Industry newspaper - gyokaishi

A specialized newspaper within a specific industry. It is often edited and published with the intention of targeting readers who are involved in that industry. While specialized newspapers can be classified as specialized newspapers for politics, economics, industry, book reviews, sports, education, etc., trade newspapers can be classified more specifically as industry-specific newspapers that handle information within each individual industry. They are sometimes called internal reports or internal reports. In English, they are called trade papers or business papers. They are published in various formats such as daily, weekly, seasonal, and monthly, and some are in the form of magazines that can be called industry journals.

In Japan, trade papers were born and developed around the 1890s along with the development of capitalism, but during World War II, newspaper controls were imposed in 1941 (Showa 16), resulting in a system of one newspaper per prefecture, and many of today's trade papers were launched after the war. The Japan Specialized Newspaper Association is an organization for trade newspapers, and as of January 2011 (Heisei 23), it had 95 member companies, but it is estimated that since the mid-1980s there have been more than 1,000 companies in Tokyo alone, making it extremely difficult to grasp the actual numbers and types.

特定業界内の専門紙。読者も、当該の業界関係者を予定して編集発行されるものであることが多い。専門紙が、政治、経済、工業、書評、スポーツ、教育の専門紙といったように把握できるのに対し、業界紙は、さらに細かく、各個別産業内の情報を取り扱う業界専門紙ということができる。内報、内報紙と称されることもある。英語ではtrade paper, business paperといわれる。刊行形態は日刊、週刊、旬刊、月刊などさまざまで、業界誌というべき雑誌形態のものもある。

　日本では資本主義の発達とともに、1890年代ごろに誕生、発展していったが、第二次世界大戦中、1941年（昭和16）の新聞統制で一県一紙体制とされ、現在の業界紙の多くは戦後に創刊された。業界紙の団体としては日本専門新聞協会があり、2011年（平成23）1月時点で95社がこれに加盟しているが、1980年代中ごろから東京だけで1000社以上が存在するという推定もあり、その数と種類の実態はきわめてつかみにくい。
