About JpGU 2023


JpGU Meeting 2023 Chair

Wanglin YAN (Keio University)
JpGU is a large organization of 51 academic councils related to earth and planetary sciences with about 10,000 members. Before the pandemic, we have seen about 8,000 participants every year in Makuhari, enjoying beer in the poster hall and wandering around the exhibition hall looking for souvenirs, literally a festival of earth and planetary sciences. Since 2020, the breakout of COVID-19 restricted face-to-face meetings. The waves of infection have forced the meeting to be held two years in a row in a completely online format, and the 2022 meeting conducted a hybrid format for the first time. Despite these restrictions, we were able to welcome as many participants and presenters as before without losing out to the coronavirus. I am sure that everyone involved in the meeting management must have worked very hard to organize the meeting. I would like to express my sincere appreciation for their efforts.

Although many cases of infection have been seen in the Asian region recently, it appears that the situation has reached a plateau and is heading toward a lull. In light of this situation, the annual meeting 2023 is planned to be held in a hybrid format as the meeting 2022. Compared to the online-only format, this will provide more opportunities for face-to-face interactions, which is very welcome.

On the other hand, regardless of the coronavirus situation, I believe that hybrid meetings will become the new normal for future congresses. By taking advantage of the merits of both, work and travel schedules can be made more flexible. Although this may place a burden on the meeting management, we hope that the new tools for managing content and promoting communication will bring convenience as well as new experiences and insights to the participants, and we hope that you will join and enjoy the meeting again.

We will try to provide you with up-to-date information so that you can choose whether to participate on-site or online at the appropriate time and in the appropriate way. We encourage you to apply regardless of the form of participation and look forward to lively discussions both onsite and online.


JpGU Meeting 2023 Program Committee Chair

Tetsuya TAKEMI (Disaster Prevention Research Institute, Kyoto University)
We are now accepting session proposals for and moving forward to JpGU Meeting 2023. JpGU2023 will be held in a hybrid mode with in-person meetings at Makuhari Messe in Chiba and online attendance.

More than two years and a half have passes since the outbreak of COVID-19 in 2020, and online communications have become a daily scenery. Nonetheless, the value of in-person communications is now recognized. In the past JpGU meeting in 2022, well-designed sessions combining the merits of both in-person meetings and online communications were organized through seeking an updated JpGU meeting in the with-/post-COVID19 era, although there were comments on the long duration of JpGU2022.

As in JpGU2022, JpGU2023 will consist of hybrid oral sessions and in-person/online poster sessions; all the sessions in JpGU2023 will take place within a week. We, JpGU2023 Program Committee, will make the best effort to organize sessions that would stimulate interactions among in-person and online attendees by providing platforms for the presentations of both oral and online modes and for in-person and online discussion. In order to enhance scientific discussion among the attendees, we would ask conveners to propose well-designed, well-focused sessions and to structure their sessions to promote communications among in-person and online participants.

We, the JpGU2023 Program Committee members, are willing to contribute to making JpGU2023 a successful meeting with a lot of scientifically attractive sessions and with high satisfaction in the advantages of both in-person and online communications.
