Remote Japanese military airfield on a Pacific atoll.
Location
Minami Torishima, Japan
JMSDF Minami Torishima Air Base is a Japan Maritime Self-Defense Force installation located on Minami Torishima (Marcus Island), a remote coral atoll in the northwestern Pacific Ocean. The island lies approximately 1,900 kilometers southeast of Tokyo and is Japan's easternmost territory.
The base serves primarily as a military and meteorological outpost, supporting JMSDF patrol and surveillance operations over a vast stretch of the Pacific. It also hosts a Japan Meteorological Agency weather station. Commercial access to the island is extremely restricted, and no civilian airline service operates there.
Despite having IATA code MUS and ICAO code RJAM, the facility functions exclusively as a military airfield with no public terminal infrastructure. Supply and personnel rotation are conducted via military and government aircraft.
