At JpGU, we call co-sponsored sessions with our partner Unions "Joint Session".
【Partner Unions】
●AGU (American Geophysical Union)
●AOGS (Asia Oceania Geosciences Society)
●EGU (European Geosciences Union)
●CGU (Chinese Geoscience Union, Taipei)

Joint Session proposals need to be accepted by the co-sponsoring Unions to be designated as Joint Session.

・All session conveners of Joint Sessions must be JpGU ID holders, regardless of the ID category.

・The session must be proposed as E session.

【Rule for AGU】
・At least one of the conveners or contact persons must be an AGU Member in the 2025 meeting.

【Additional Rule for AOGS】
To propose a session joint with AOGS, follow the additional rules as follows:

・The conveners are from 2 or more different countries.

The Program Committee will finalize the acceptance based on the result of their approval.

・JpGU does not provide financial support such as travels to Joint Sessions.

・Joint Session proposals will be treated equally as other session proposals in organizing the Program such as the number of assigned time slots.

Sessions co-sponsored or co-organized with our society members are designated as "Co-sponsored Sessions" at JpGU Meetings.

・Co-sponsored sessions must follow the guidelines/regulations of the co-sponsoring society, if any. JpGU does not require a certain condition.

・Conveners must
(1) propose a session from the JpGU session proposal system and (2) contact the representatives of the society members regarding their request during the session proposal period.

・After the session proposal period is over, JpGU will receive a list of Co-sponsored session from each of the society members.
Only sessions listed there will be considered and promoted as Co-sponsored sessions.
JpGU does not accept nor approve direct requests from the conveners.

・All communication regarding co-sponsored sessions must be done directly between the conveners and the representatives of each society.

・The session will be listed as a Co-sponsored session together with the name of the co-sponsoring society on the JpGU website.

・The representatives of each society are listed in the Organization page.

・Inquiries including the contact address of the representative must be sent directly to the society.

Among the sessions proposed jointly with organizations, etc. that do not belong to JpGU Society Members (including overseas societies other than Partner Unions), those that are related to the Science Council of Japan or deemed to be of particularly high public interest may be held as co-sponsored sessions after deliberation by the JpGU Board of Directors. Sessions jointly proposed with overseas academic societies other than Partner Unions shall be designated as "International Cooperative Sessions."

・The session must be proposed by an organization that is not a JpGU Society Members (including overseas academic societies other than Partner Unions).

・Proposals that are related to the Science Council of Japan or that are deemed to be particularly public and appropriate for co-sponsoring as activities to expand mutual cooperation with overseas academic societies.

(Please submit your application by the deadline of 10 November, as it requires time for the Board of Directors to approve your application.)

・After the session proposal deadline, the session will be finally approved as a co-sponsored session after deliberation by the Board of Directors.

・If the session is not approved as a co-sponsored session, the convener will be notified accordingly. However, the session proposal itself cannot be withdrawn because it was not approved as a co-sponsored session (the session will be held as a regular session).

・The name of the co-sponsoring society will be listed in each session details.
