To all participants of EAMA 11,

Thank you very much for joining EAMA11 held last week at Toki Messe in Niigata. With 170 participants, 85 oral presentations, and 84 poster presentations, the meeting was a great success, and on behalf of SOC, I would like to express our sincere gratitude to you once again. We truly hope that the discussions at EAMA11 will further strengthen collaboration among the institutions and researchers across Asia and beyond, which will eventually contribute to the advancement of astronomy. We also look forward to meeting you again in person at the next opportunity.

Sincerely yours,

Mareki Honma
On behalf of SOC

Welcome Message


We are delighted to announce and invite you to the 11th East-Asian Meeting on Astronomy (EAMA11), which will be held in Japan at TOKI MESSE (Niigata Convention Center) in Niigata City, Niigata Prefecture, from December 8 to 12, 2025.

The East-Asian Meeting on Astronomy (EAMA) series was initially established to bring together East Asian astronomers to foster regional collaboration in research and development. The previous meeting, EAMA10, was held in 2016, with subsequent gatherings postponed partly due to the COVID-19 pandemic. EAMA11, the upcoming gathering hosted by the National Astronomical Observatory of Japan (NAOJ), will broaden its scope to encompass astronomical researchers across Asia and beyond, providing a valuable platform for researchers to reconnect, share ideas, and promote collaboration. We solicit talks on regional activities, current and upcoming large-scale facilities, recent scientific discoveries, astronomy education and public outreach. We encourage regional researchers to actively participate, build lasting friendships, and develop future collaborative projects.
