Go To ICC2021 Online Meeting Website

Dear Colleagues,


Following the continuing uncertainty of the pandemic development, the ICC2021 annual meeting is going online, jointly organized by Keio University School of Medicine and Osaka University.


It is a pity that we cannot treat the ICC members to the beautiful gardens and Japanese food in Tokyo. However, there are some advantages that only online meetings can offer.


You can have exciting lectures of the world's leading scientists in the live session, and during the ICC2021 weeks, you can access to the latest research on centenarian on demand at home or at the office wherever you are comfortable.


Thanks to the support of Keio Global Research Institute, Osaka University and The NOVARTIS Foundation (Japan) for the Promotion of Science, we can have a significantly reduced registration fee!


We have kept registration fees as low as possible, with lower rate for students. We hope this means that even more of our members can participate this year.


Abstract submission is now open, for more information please visit our website.


We warmly e-welcome all researchers, students, and practitioners from multiple discipline of centenarian study and we invite you to join us to update and exchange knowledge and experiences.

ICC2021 WEB conference is supported by Keio Global Research Institute (KGRI), Osaka University Graduate School of Human Sciences Center for collaborative future creation project aging and death study Lab (CCFC), and The NOVARTIS Foundation (Japan) for the Promotion of Science.


The International Centenarian Consortium (ICC) was first conceived among centenarian researchers at the 14th World Congress of Gerontology and Geriatrics in Acapulco, 1989.  During our (mostly) annual meetings we have shared recent information and research on centenarians, fostering collaborations and friendships among different centenarian research teams. In our opening remarks for the 26th meeting of the ICC, we want to remember and acknowledge the founders as well as to capture the activities in the first few years of the ICC. We are proud of the annual tradition of sharing new research ideas as well as welcoming the next generations of centenarian researchers.
