The Ministry of Land, Infrastructure, Transport and Tourism (国土交通省, Kokudo-kōtsū-shō), abbreviated MLIT, is a ministry of the Japanese government. It is responsible for one-third of all the laws and orders in Japan and is the largest Japanese ministry in terms of employees, as well as the second-largest executive agency of the Japanese government after the Ministry of Defense. The ministry oversees four external agencies including the Japan Coast Guard, the Japan Meteorological Agency and the Japan Tourism Agency.

MLIT was established as part of the administrative reforms of January 6, 2001, which merged the Ministry of Transport, the Ministry of Construction, the Hokkaido Development Agency [ja] (北海道開発庁 Hokkaidō-kaihatsu-chō), and the National Land Agency [ja] (国土庁 Kokudo-chō). Before the ministry renamed itself on January 8, 2008, the ministry's English name was "Ministry of Land, Infrastructure and Transport".
