We are sorry to announce that the registration for IUI-2018 is closed, and the Late Registration and Onsite Registration will not open. We have had a tremendous number of participants registering for the conference and reached the capacity of the venue ("Hitotsubashi Hall") already at the Early Registration stage. We unfortunately cannot accept further participants due to the safety and security requirements of the venue. We thank you for your interest and sincerely apologize for not being able to accommodate more participants at IUI-2018.
