Summary

documented Japanese mainstream media is owned by five conglomerates — Yomiuri, Asahi, Nikkei (Nihon-Keizai), Mainichi and Fuji-Sankei — alongside the public broadcaster NHK.1 documented Japan does not regulate cross-ownership of newspapers and broadcasters, which RSF describes as producing "extreme media concentration."1 documented Two wire services, Kyodo and Jiji, supply copy that many smaller papers run largely unmodified.4

The five conglomerates

Group Flagship daily Broadcast arm (indicative)
Yomiuri Yomiuri Shimbun Nippon TV
Fuji-Sankei Sankei Shimbun Fuji Television
Asahi Asahi Shimbun TV Asahi
Mainichi Mainichi Shimbun TBS
Nikkei Nikkei TV Tokyo

documented Newspaper–broadcaster pairing is the norm rather than the exception, and because there is no cross-ownership rule, the same corporate group can hold both a national daily and a terrestrial network.1 This is the structural reason a "media" story in Japan is usually also a corporate-group story.

Public broadcasting and the wires

  • NHK is one of the world's largest public broadcasters, funded by a licence fee; it is the outlet the public rates most trustworthy, ahead of newspapers.2
  • Kyodo and Jiji are the two domestic wire services. Kyodo's syndicated editorial drafts are used by many local papers — a point of longstanding conservative criticism and the factual basis for the claim that local editorial voice is less independent than it looks.4

What this implies for the rest of the bundle

  1. A left-leaning voice has to exist inside a system where the two most-circulated dailies are conservative-leaning and the largest single broadcaster is public and contested.1
  2. Because broadcast and print are paired, commercial pressure on one rarely stops at one.4
  3. Because local papers lean on wire copy, national editorial tone propagates further than circulation numbers suggest.4
