Community Events
FOSS4G Hiroshima 2026 is inviting applications for community events to be held during and around the conference period.
Community events are organized and run by individual communities. They are intended to provide opportunities for participants to connect, share knowledge, and engage with one another. Possible formats include meetups, study sessions, social gatherings, and other community-led activities.
The organizing team will review submitted information and, where appropriate, help promote events through the official website and provide support with venue coordination.
When to Hold a Community Event
Community events may be held during the FOSS4G Hiroshima 2026 conference period, as well as on the days before or after it. In particular, the following time slots are likely to work well, as they are less likely to overlap with the main conference program:
- Mornings during the workshop period (Aug 30–31)
- Evenings during the workshop period (Aug 30–31)
- Mornings during the main conference period (Sep 1–3)
- Open slots during the main conference period
- During the community sprint period (Sep 4–5)
Events may also be held outside these suggested times. If you have a preferred date or time, please include it in the application form below.
Venue
In principle, each community is expected to arrange its own venue. However, if you would like to hold your event at the Hiroshima International Conference Center, the main venue of FOSS4G Hiroshima 2026, the organizing team may be able to assist with venue coordination.
If your venue is not yet decided, or if you would like to request a space at the Hiroshima International Conference Center, please indicate this in the application form.
How to Apply
If you would like your community event to be listed and announced as part of FOSS4G Hiroshima 2026, please complete the application form below.
Notes
- All submissions will be reviewed by the organizing team before publication.
- Venue support cannot be guaranteed.
- Each community is responsible for planning and running its own event, including participant management.

| 4 | QGIS Japan Community Activities Planning Meeting Until now, the OSGeo Japan Chapter has served as the official QGIS community in Japan, facilitating information exchange among QGIS users; however, in recent years, the scope of its various activities has become somewhat unclear. Since QGIS users from Japan will be gathering at FOSSG Hiroshima, we would like to use this community event as an opportunity to organize and discuss the future activities of the QGIS Japan Community. We hope you will join us in this discussion about the QGIS Japan Community and share your candid opinions. Let’s work together to make the QGIS Japan Community even more vibrant! Anyone can participate in this event.

| 6 | XR meets FOSS4G: Practical and open Exchange on AR, VR and Geospatial Use Cases XR and Geospatial Community Roundtable Extended Reality (XR) is becoming increasingly relevant for geospatial applications, including immersive map visualization, digital twins, field navigation, training, remote collaboration, and spatial data exploration. This community event will provide an open and informal space for participants interested in the intersection of XR and geospatial technology. The event aims to bring together practitioners, developers, researchers, and organizations who are experimenting with or already using AR, VR, and mixed reality in geospatial contexts. The discussion will focus on practical experience rather than product presentations. Topics may include XR hardware, development environments, SDKs, implemented use cases, technical and organizational challenges, lessons learned, AR navigation, map overlays, spatial annotations, indoor/outdoor positioning, and the visualization of geodata in immersive environments. --- Event Details Date : August 31 , 2026, 14:00 PM to 16:00 PM Planned venues : RCC Bunka Center Room702(5-11 Hashimoto-cho, Naka-ku, Hiroshima City, Hiroshima Prefecture) Participation : Open to participants interested in AR, VR, mixed reality, geospatial visualization, navigation, open-source tools, and practical lessons learned URL: - |
