The Japan Geoscience Union (JpGU) is an academic union that covers all the disciplines of Earth and planetary sciences and related fields. Annually the organisation organises a conference that runs for six-days. The JpGU 2026 will be held as a joint meeting with the American Geophysical Union (AGU) at the Makuhari Messe in Chiba Prefecture for six days from May 24 to 29, 2026.

ELSI will participate in JpGU 2026 with numerous oral and poster presentations, and with an exhibition booth.
