Overview ▶︎Railways, buses, airlines, ferries, and shared bicycles. Association for Open Data of Public Transportation, in collaboration with the Ministry of Land, Infrastructure, Transport and Tourism(MLIT), is working nationwide to make Japan's public transportation data — often said to be the most complex in the world — available as open data.
This contest will also collaborate with the MLIT's "COMmmmONS" project to promote digital transformation of regional transportation, and will work to make data on demand transportation public, as well as to enrich data on barrier-free access.
We look forward to the passionate challenges of developers from all over the world, who will use data to create new services, resolve social issues such as eliminating "traffic gaps" and combating overtourism, and realize digital transformation of regional transportation.
