How donations are used
Diabetes is a well-known disease, but it is not well known in Japan that there are different types of diabetes, such as Type 1 and Type 2 diabetes. Most diabetics have “Type 2 diabetes,” for which diet and exercise are the basis of treatment; Type 1 diabetes accounts for only a few percent of all diabetics in Japan, and it often occurs even in children. Once developed, it is an incurable disease requiring insulin therapy of 4-5 injections daily for the rest of one’s life.
The funds will be used to support research to make Type 1 diabetes a “curable disease” and support activities for Type 1 diabetes patients with various needs, from children to the elderly.
Participation Procedures&Schedule
＊The donation and entry fee payment period for the Japan IDDM Network is from Tuesday, July 15 to Wednesday, August 13, 2025.
