The '''Japan News Network''' ('''JNN'''; {{Langx|ja|ジャパン・ニュース・ネットワーク|Japan Nyūsu Nettowāku}}) is a Japanese commercial [[television network]] run by [[TBS Television (Japan)|TBS Television]], owned by [[TBS Holdings]] (which is a part of the [[Mitsui|Mitsui Group]] ''[[keiretsu]]'' and highly cooperating with the ''[[Mainichi Shimbun]]'' despite the lack of the latter's shareholding in TBS Holdings). The network's responsibility includes the syndication of national television news bulletins to its regional [[Network affiliate|affiliates]], and news exchange between the stations. Its affiliate stations also broadcast non-news programs originating from TBS Television. Founded on 1 August 1959,<ref name="TBS50yrs" />{{Rp|page=150–151}} JNN is made up of 28 full-time affiliates.

It also operates the 24-hour [[Satellite television|satellite]] and [[Cable television|cable]] [[news channel]] [[TBS News (channel)|TBS News]] and the [[Free ad-supported streaming television|FAST Channel]] '''TBS NEWS DIG'''.<ref>{{Cite web |title=「TBS NEWS DIG Powered by JNN」がU-NEXTに登場。24時間365日「今を知る」サービスへ {{!}} U-NEXT コーポレート |url=https://www.unext.co.jp/ja/press-room/tbs-news-dig-2024-03-01 |access-date=2024-03-27 |website=U-NEXT corporate |language=ja |archive-date=27 March 2024 |archive-url=https://web.archive.org/web/20240327002032/https://www.unext.co.jp/ja/press-room/tbs-news-dig-2024-03-01 |url-status=live }}</ref>

==History==

=== Initial news exchange agreement ===
In 1956, when there were only four commercial television stations in Japan ([[Nippon TV|Nippon Television]], Tokyo Radio and Television (hereinafter referred to as KRT), Osaka Television Broadcasting, and [[Chubu-Nippon Broadcasting|Chubu Nippon Broadcasting]]), the television network was quite loose. Nippon Television and KRT in Tokyo had to sell their programs to the two commercial stations (Osaka TV Broadcasting and Chubu Nippon Broadcasting) outside of Tokyo as much as possible in order to recoup their production costs and meet the needs of advertisers. This puts the two stations in an advantageous position by allowing them to freely choose the programs they want to syndicate.<ref>{{Cite book |url=https://worldcat.org/oclc/12164852 |publisher=Nippon Television |year=1978 |language=ja |script-title=ja:大衆とともに25年 |trans-title=25 Years with the Public |oclc=12164852}}</ref>{{Rp|page=100}}<ref name=":0">{{Cite book |last=Sadanobu |first=Aoki |url=https://www.worldcat.org/title/674445957 |title=日本の民放ネットワーク : JNNの軌跡 |publisher=Tokyo Broadcasting System |year=1981 |language=ja |trans-title=Japan's Commercial Broadcasting Network : The Trajectory of JNN |oclc=674445957 |access-date=27 July 2023}}</ref>{{Rp|page=7}}On 15 November 1956, four commercial television stations signed the  Memorandum of Understanding on Television Broadcasting Program Exchange among Four Companies, which specifically stipulated matters related to the syndication of programs.<ref name=":0" />{{Rp|page=11–12}}Later, [[Hokkaido Broadcasting]] and [[RKB Mainichi Broadcasting]] joined the agreement, and the four-company agreement was expanded to a six-company agreement. There were no major changes in the contents of the agreement at that time.<ref name=":0" />{{Rp|page=12}}

The agreement later expanded into 10 member stations as [[Sanyo Broadcasting]], [[Nishinippon Broadcasting]], [[Yomiuri Telecasting Corporation|Yomiuri TV]], and [[Television Nishinippon Corporation|Television Nishinippon]] joined into the agreement. With that, the contents of the agreement were drastically changed, centering on special contributions.<ref name=":0" />{{Rp|page=12–13}}In October 1957, the [[Ministry of Posts and Telecommunications (Japan)|Ministry of Posts and Telecommunications]] issued licenses for 34 commercial TV broadcasters as it became the period of rapid expansion of commercial broadcasters in Japan.<ref name=":0" />{{Rp|page=18–19}} The opening of commercial television outside the metropolitan area meant that the importance of interconnection was increasing.<ref name=":0" />{{Rp|page=22–23}}During this period, only a limited number of frequencies available were allocated to few broadcasters, resulting in limited affiliation options for the succeeding broadcasters.<ref name=":0" />{{Rp|page=23–24}}

In October 1958, Osaka Television Broadcasting, RKB Mainichi Broadcasting, and Sanyo Broadcasting were explicitly part of the same syndication as KRT, while the Nippon Television syndication consisted of Yomiuri TV, Television Nishinippon, and Nishinippon Broadcasting, and the other three were cross-networked with a slight advantage for KRT.<ref name=":0" />{{Rp|page=23}}

At that time, Nippon Television, which had its own highlight programs such as baseball broadcasts, was trying to expand its network through the broadcasting rights of sports events.<ref name=":0" />{{Rp|page=24}} In response to the increasing competition with the broadcaster at that time, it then aired drama and news programming.<ref name=":0" />{{Rp|page=24}}The lack of nationwide coverage for commercial broadcasting in Japan makes it even more crucial for local operators to work together while gathering news.<ref name=":0" />{{Rp|page=24–25}}In June 1958, KRT, Chubu-Nippon Broadcasting System, Osaka Television Broadcasting, RKB Mainichi Broadcasting, and Hokkaido Broadcasting began to exchange news materials through a network agreement.<ref name=":0" />{{Rp|page=25}}

=== Establishment of Japan News Network ===

The broadcast of the wedding of Crown Prince [[Akihito]] (later the 125th Emperor, now Emperor Emeritus) and Crown Princess [[Empress Michiko|Michiko]] (now Empress Emerita) on 1 April 1959, played an important role in bringing about the final signing of the news agreement.<ref name=":0" />{{Rp|page=33–36}} On 1 August 1959, with the signing of the new news agreement, the first true national commercial TV network in the country - Japan News Network - was formally established.<ref name=":0" />{{Rp|page=1}}

The charter members of the network were: KRT (now known as [[TBS Television (Japan)|TBS Television]]), the network flagship station, Hokkaido Broadcasting, [[Tohoku Broadcasting Company|Tohoku Broadcasting]], [[Shizuoka Broadcasting System|Shizuoka Broadcasting]], [[Shin-etsu Broadcasting]], [[Broadcasting System of Niigata]], [[Hokuriku Broadcasting Company|Hokuriku Broadcasting]], Chubu-Nippon Broadcasting, Osaka Television Broadcasting (which later merged with [[Asahi Broadcasting Corporation]]), [[Nihonkai Telecasting]], Sanyo Broadcasting, [[RCC Broadcasting]], RKB Mainichi Broadcasting, [[Nagasaki Broadcasting]], [[Kumamoto Broadcasting]], and [[Minaminihon Broadcasting]].<ref name=":0" />{{Rp|page=1–2}}Upon the establishment, it already had 16 stations or covered about 80% of Japan's population at that time.<ref name=":0" />{{Rp|page=1–2}}Prior to its establishment, there were proposed names for the network which includes Sakura News Network and All-Japan News Network (not to be confused with [[All-Nippon News Network]], which was established in 1970), but it then adopted the current name at the end.<ref name=":0" />{{Rp|page=2}} As stipulated in the network agreement:

* TBS and the member affiliates of the JNN network agreed, upon the creation of JNN, to share news information between the networks while providing both national content for JNN programming produced by TBS and regional news items for their respective programs within their broadcast markets
* TBS' non-news programming are to be aired on the JNN network as well
* TBS prohibited the regional members from airing programming, including news, from its competitor stations

In the early days, each station was free to replace the title of the news program, but on 31 March 1975, after the affiliation change in Kansai from Asahi Broadcasting TV to [[MBS TV|Mainichi Broadcasting]], all network member stations' news branding was unified on the JNN system, with TBS-produced newscasts airing on the regional stations while regional broadcasters provided local content and reporters and news crews for the national programs.<ref name=":0" />{{Rp|page=149–152}}

[[File:JNN ID map (en).png|thumb|right|243x243px|[[Virtual channel|LCN]] assignments of JNN affiliates]]

Until 1992 (when [[i-Television]] in Ehime became the last broadcaster to be affiliated with JNN), multiple broadcasters either dropped their affiliation with JNN (such as Nihonkai Telecasting when [[Broadcasting System of San-in]] started broadcasting<ref name=":0" />{{Rp|page=38}}) or have joined JNN upon their establishment (such as [[Iwate Broadcasting Company]],<ref name=":0" />{{Rp|page=38}} [[Ryukyu Broadcasting Corporation|Ryukyu Broadcasting]],<ref name=":0" />{{Rp|page=38}} and [[Aomori Television]]<ref name=":0" />{{Rp|page=153–156}}). At present, it consists of 28 full-time stations. There are no JNN member stations in Akita, Fukui, Tokushima, and Saga prefectures.

On April 21, 2025, the JNN Park at Akasaka Park Tower opened, centralizing the operations of the Tokyo branch offices of 11 JNN affiliates into one floor. The area includes shared spaces such as conference rooms, phone booths and concentration booths.<ref>{{cite news |title=JNN系列11社の東京支局がワンフロアに 「JNN Park」が本格始動 |url=https://ssl4.eir-parts.net/doc/9401/ir_material3/249062/00.pdf |date=April 21, 2025 |work=[[TBS Television (Japan)|TBS Television]] |language=ja |access-date=25 April 2025}}</ref>

==List of affiliates==

| Initially, it was assumed that KNB would become an affiliate with Radio Tokyo Television (now TBS Television) due to its network agreement with the neighboring JNN stations. However, KNB ultimately decided to prioritize affiliating with Nippon TV, driven by factors such as the station's strong sales performance during broadcasts and its existing contracts to air professional baseball games.<ref>"Northern Japan Broadcasting 10 Year History" (April 17, 1962, North Japan Broadcasting) pp. 232-233 "Network Problems".</ref>

| Initially, the decision was made to affiliate with Nippon Television due to its higher popularity at the time of the station's opening and technical-related issues. In 1970, after resolving the issues, the second commercial broadcasting station was supposed to be affiliated with Fuji TV ([[TV Kochi]]). However, the relationship between the company and Fuji TV deteriorated, prompting consideration of a switch to TBS, which would have involved leaving the NNN network and joining JNN. Fortunately, TV Kochi, the second station, joined JNN just before the new station launched, rendering the affiliation change unnecessary.<ref>{{Cite book |title=高知放送三十年史 |trans-title=30 Year History of Kochi Broadcasting |oclc=672738557}}</ref>{{Rp|page=256, 258-259, 279}}
