Naval Computer and Telecommunications Station Yokosuka, Japan

The Naval Computer and Telecommunications Station Yokosuka, Japan is part of the Naval Computer and Telecommunications Station Far East (NCTS FE): nine geographically-dispersed sites in Japan, South Korea, Singapore, Guam, and Diego Garcia. NCTS FE stretches from Misawa in the north to Diego Garcia south of the equator and from Yokosuka in the east to Jinhae-gu, South Korea in the west.

1951–1960
NAVCOMTELSTA Far East was originally designated as Naval Communications Facility, Yokosuka Japan; it was commissioned on 8 January 1951, after the outbreak of the Korean War. In December 1952 U.S. Naval Radio Receiving Facility Kami Seya, Japan was completed, and the Security Group Department and general-service receivers were moved to Kami Seya. During the war, the rest of NAVCOMMFAC Yokosuka moved to Kami Seya. In 1960, the command was re-designated U.S. Naval Communications Facility Japan and relocated to Yokosuka. The following year, the command was again re-designated as U.S. Naval Communications Station, Japan.

1990s–present
This name lasted until 1991, when it was changed to U.S. Naval Computer and Telecommunications Station, Japan to acknowledge the increasing reliance on computers and telephones in telecommunications. Also in 1991, NTCCs Atsugi and Sasebo and NAVCOMM Dets Okinawa and Misawa were functionally transferred to NAVCOMTELSTA Japan. 1993 saw the transfer of Base Communications Offices (BCOs) at Atsugi, Sasebo and Yokosuka to NAVCOMTELSTA Japan. In 1995 another name change to U.S. Naval Computer and Telecommunications Station, Far East occurred, with the transfer of the Communications Department from Commander Fleet Activities Chinhae, Korea to this command and the establishment of NAVCOMM Det Chinhae.
