#1. Preface by Eiichi Tajika, President of JpGU

The JpGU-AGU Joint Meeting 2020: Virtual was the 30th anniversary
since the 1st Joint Meeting of Earth and Planetary Science Societies
of Japan held in 1990 and the 2nd Joint Meeting with the American
Geophysical Union (AGU). As you will be aware, the meeting had to be
postponed by 7 weeks due to Covid-19, and was held from July 12 to 19
and was held entirely online. This was an unprecedented challenge for
us and many aspects we were trying for the first time. Our primary
concern was to provide an opportunity for researchers, in particular
students to present the results of their research and with this in
mind decided to hold a virtual meeting rather than cancelation.
We apologize for all the inconvenience caused to the participants
due to the system trouble with the aMuze iPoster system both before
and on the first day of the meeting. We are also deeply sorry for
difficulties experienced by some participants caused by the large
number of people accessing the portal site on the first day.
After these initial problems, we were able to complete the planned
program without any further serious trouble. Despite being a virtual
conference, the total number of participants is about 6,000, making
it the largest virtual international conference in the world to date,
at least, in the field of Earth and planetary sciences. I would like to
express my sincere gratitude to the meeting organizing committee,
the online hosting core group, the JpGU office, the faculty and
students who operated Zoom host, and all the other people including
participants who have contributed to the success of this virtual

The 2020 Annual Meeting of JpGU Representatives was held shortly
after the meeting and 20 members were appointed as Directors for the
8th term. At the following new Directors meeting, I was chosen as the
new President of JpGU. It is a great honor to serve as president of
such a large organization with over 11,000 members. At the same time,
I keenly feel the weight of this responsibility.

The Covid-19 pandemic has changed the world, and academic communities
and academic activities are no exception. This is now a time of flux
as we reach out to find new ways of conducting academic activities.
At such a time, it was only with great trepidation that I agreed to
take on the challenge of becoming the next president of JpGU. With
the support of the strong team of New Directors their experience and
insight I would like to accept this role and do my best to manage JpGU
for the next two years. On behalf of the new team, I also ask you,
the members, for your support and cooperation as we move forward in
these difficult times.

JpGU is an organization established with the aim of promoting the
development of Earth and planetary sciences throughout the world and
to bring together the wide range of associated activities and academic
societies in Japan. Your insights and wisdom are of great importance
to us as we develop JpGU. We gladly receive proposals that have the
potential to contribute to the development of the Earth and planetary
science community as a whole. If you have constructive ideas or wish
to contribute to committee activities of JpGU, please feel free to
contact the JpGU office.
We greatly appreciate your support and cooperation.

Award and Excellence in Research Award are given. In addition to this,
we have established a new prize, the Outstanding Poster Presentation Award this year.
Congratulations to all presenters for your great achievement.
