In response to the March 11, 2011 earthquake and tsunami in Japan, the Sahana Software Foundation supported a local effort by the Hyogontech open source group in Kobe to provide a Japanese version of Sahana Eden software for use by government and responding charitable organizations (NPOs). The site registered requests for assistance and information by local government and volunteer organizations that were taking part in the response and recovery efforts.  The site included information on the location of shelters, volunteer activities, soup kitchens, and organizations,  and was supported by a team of volunteer developers in Japan, the Sahana Software Foundation and the Sahana Eden project.  Hosting was donated by IBM Japan’s cloud hosting services.

The National Library of Medicine’s hosted Sahana Vesuvius People Locator was also set up to allow for searching or reporting missing and found persons information to the linked Google Person Finder registry that has collected information on over 600,000 persons.
