It was announced through our News Letter on February 16, 2021 that the March Study Meeting would be held on March 13. But as the news media informs, the state of emergency in the Tokyo metropolitan area has been extended and it won’t be lifted before the day expected for this meeting. Therefore, we regret to announce that the March Study Meeting will be canceled. We apologise in particular to the members who completed the pre-registration already, but we are very grateful for your kind understanding. We are looking forward to seeing you next time.
