Taichi Kido, EY-Parthenon Partner, EYSC comments:
"This survey of healthcare professionals involved in rare diseases highlights several challenges, such as building research and development environments, increasing awareness and understanding, and personnel training. These are in addition to a need for funding for basic and applied research, and establishing early diagnosis systems in clinical practice. It also identifies the lack of treatment and diagnostic options in Japan compared to other countries. To meet the 'Expectations of Stakeholders' outlined in this survey, it is vital that all stakeholders in the medical system act collectively not only to envision ideal scenarios but also to make progress on concrete actions and collaborations. At EYSC, we hope that this survey will serve as a catalyst for those initiatives. We are committed to building a better working world for everyone involved in rare diseases."

2. What are Rare Diseases?
Rare diseases are separate medical conditions which affect an extremely limited number of patients. However, it is estimated that there are over 7,000 rare diseases worldwide, affecting a total of 300 million people. Definitions vary by country but, according to the "Designation System of Orphan Drugs/ Medical Devices," based on the “Act on Securing Quality, Efficacy and Safety of Products Including Pharmaceuticals and Medical Devices” in Japan, the designation criteria include "having fewer than 50,000 patients in the country, high medical needs and high potential for development." In the United States, the threshold is fewer than 200,000 patients whereas in Europe, the ratio is fewer than 5 patients per 10,000 population. In addition to affecting a small number of patients, these diseases are often severe and difficult to treat due to unknown mechanisms of onset, resulting in limited effective treatments.
