    Symposia offer an opportunity for a focused talk session on a key area of research interest. The symposium organizer(s) should submit a proposal that will be evaluated by the local organizing commitee. It is not possible for the organizing committee to provide financial assistance to symposia. For accepted symposia, all symposium presenters are asked to submit their own abstract individually through the abstract submission system, which will open later. Please submit proposals by the end of Jan 2023 by email (ibac@sci.hokudai.ac.jp), as a single PDF that includes the following information: title of the symposium, the name(s) and affiliation(s) of the organizer(s) and the list of the presenters, and the brief outline of proposed topic (under 500 words). Each symposium is expected to include 4-6 talk presentations.
    Abstract submission
    We will start to accept abstract submission from Feb 2023.
