STCC operates multiple domestic tracking stations. Among them, the four major stations are listed below.
- Okinawa Tracking and Communications Station (Okinawa Pref.)
Founded in 1968, Okinawa Tracking and Communications Station is located in the southernmost site as a domestic station, where tracking and data acquisition of WINDS ("KIZUNA"), a geostationary satellite stationed above the equator, and QZS-1 ("MICHIBIKI") is conducted.
- Masuda Tracking and Communications Station (Kagoshima Pref.)
Founded in 1974, Masuda Tracking and Communications Station is not only equipped with tracking and control facilities but also with launch monitoring facilities that tracks launch vehicles by a precision radar, receives telemetry signals from the vehicle, and monitors travelling status of the vehicle.
- Katsuura Tracking and Communications Station (Chiba Pref.)
Katsuura Tracking and Communications Station was founded in 1968 and is located in the central region of Japan. The station is characterized by the capability to distribute observation data in a limited time.
- Usuda Deep Space Center (Nagano Pref.)
Usuda Deep Space Center has a large-scale antenna measuring 64 m in diameter which can receive week radio signals from deep space explorers. This antenna was installed in 1984 to support the first Japanese deep space missions MS-T5 ("SAKIGAKE") and PLANET-A ("SUISEI") and later supported operations of "HAYABUSA."
In addition to the above four stations, STCC also runs Uchinoura Space Center (Kagoshima Pref.) where tracking and data acquisition is conducted. The Earth Observation Research Center (EORC) in Saitama Pref. also has antennas which receive earth observation data.
