The Japanese OSM community had a very successful year 2010, a steadily growing community and lots of plans for 2011. We established the OSM Foundation Japan on Christmas 2010 and received a large donation of vector data.
Right after the announcement Japan was hit by a 9.0 earthquake and a huge Tsunami, that killed thousands of people and devastated wide areas along the Pacific coast of Eastern Japan.
This talk will explain how the earthquake changed the situation for OpenStreetMap in Japan, how priorities and plans shifted from one day to the next. Within a few hours the Humanitarian OSM Team and the local Japanese community were on hand to help. In a short time volunteers from various projects and communities helped to setup some infrastructure to collect, organize and distribute existing data sources, and to improve the coverage and quality of the available OpenStreetMap data.
Furthermore you will hear about the difficulties and specific characteristics of mapping in Japan and how localized information and software is a crucial point for the success of OpenStreetMap.
