What RKB Mainichi Broadcasting does

RKB Mainichi Broadcasting (RKB毎日放送) is a privately held regional commercial broadcaster founded in 1951 and headquartered in Fukuoka, Japan. The company operates terrestrial television broadcasting on Channel 4 across Fukuoka and Saga prefectures as a JNN (Japan News Network) affiliate, alongside FM and AM radio broadcasts through the JRN network. Its content slate spans daily news (including 24-hour streaming via RKB NEWS 24), sports coverage anchored by Fukuoka SoftBank Hawks baseball and regional marathons, drama and variety programming, and local documentaries. Digital extensions include on-demand streaming via TVer and YouTube, radio streaming via radiko, and podcast production through Podcast Lab. Fukuoka.

RKB monetizes primarily through television and radio advertising sold to local businesses, national brands, and government organizations. Revenue is supplemented by e-commerce (RKB e! Marché), TV and radio shopping programs (KaiMONO Lab and infomercial-style programming), event organization (concerts, sports tournaments, and festivals such as JIM BEAM SUMMER FES and the Fukuoka Sleep Fair), and program-related merchandise. The company engages audiences across owned digital channels — official website (rkb.jp), X (Twitter), YouTube, LINE, and a viewer submission platform — alongside its physical event venues.

RKB operates as a subsidiary within the RKB Mainichi Holdings corporate group. Strategic alliances include core network affiliations with JNN and JRN, cross-border content production with Jeju tourism authorities and the Korea Tourism Organization Fukuoka office, regional event co-organization with Kurume University for the Fukuoka Sleep Fair, and operational cooperation with FBS on helicopter-based disaster reporting. The company competes as one of several regional broadcasters in the Fukuoka/Saga market and competes for advertising share against national networks and digital platforms.
