#1. Foreword by Yukihiro Takahashi, President of JpGU

We will start accepting session proposals for the JpGU Meeting 2024
from 2 October.

I think that the majority of JpGU members participate in fall meetings
organized by JpGU member societies. I know that giving presentations
and asking questions primarily in Japanese, the native language, will
help many Japanese people engage in highly detailed discussions. Also,
I think that it is important to talk with longtime friends. On the
other hand, science is like an amoeba that changes its appearance, and
its internal structure is like a fluid, with multiple areas changing
their boundaries and continuing to grow through repeated integration
and division. We, scientists, strive to be more creative in our work
every day, and I’ve heard that creativity comes from connecting two
different concepts and/or methods. Of course, there are many situations
and phases in which research pursues a single subject deeply and
precisely, and its importance goes without saying. However, if we
expand the time scale, we can infer that the knowledge and/or methods
of other fields will inevitably give rise to new research field and at
the same time deepen our understanding. Earth and planetary science is
a field of study that deals with all phenomena that occur on the earth
and space, including life, at least in the solar system, and is
extremely diverse and dynamic in terms of both its subjects and methods.
We hope that JpGU will embrace all of this diversity and be not only
a place for internal organizational interaction, but also change its
external boundaries and promote new creations with related fields.
For JpGU meeting, I hope that you will also propose sessions that are
a little different from those offered at individual societies. Please
feel free to use the JpGU as platform for joint proposals with foreign
researchers, joint session within a science section, collaborations
with other science sections, and fields that go beyond the so-called
fundamental sciences, such as engineering and agriculture. I would be
happy if you could use it with your ideas.

By the way, this is an election year. We are currently accepting
applications for candidates for representative elections, and the
deadline is September 13th at 17:00. If you are interested in making
a contribution to JpGU, please consider submitting your candidacy.
Regardless of the size of the research field, and from the perspective
of gender and diversity, we hope for the active participation of a
variety of people, including young people, women, and foreign nationals.

#4. To JpGU Meeting 2023 Participation ID Holders

The “Meeting participation ID” is a six-digit ID starting with 23-,
specifically for the purpose of the participation in the JpGU Meeting
2023. These IDs will expire on Friday, 29 September 2023.Please visit
our website in October to obtain the participation ID for the JpGU

#5. To AGU members who have acquired a JpGU ID from the AGU membership system

Those who have obtained a JpGU ID from the AGU membership system
will have their AGU membership verified after each year’s JpGU meeting,
and the JpGU IDs will be deleted if their status is no longer valid.
This year, we will check your membership status as of 21 September, and
those with invalid status will have their JpGU IDs deleted on 29 September.
