Program
International attendees have to give your talk in Japanese daytime. Sorry for this, but we will do our best for maximizing your convenience in terms of your time differences when we assign your talk to a session.
To increase comfortableness of every speaker from different time zones, each session will be organized taking account of the speaker’s time zone. Thus, a session will be a mixture of various topics that are irrespective of research fields. This is a big difference from the previous ITMs, but we hope this will help all attendants to contribute every topic on tunicate biology as in the previous onsite ITMs.
If you have proposal for round-table discussion and technical session, please contact us.
