Japan Satellite Television

Background
Japan Satellite Television is a British television channel broadcasting Japanese programming serving viewers in Europe, the Middle East and North Africa. It was launched in early 1990 by Marubeni-Iida in association with the Mitsukoshi department store chain. On May 16, 2023, NHK Cosmomedia Europe has announced that it plans to shut down the JSTV service at the end of October 2023. From September, as part of a transitional measure, JSTV1 will relay NHK World Premium on an eight-hour delay and JSTV2, the same but live until the closure of the channels. Following the closure, NHK World Premium will replace JSTV.
