What RNB Corporation does

RNB Corporation (legal name: Nankai Broadcasting Co., Ltd., 南海放送) is a privately held regional broadcasting company headquartered in Matsuyama, Ehime Prefecture, Japan, with a 60+ year operating history. It is the only dedicated local broadcaster serving Ehime Prefecture's approximately 1.3 million residents, operating a television channel, FM radio station (FM Nankai Broadcasting, rebranded from Fnam in July 2026), an on-demand subscription streaming service accessible via stores.jp, a mobile app, and a fixed-point live camera network across all 12 municipalities of the prefecture. AM broadcasting was fully suspended on February 10, 2026, in favor of FM and FM supplementary broadcasting. Core programming includes daily local news (NEWS CH.4, weekdays 6:15 PM), lifestyle/variety shows (もぎたてテレビ, ビーンズmorning, ミズタのレシピ！), and original local TV dramas.

The company's revenue model is multi-stream: traditional TV and radio advertising, on-demand video subscription fees, event ticket sales and sponsorships, and ancillary services. Distribution is anchored in owned broadcast infrastructure (TV, FM, live cameras) and extended nationally via radiko streaming, YouTube channels, the RNB mobile app, and the stores.jp on-demand platform. Beyond core broadcasting, RNB operates a portfolio of community-oriented businesses and sub-brands — RNB Entertainment Media (lifestyle/travel content), RNB Liver Project (talent development), Proglab Matsuyama (children's coding/robotics education), RNB Drone School (pilot training), RNB Housing Exhibition, and the Akekama Lemon Dig agricultural startup — alongside event franchises such as the Ehime Marathon, Job Kids Ehime, concerts, and the disaster preparedness project. In 2026, RNB signed a DX partnership with Geotect Technologies to support data-driven regional content and community revitalization, and won top honors in two television categories at the Japan Private Broadcasting Union Award (Chugoku-Shikoku regional review).
