Dear Colleagues,

 Already 4 years has passed since the 4th International Moyamoya Meeting (IMM) was held in 2018. Since then, information sharing through international networks has been interrupted due to the COVID-19 outbreak. Therefore, we are pleased to announce that we have decided to organize this World Internet Conference on Moyamoya Disease (Winc Moyamoya) on October 12, 2022 as a novel platform for researchers of moyamoya disease to meet and discuss newly obtained knowledge from basic and clinical research in the past four years, using the Internet conference system that has greatly developed and spread in the past two years.

 Due to the time difference, overseas speakers will be asked to make their presentations at a time that is convenient for them. Even if you are unable to participate in real time due to the time difference or other reasons, you will be able to watch the conference and to join the discussion via the Internet for a certain period (not determined) after the conference.

 Now, all of us are faced to a very difficult and challenging time for these two years. We strongly hope that all of you are keeping healthy and we are looking forward to welcoming you and sharing novel information on moyamoya disease with you very soon.
