Jōmō Shinbunsha is the publisher of the Jōmō Shimbun, a regional daily newspaper serving Gunma Prefecture in Japan. According to the company's own advertising information, the Jōmō Shimbun has walked alongside the people of the prefecture for more than 130 years and is the newspaper read by the largest number of people in Gunma. This places its origins in the late 19th century, a period when regional newspapers were being established across Japan. Over the decades the company developed into a full-service regional media organization. It built a network of local bureaus and departments, including branch offices such as the Ōizumi and Tomioka bureaus, and it expanded beyond straight news reporting into sports coverage, cultural features, serialized fiction and columns, and community events. Its editorial products include high-school baseball specials, coverage of local professional and semi-professional teams such as Thespa Gunma and the Gunma Pegasus, and long-running columns. In the digital era, Jōmō Shinbunsha launched the Jōmō Shimbun electronic edition and a news app, and it maintains a wide array of official social media accounts on platforms including X, Facebook, Instagram, Threads, YouTube, LINE, TikTok, and note. These accounts cover news, sports, high-school baseball, culture, events, recruitment, and lifestyle topics, reflecting the company's role as a broad community information provider. The company also carries syndicated international content, including the Japanese edition of The Wall Street Journal. As a regional publisher, Jōmō Shinbunsha operates as a privately held company rather than a listed corporation. Its business model combines subscription and single-copy newspaper sales with advertising revenue, event sponsorship and organization, and digital services. Its advertising rate card, revised in 2026, lists rates for general, special, and classified advertising, and the company produces planned advertising and media kits for advertisers. The company's brand remains closely identified with Gunma Prefecture and with the daily information needs of its residents.
