#1. Foreword by Simon Wallis, President of JpGU (2025-2026)

A successful JpGU 2025 meeting ended with a real sense of accomplishment in the air—and for good reason. This year’s meeting welcomed over 9,300 participants, our highest attendance to date. Alongside the rich tapestry of scientific presentations, attendees enjoyed a diverse program of events, a reimagined party, and even a new photo spot that quickly gained popularity.

My heartfelt thanks to the many individuals who made this meeting possible. The tireless efforts of our section and committee members, staff, and especially the meeting organizing　 committee led by Wada-san, deserve special recognition. It is no easy feat to weave together hundreds of sessions, special lectures, and activities into the seamless experience we witnessed. Their work behind the scenes ensured the meeting’s success.

One moment that stood out to me personally was the welcome with a smile I received from student staff each time I stepped into the venue. It may be a small gesture, but it contributes to the making of a great atmosphere—thank you!

We were also delighted to welcome the largest number of high school students in the history of JpGU. This surge in youth interest was no doubt inspired in part by the popular book and NHK drama Classroom in the sky, which follows high school students fascinated by Martian geology. The show culminated in a fictional JpGU presentation—one that clearly resonated with young viewers. We were honored to host the book’s author, Shin Iyohara, again at this year’s meeting. Like many others, I lined up to have a copy signed—a great personal souvenir.

Looking to the next meeting there is a lot to look forward to. On the final day of the meeting, we signed an agreement with the American Geophysical Union (AGU) to co-host next year’s joint meeting. While the geopolitical landscape remains uncertain, our ambitions remain unchanged: we are committed to growing the meeting and expanding its global reach.

We anticipate a significant increase in international participation and this will be a unique opportunity to forge new connections, strengthen collaborations, and explore fresh directions in Earth and planetary science. So, now is the time to start planning. Bigger, better, and more connected—JpGU-AGU Joint Meeting 2026 awaits!
