The 3DAHM 2021 Symposium (held online) has been successfully completed on May 28, 2021. First of all, thank you very much to all the participants and staff. This was the first online symposium in the history of 3DAHM. I heard that there were 67 presentations from 13 countries and more than 150 researchers all over the world participated and spent at least 17.5 hours engaging with the meeting. The baton of the 3DAHM has been passed on to the Tokyo Symposium in 2022. I look forward to seeing you all in Tokyo next year!!
