NanbyoData aggregates rare disease information from a variety of perspectives, including basic research, clinical data, and real-world disease scenarios, all presented in Japanese.

Accumulating information on nanbyo diseases from around the world

NanbyoData compiles rare disease information from around the world, featuring the latest updates from global medical databases and information sites.

Updateing information on nanbyo diseases

NanbyoData plans to publish information on rare diseases targeting the Japanese population, incorporating findings from past research and studies, as well as unique epidemiological data from large-scale medical databases.


In Japan, rare diseases are addressed through two specific healthcare schemes: the "Designated Intractable Diseases" system and the "Specified Chronic Diseases of Children" system. As of July 2021, these systems cover 333 and 762 diseases, respectively. The Nanbyo Disease Ontology (NANDO) is the first ontology that systematizes the disease concepts and relationships among the diseases targeted by Japan's rare disease policies. NanbyoData utilizes NANDO to gather and provide data on rare diseases both domestically and internationally. The vocabulary list and hierarchical structure of NANDO can be accessed as the follow:
