JOOY-DTV (channel 4), branded as Mainichi Broadcasting System (Japanese: 毎日放送, Hepburn: Mainichi Hōsō; MBS) (formerly known as Mainichi Broadcasting System Television from 1959 to 2011), is a Japanese television station serving as the Kansai region key station of the Japan News Network. It is owned and operated by Mainichi Broadcasting System, Inc., a subsidiary of MBS Media Holdings, with its studios based in the Kita-ku ward of Osaka.

From its inception in 1959 until 2021, MBS operated as a unified broadcaster, with its radio and television operations remaining intact until 2017, when a major restructuring placed the operations under the second incarnation of MBS. In 2021, the radio division was spun off as a separate, wholly owned subsidiary.
