Shinano Mainichi Shimbun - Shinano Mainichi Shimbun

Nagano Prefecture's leading daily newspaper. Its predecessor was the Nagano Shinpo, first published in July 1873 (Meiji 6). It changed titles and split up many times in the beginning, but in 1890 it was reorganized as a joint-stock company and the foundations of the company were laid. Since then, it has promoted freedom and progress under a company motto of strict neutrality, with editors such as Yamaji Aizan, Kiryu Yuyu, Kazami Akira, and Machida Shishiro. During World War II, it absorbed and merged various newspapers in the prefecture to become one newspaper per prefecture, and continued to develop after the war on that foundation. In 1961 (Showa 36), it achieved full mechanization using kanji teletype, the first in Japan. Since then, it has striven to improve and develop the newspaper production process, such as putting the computerized phototypesetting system COSMOS into practical use (1979), completing an energy-saving factory (1980), and introducing the New Cosmos production system, which features automatic typesetting technology using AI (artificial intelligence). It boasts an overwhelming share of circulation within Nagano Prefecture, with a circulation of approximately 484,300 copies for the morning edition and approximately 46,200 copies for the evening edition (April 2011).

長野県の代表的日刊紙。前身は1873年（明治6）7月創刊の『長野新報』。当初は改題、分裂を繰り返したが、1890年に株式会社に改組して社礎が築かれた。以後、主筆に山路愛山(やまじあいざん)、桐生(きりゅう)悠々、風見章(あきら)、町田梓楼(しろう)などを迎え、厳正中立の社是のもと、自由・進取の主張を展開した。第二次世界大戦中、県下各紙を吸収合併して1県1紙となり、戦後、その基盤にたって発展を続けた。1961年（昭和36）日本で初めて漢字テレタイプによる全面機械化を達成。以後、電算写植システムCOSMOSの実用化（1979）、省エネ工場の完成（1980）、AI（人工知能）を使った自動組み版技術を特徴とする制作システム「ニュー・コスモス」の導入など新聞製作工程の改良・開発に努めている。長野県内では圧倒的な発行部数のシェアを誇り、発行部数は朝刊約48万4300部、夕刊約4万6200部（2011年4月）。
