Lorsta Hokkaido Japan

About this Unit

**LORSTA Hokkaido, Japan** was a Long Range Navigation (LORAN) station operated by the United States Coast Guard and located on the northern Japanese island of Hokkaido. Established in the late 1950s, the station played a crucial role in the LORAN-C navigation system, providing precise positioning data to U.S. and allied military and civilian vessels operating in the northwest Pacific region during the Cold War. LORSTA Hokkaido supported both strategic and tactical operations, especially in the context of monitoring Soviet naval activity and supporting U.S. forces stationed in Japan and the western Pacific. The station was eventually decommissioned as satellite-based GPS navigation rendered LORAN technology obsolete in the late 20th century.
