Nephrology Group provides total care for patients with renal disorders including congenital anomalies, nephrotic syndrome, and renal failure.
Cardiology Group offers diagnosis and treatment for pediatric cardiac disorders including congenital heart disease, arrhythmia, and Kawasaki disease.
Hematology and Oncology Group functions as a center for diagnosis and treatment of patients with pediatric malignancy including leukemia/lymphoma and solid tumors, offering highly sophisticated blood stem cell transplantation.
Neurology Group takes care of patients with neurological disorders including developmental delay, epilepsy and muscular dystrophy. Neonatology Group offers intensive care for any problems of neonates including immature babies, congenital anomalies, and infection.
Medical Genetics and Dysmorphology Group offers diagnosis, management and genetic counseling for patients with genetic disorders.
Metabolic Disease Group deals with patients with congenital metabolic disorders and diseases in digestive system.

Education

We provide the best education for medical students. Our education program for undergraduate students features systematic lectures and clinical clerkship. Specialists covering every field of pediatrics provide an excellent opportunity to recognize the wide spectrum of clinical pediatrics.
Graduate students can work on a wide variety of research activities. Combination of clinical and research opportunity would promise a successful career not only in pediatrics but in basic science.
We offer the integrated 3-year Residency Program. The goal of the program is to obtain the board certification of pediatrics. The Program is supported by a collaborative effort with the University Hospital and related institutions in Hokkaido. Under this program, the core of general pediatrics training will be provided through the extensive clinical experience in these institutions.
