NHK Yamagata Broadcasting Station
From Wikipedia, the free encyclopedia
The NHK Yamagata Broadcasting Station (NHK山形放送局, NHK Yamagata Hōsō Kyoku) is a unit of the NHK that oversees terrestrial broadcasting in Yamagata Prefecture. The station uses the JOJG and JOJC calls.
It started broadcasting on November 30, 1936; JOJC followed on December 1, 1948. JOJG-TV started broadcasting on December 19, 1959, JOJC-TV followed on November 1, 1962.
On June 1, 1964, JOJG-FM started test broadcasts; stereo programs followed this route: the signal originated in Sendai, which was then transported to Fukushima and, from there, relayed to Yamagata.[1] Color broadcasts started on both JOJG-TV and JOJC-TV on March 20, 1966, when NHK Educational TV converted most of its stations.[2] In early October 1971, local news items began to be shot on color film.[3]
In 1977, work to convert local operations to stereo started.[4] Full-time stereo broadcasting on JOJG-FM began on February 28, 1982.[5] Television stereo broadcasts began on JOJG-TV on February 21, 1986,[6] while JOJC-TV followed on March 21, 1991.[7]
Local programming was added to NHK+ on June 5, 2023,[8] followed by its 8:45pm newscast on September 16, 2025, alongside other local stations.[9]
